TAD-D700 CD/SACD player January 2023

Technical Audio Devices Laboratories, Inc. (TADL) today announced the TAD-D700 CD/SACD player as the newest addition to its top-of-the-line Reference Series of hi-fi audio components. The TAD-D700 incorporates the third-generation Ultra-High-Precision Crystal Generator (UPCG) and other performance enhancements to replace its predecessor, the commercially and critically acclaimed TAD-D600, introduced in 2010.

Main Features

1) Ultra-High C/N1 Master Clock and third-generation UPCG

The TAD-D700 is equipped with our proprietary Ultra-High C/N Master Clock Circuit. To develop this circuitry, our engineers have refined the physical characteristics of the technology originally developed for high-speed digital communication base stations for achieving high C/N performance. A further tweaking has been made to the circuitry through a series of real-world listening evaluations with a discerning ear. The result is an unprecedented level of accuracy in reproducing signals read out from a CD or SACD, as well as signals fed from external sources. In the third-generation UPCG, the oscillator has been upgraded to one with SC-cut crystal to reduce phase noise and achieve even greater audio and C/N performance.

1. C/N: Carrier-to-noise ratio

2) Outboard power supply unit

The D700’s power supply unit is physically separated from the main unit. This ingenuous design prevents vibrations and leakage magnetic flux from the transformer from affecting the disc-drive unit and audio circuit inside the main unit. To increase the purity of power supply, the internal coil of the transformer is directly connected to the power supply circuit, minimizing the contact points with lead wires. In addition, terminals for directly connected coils, mounting terminals for motherboards, and clamping screws are all made of oxygen-free copper coated with nonmagnetic materials to eliminate even the slightest magnetic distortions. A powerful toroidal transformer with a 400 VA power rating—non uncommon in power amplifiers but unheard-of in disc players—powers the audio circuit to achieve greater signal transition performance. The entire power supply is housed in a rigid cast-aluminum monocoque chassis to suppress unwanted vibrations.

3) Simplified analog audio circuit

TAD’s relentless pursuit of simplicity has culminated in a newly developed current-feedback amplifier that is incorporated into an I/V converter with FET devices—hand-selected and paired by our certified artisans—in its input stage. This design enables a ultra-wide-range signal transmission, resulting in an unprecedented level of accuracy in signal conversion. Our attempt to eliminate magnetic distortion has taken a step further. The nonmagnetic, highly reliable carbon resistors used for feedback resistance contribute to a nonmagnetic signal path.

4) Parallel-connected twin differential D/A converters

Parallel-connected twin Burr-Brown 192-kHz, 24-bit D/A converters help dramatically improve audio performance characteristics, including greater signal-to-noise ratio, linearity, and dynamic range, as well as lower distortion. Audio signals are passed on in their purest form to the analog audio circuit, making it possible to reproduce even minute music signals, which results in finely detailed and densely textured audio reproduction.

5) Silent CD/SACD transport mechanism with high-precision disc loading

The D700 boasts an upgraded CD/SACD transport mechanism to achieve even greater accuracy in signal reading. The sturdy disc transport mechanism comes with a high-precision loading mechanism that opens and closes the disc tray with little vibration, thanks to built-in metal bearings. The pickup employs an infinite conjugate optics system that ensures both stable operation and high-precision signal readout. The rigid disc tray is made of meticulously machined aluminum to suppress vibration and has a vibration-dampening black coating to prevent the diffusion of a laser beam and achieve greater accuracy in signal readout.

6) Robust low-center-of-gravity construction

The main unit is housed on a sturdy double-layered chassis made of an extra-thick cast-aluminum base with three-point support spikes and a 6 mm-thick copper-plated steel chassis to achieve a low-center-of-gravity construction. This design suppresses vibrations to minimize their effect on the mechanism and audio circuit sitting on the chassis.

7) Doubling as a stand-alone D/A converter unit

The D700 is equipped with a high-precision sampling-rate converter that works with the Ultra-High C/N Master Clock Circuit to reclock digital inputs. This makes the D700 double as a high-performance stand-alone D/A converter capable of processing digital signals up to 192 kHz and 24 bit.

TAD-CE1TX-WN Speaker system Late November 2022
TAD-ST2TX-K Speaker stand

Technical Audio Devices Laboratories, Inc. (TADL) today announced the TAD-CE1TX bookshelf-type speaker system as the newest addition to its Evolution Series of hi-fi audio components, replacing its predecessor, the commercially and critically acclaimed TAD-CE1, introduced in 2014.

While inheriting the ingenious Bidirectional Aero-Dynamic Slot (ADS) port from its predecessor, the CE1TX features significantly upgraded woofer and midrange units to achieve further refinement in sound quality. The CE1TX embodies the design philosophy of TAD’s top-of-the-line Reference TX Series speakers to deliver the sound field and imaging performance of the highest level, for which all TAD speakers are known.

Main Features

1) CST Driver delivers ideal single-point-source sound

The CE1TX boasts TAD’s proprietary CST Driver, which controls the directivity of the concentrically mounted midrange and tweeter over an extended frequency range from the point of matching phase. This culminates in clear and solid imaging, as well as natural sound field reproduction. The midrange cone controls the directional characteristic of the concentrically mounted tweeter to bring the phase and directivity of their output in line in the crossover region. The result is ultra-wide-range reproduction from 250 Hz up to 100 kHz by the CST driver alone, while achieving a natural attenuation characteristic and directivity pattern across all bands.

2) Tweeter featuring a beryllium diaphragm

The CE1TX uses a light yet rigid beryllium diaphragm for its tweeter, manufactured with our proprietary vapor deposition technique. We have applied our computer-analyzed optimization technique called Harmonized Synthetic Diaphragm Optimum Method (HSDOM) in designing the form of the diaphragm in order to achieve precise control of its divided vibrations and piston motions, which makes possible ultra-wide-range reproduction of up to 100 kHz.

3) Midrange featuring a newly developed magnesium diaphragm having a high internal loss

The midrange’s diaphragm is made of magnesium, which is one of the lightest metals and has a high internal loss—ideal characteristics for materials to be used for diaphragms. The application of hybrid chemical conversion coating and painting to the surface gives it additional hardness and a yet greater internal loss. The result is clearer, distortion-free midrange reproduction unaffected by unwanted resonance. In addition, resonance in the mid-to-high frequencies generated by interactions between the suspension and diaphragm is effectively controlled to achieve an even lower distortion and a greater transient response.

4) Woofer with a newly developed MACS II* diaphragm

We have refined the woofer diaphragm made of five layers of woven and non-woven aramid fabric to optimize the physical property of the shell-shaped diaphragm that integrates the center cap and cone into a single piece. The result is a richer and clearer bass and the smooth, coloration-free reproduction in the mid-to-low frequency range.

*Multi-layered Aramid Composite Shell Second Generation

5) SILENT* enclosure that combines strength and an outstanding vibration-dampening characteristic

The CE1TX comes in a SILENT enclosure, which combines sturdy birch-plywood braces with medium-density fiberboard (MDF) panels having a high internal loss to provide superb strength and an outstanding vibration-dampening characteristic. The addition of 10 mm-thick hard aluminum side panels further reduces the vibration of the cabinet down to a minimum. Moreover, acoustic absorbent chosen and placed inside the enclosure, based on meticulous analyses of internal standing waves, helps eliminate standing waves that would adversely affect the sound field and imaging performance of the speaker.

*Structurally Inert Laminated Enclosure Technology

6) Bidirectional ADS Port for rich, natural bass

The CE1TX has inherited the Bidirectional ADS Port from its predecessor. This ingenious design places slit-shaped ports (ducts) in both side panels with flared openings to the front and rear to allow air to flow smoothly through them. This design reduces port noise generated at high amplitude levels and keeps internal standing waves from escaping from the ports, resulting in a rich, responsive bass. The symmetrically placed port openings, both laterally and along the front-rear axis, cancel out vibrations from the port movement to deliver a natural bass.

7) Eye-pleasing tropical-olive-grain wood enclosure

For the enclosure of the CE1TX, we have refined the classy tropical-olive-grain wood enclosure of its predecessor to add a mirror finish that gives the illusion of a wet surface and makes the grain stand out. In the manufacturing line, skilled artisans spend hours finishing each enclosure with meticulous care, beginning with applying high-grade, clear coating to the surface and buffing the base coating and finishing with surface polishing.

8) Stylish stand specially designed for the CE1TX (sold only in pairs)

The TAD-ST2TX-K stand specially designed for the CE1TX is built with strength and a high vibration-dampening characteristic to bring out the best of the speaker.

1. Built-to-order model

Technical Audio Devices Laboratories, Inc. (TADL) today announced the TAD-D1000TX SACD/CD player and the TAD-DA1000TX digital/analog converter as the newest additions to its Evolution Series of hi-fi audio components. The TAD-D1000TX and the TAD-DA1000TX replace the highly acclaimed TAD-D1000MK2 and TAD-DA1000, respectively.

To achieve even greater audio performance over their predecessors, the TAD-D1000TX and the TAD-DA1000TX incorporate the third-generation Asynchronous USB Communication Engine and a variety of other engineering refinements.

Main Features

1) Newly Developed Third-Generation USB Communication Engine

All these models are equipped with a USB Audio Class 2.0-compliant USB port driven by the third-generation Asynchronous USB Communication Engine, which we developed in-house. The new USB communication engine is designed to accurately control the reception of digital signals coming from PCs and other digital devices. Moreover, the USB engine can read out digital signals with a high-purity clock to achieve jitter-free, high-precision performance. In addition to ensuring greater signal purity, the USB engine employs a redesigned FPGA (field-programmable gate array) internal circuit to minimize delays and capture DSD256 signals with the sampling rate of 11.2 MHz This results in significantly lower distortion at low signal levels.

2) Ultra-High C/N2 Master Clock UPCG

All these models incorporate the Ultra-High C/N Master Clock UPCG (ultra-high-precision crystal generator), which was originally developed for our top-of-the-line TAD-D600 disc player. This proprietary crystal oscillator is based on technologies developed to achieve high C/N performance at high-speed digital communication base stations and is the result of further refinement of physical characteristics on the drawing board as well as the result of a series of real-world listening evaluations. The crystal oscillator helps achieve an unprecedented level of accuracy in reproducing signals read out from an SACD or CD as well as signals fed from external sources. Furthermore, every digital input and output circuit and USB communication engine has its own newly developed high C/N clock to enable digital signal transmission in the purest form.

2. C/N: carrier-to-noise ratio

3) High-Purity Power Supply

To increase the purity of power supply, the internal coil of the transformer is directly connected to the power supply circuit, minimizing the contact points with lead wires. In addition, terminals for directly connected coils, mounting terminals for motherboards, and clamping screws are all made of oxygen-free copper coated with nonmagnetic materials to eliminate even the slightest magnetic distortions. Furthermore, the transformer is mounted firmly on a 6-mm-thick brass base to suppress unwanted vibration.

4) Low-Center-of-Gravity Structure and Insulators to Achieve Greater Isolation from External Vibration

The combination of a vibration-resistant 8-mm-thick chassis made of solid aluminum and a low-center-of-gravity structure that positions heavier parts and components closer to the bottom keeps external vibration from affecting the unit. The newly developed insulator feet have finely tuned load points and better isolation characteristics and effectively keep audio signals from being masked by vibration-induced distortion.

5) Line Output Volume Control for Direct Connection to a Power Amplifier

The line output has its own high-quality volume control, which enables the unit to be connected directly to a power amplifier, bypassing a preamplifier to simplify the signal path. When directly connected to a power amplifier, the unit serves as a digital media center capable of handling a variety of digital media in the purest form. As an added bonus, the TAD-DA1000TX is equipped with a dedicated headphone volume control.

6) Quiet CD Transport Mechanism with High-Precision Disc Loading (only in the TAD-D1000TX)

The CD transport mechanism enables smooth and high-precision disc loading and keeps external vibration from affecting the servo system. The disc tray is made of rigid machined aluminum to suppress vibration and has a black coating to prevent the diffusion of a laser beam and achieve greater accuracy in signal readout.

TAD-E2-WN

TAD-E2-WN

TADL Introduces the Evolution Series
TAD Evolution Two Floor-Standing Speaker System

TAD-E2-WN

Model Description Available
TAD-E2-WN Speaker system November 2021

Technical Audio Devices Laboratories, Inc. (TADL) today announced the TAD-E2-WN floor-standing speaker system with the “TAD Evolution Two” moniker as the newest addition to its Evolution Series of hi-fi audio components.

Featuring newly developed twin 15.5 cm woofers and a 2.5 cm beryllium tweeter and drawing on a wealth of speaker-engineering ingenuity we have accumulated over the years, the TAD-E2 embodies the long tradition of delivering single-point-source sound for which all TAD speakers are known and takes the sound field and imaging performance to a new level. The speaker enclosure has a classy woodgrain finish that blends into any room decor.

Main Features

1) Tweeter Featuring a 2.5 cm Beryllium Diaphragm Produces a Clear and Natural Sound

As is the case with the TAD-E1TX and TAD-ME1 speaker systems in the Evolutions Series, the TAD-E2 features a tweeter with a 2.5 cm beryllium diaphragm. The shape of the diaphragm is determined by an advanced optimization method based on the HSDOM (Harmonized Synthetic Diaphragm Optimum Method) computer analysis to provide a frequency response up to 60 kHz. The directionality of the tweeter is optimally controlled by a newly developed waveguide on which it is mounted to produce a smooth dispersion of sound over an extended frequency range. The waveguide is made of rigid cast aluminum to suppress unwanted resonance. The result is a polished sound in the mid-to-high frequency range for which all TAD speakers are known.

2) Newly Developed Twin 15.5 cm Woofers Deliver a Powerful Bass with Smooth Directionality

Each woofer employs a 15.5 cm MACC (Multi-layered Aramid Composite Cone) diaphragm. This diaphragm is composed of an Aramid fabric cone on the front and a softwood pulp cone on the back that are formed separately before they are laminated together. This configuration produces a rich and clear bass as well as a coloration-free mid-to-low range sound with excellent linearity. In addition, the woofer cone has a shallowly curved structure to provide smooth directionality and has a reinforcement brace added to its neck that forms a delta bracing structure to reproduce a powerful bass.

3) Crossover Network Filter Enables an Excellent Sound Field and Image Localization

A 2.5-way network filter is employed to achieve an optimum phase rotation between the upper and bottom woofers at the crossover frequency between the tweeter and the woofers. This filter reduces phase interference around the crossover frequency between the twin woofers and the tweeter. The combination of speaker units with outstanding sound directionality and this network filter achieves a natural attenuation characteristic and directional pattern over the entire frequency range, which contributes to a well-focused sound image localization and a precise sound field reproduction.

4) Bidirectional ADP System Produces a Rich and Natural Bass

The Bidirectional ADP (Aero-Dynamic Port) System positions a port on the bottom of the enclosure with its openings to the front and rear of the enclosure. The port has a horn-shaped interior that reduces port noise and achieves greater efficiency in driving the port to help reproduce clear and responsive sound in the mid-to-low frequency range. The symmetrical front-back layout of the port effectively offsets the physical force that vibrates the enclosure and, as a result, helps reproduce a powerful bass.

5) 10-mm-thick Steel Base Plate Adds Greater Stability

A 10-mm-thick base plate made of solid steel is attached to the bottom of the enclosure with resin horn plates inserted between them to suppress the base plate’s vibration. The three spikes attached to the base—two toward the front and one toward the rear—enable the firm placement of the speaker system on any floor surface. The structural design that enables the three spikes to optimally support the position of the system’s center of gravity counterbalances the reaction caused by the powerful driving force of the twin woofers.

6) SILENT Enclosure Dampens Unwanted Resonance

The SILENT (Structurally Inert Laminated Enclosure Technology) enclosure incorporates the combination of MDF (medium-density fiberboard) panels with a high internal loss and rigid birch plywood braces to achieve greater strength and lower resonance. The rounded edge at the top of the baffle reduces the diffraction of the sound waves from the tweeter. In addition, the slanted baffle optimizes the position of the speaker system’s center of gravity and compensates the difference in distance between each speaker unit and the listener to enable a more precise sound field reproduction from this floor-standing speaker system with twin woofers.

7) Woodgrain Satin Finish Gives an Elegant and Classy Look

The enclosure has an open-pore satin finish that retains straight grain. Skilled artisans spend hours in crafting the enclosure with meticulous care—from conditioning the base materials and spraying paint to grinding the base paint and applying matt top-coating—to give it a classy clear matt finish.

PRESS RELEASE

TADL Introduces the TAD-CR1TX Stand-Mount Speaker System,
Which Embodies the Single-Point-Source Sound Concept,
as the Newest Addition to the Reference Series

Pictured with optional TAD-ST1 speaker stands (sold separately)

Model Description Color Available
TAD-CR1TX-EB Speaker system Emerald black June 2020
TAD-CR1TX-BR Speaker system Beryl red June 2020

Technical Audio Devices Laboratories, Inc. (TADL) today announced the TAD-CR1TX stand-mounting speaker system as the newest addition to its top-of-the-line Reference Series of hi-end audio components.

The TAD-CR1TX embodies the same design philosophy and technological innovations that were originally incorporated into our flagship TAD-R1TX floor-standing speaker system, released in July 2019. As we did for the TAD-R1TX, we have collaborated with Tendo Mokko*, a distinguished maker of handcrafted luxury furniture, in designing and crafting a sturdy, vibration-damping enclosure for the TAD-CR1TX to achieve a higher level of sound excellence. Our proprietary coaxial Coherent Source Transducer (CST) Driver plays a critical role in delivering single-point-source sound from this compact speaker system. With the addition of the TAD-CR1TX to the lineup, consumers now have a choice between a floor-standing speaker model and a stand-mounting speaker model from the renowned Reference Series.

Main Features

1) CST Driver Delivers Ideal Single-Point-Source Sound

The CR1TX boasts the coaxial CST Driver, which controls the phase and directivity of the drive unit across a wide frequency range. The midrange cone controls the directional characteristics of the concentrically mounted tweeter and unifies acoustic centers of the tweeter and the midrange so as to integrate the phase and directivity of their output in the crossover region. The result is ultra-wide-range reproduction from 250 Hz to 100 kHz as well as a directivity pattern that neatly dampens uniformly across all bands without disruption. All of this culminates in extremely clear and stable imaging and incredibly rich, natural-sounding reproduction of music.

2) Beryllium Diaphragm for Midrange Cone and Tweeter Dome

The CR1TX uses a beryllium diaphragm for its midrange cone and tweeter dome. Our proprietary vapor deposition technique provides the material with superior strength and uniformity as well as high-frequency resonance-damping characteristics. The midrange unit features an exceptionally large 16 cm-diameter cone that reproduces crystal-clear sound across a wide frequency range. In addition, we applied our own computer-analyzed optimization technique called Harmonized Synthetic Diaphragm Optimum Method (HSDOM) in designing the form of the tweeter’s diaphragm, which enables the precise control of divided vibrations as well as ultra-wide-range reproduction of up to 100 kHz.

3) Woofer Featuring a TLCC Diaphragm

The woofer of the CR1TX has a strong and stiff TLCC (Tri-Laminate Composite Cone) diaphragm made of a core of foamed acrylamide, which is light and rigid polymer often used on airframes, sandwiched front and rear by aramid fibers. The result is fast-response, rich bass free of tonal coloration. The triple-laminated diaphragm, which uses individually molded foamed acrylamide and aramid fibers to take advantage of the anisotropic characteristics of woven fabric, provides an additional benefit of reducing unwanted resonance in axisymmetric modes. Furthermore, the woofer underwent fine acoustic tuning to make the most of a natural-sounding timbre that CST Driver produces.

4) Woofer Driven by OFGMS Magnetic Circuit

To ensure accurate reproduction of complex audio waveforms, the magnetic circuit of the woofer features our proprietary OFGMS (Optimized Field Geometry Magnet Structure) circuit with a short voice coil, designed to linearize the magnetic flux density along a long gap of 20 mm. This circuit stabilizes the woofer’s movement over its entire amplitude range and ensures high drive linearity. An even greater linearity is achieved by the suspension system that employs TAD’s signature corrugated surround.

5) Aerodynamically Optimized Port System

The flare-shaped bass-reflex port is aerodynamically optimized by using the fluid design technology originally developed for TAD horns. This port effectively reduces air noise to a minimum and helps the bass driver unit perform smoothly and deliver a clean, crisp bass sound-even at the limit of its excursion range.

6) Sturdy, Vibration-Damping SILENT Enclosure

The SILENT (Structurally Inert Laminated Enclosure Technology) enclosure of the CR1TX is constructed of laminated parts of different materials to take advantage of both frame and monocoque structures to achieve greater static and dynamic strength and better vibration-damping performance. Its rigid internal frame is made of 21mm-thick birch plywood and clad with 30 mm-thick vacuum-pressed veneer side panels that are glued to laminated MDF panels bended using high-frequency hot pressing. The same hot-pressing technique is also applied to giving an elegant curve to the front baffle and the top of the cabinet. The combination of the flowing teardrop shape of the cabinet and its curved top makes the entire enclosure sturdier, reduces sound diffraction, and minimizes unwanted resonance and internal standing waves.

7) Collaboration with Tendo Mokko in Crafting the Enclosure

We designed and crafted the enclosure for the CR1TX in close collaboration with Tendo Mokko, a luxury furniture maker established in Tendo, Yamagata Prefecture, in 1940. Tendo Mokko has brought to this project its wealth of experience and artisanship in woodworking to help make the already strong SILENT enclosure even sturdier. The CR1TX’s enclosure comes in two colors—Emerald Black and Beryl Red, both of which derive from beryl, a rare mineral that can be processed into beryllium. Emerald Black is associated with a very dark green gemstone; Beryl Red is associated with a red gemstone of beryl. Both finishes offer beautiful texture unique to natural wood and deep gloss with color tones that exude elegance expected of the Reference Series of speakers.

PRESS RELEASE

TADL Introduces the M700 and M700S Power Amplifiers as the Newest Addition to its Reference Series of Hi-Fi Audio Components in Its Relentless Pursuit of Excellence in Sound Quality

TAD-M700
Model Description Available
TAD-M700 Monaural power amplifier December 2019
TAD-M700S Two-channel power amplifier December 2019

Technical Audio Devices Laboratories, Inc. (TADL) today announced the TAD-M700 and TAD-M700S power amplifiers as the newest addition to its top-of-the-line Reference Series of hi-fi audio components. The M700 monaural power amplifier replaces the highly acclaimed TAD-M600, with significantly upgraded design, construction, and components down to the smallest details inside and out. To provide greater versatility, we have added to the lineup the M700S two-channel bi-amp-capable power amplifier.

Main Features

1) Fully Symmetrical Design

The M700 and M700S have BTL (bridged transformerless) configuration that applies balanced connection between two separate but symmetrical amplifiers from input through to output in the amplification stage. This configuration, combined with symmetrical positive and negative power supplies and independently designed power circuits, enables the M700 and M700S to provide identical positive and negative electric currents to the voice coil of a speaker unit and deliver the accurate driving of a diaphragm. Furthermore, the M700 and M700S boast dual monaural construction with a fully symmetrical design for the left and right channels, right down to the circuit topology, PC boards, and wiring.

2) Elaborate Vibration-Suppressing Technology

The M700 and M700S employ a newly designed cast-aluminum chassis that boasts a high internal loss factor for vibration, eliminating inherent sympathetic vibration at unwanted frequencies. Components are laid out optimally inside the chassis to stubbornly resist vibrations induced by sound pressure from a speaker system. In addition, the low-impedance aluminum chassis demonstrates high electric stability.

3) Redesigned Adjustable Spike Feet

The M700 and M700S are supported by four redesigned height-adjustable spike feet, each having a single point of contact with the surface on which it stands. This ingenious design keeps vibration transmitted through the floor from affecting the components inside the case and keeps delicate audio signals from being masked by vibration-induced distortion. The result is more condensed and energetic audio reproduction and yet with spatial nuance of the music retained intact.

4) Redesigned Wide-Stance Chassis

The cast-aluminum chassis more gently curved than the predecessor provides a solid base that suppresses resonance vibration in the audible frequency range. The wide-stance chassis construction, inherited from the TAD-M600 power amplifier, was upgraded to lower the already low center of gravity of the whole unit by optimizing the slant angle of four feet at the corners.

5) Power Amplification That Enables the Powerful Driving of Speakers

The balanced-connected power amplification circuits of the M700 and M700S use high-power multiple-emitter transistors with superior high-frequency performance to provide the stable driving of speakers over wide frequency ranges. In addition, a non-magnetic resistor made of newly developed hybrid resistor elements is used for emitter resistance in the final output stage. All these components of higher reliability employed from the input through to output stages combine to deliver the powerful driving of speakers

6) Extra-Large-Capacity Power Supplies

Our years of expertise in achieving audio quality and reliability has culminated in twin gigantic power transformers with the total ratings of 2.8 kVA. In the production line of the M700 and M700S our certified artisans manually wind insulating sheets around the core of the transformer, eliminating the need for a bobbin so as to increase the binding between the primary and secondary coils. The coil is directly connected to the first stage of amplification to increase the purity of power supply and achieve more responsive and consistent audio reproduction. In addition, four custom-built 33,000㎌capacitors help effortlessly deliver dynamic and lively sound with excellent transient response for which the M700 and M700S were designed.

7) Simplified Voltage Amplification Stage

True to TAD’s long-held design philosophy of “Simple is best,” the M700 and M700S employ an input circuit composed of a matched pair of FET devices to reduce the number of components required to make the circuit down to an absolute minimum, allowing music signals to be amplified in their purest form and go through the circuit without losing even the subtlest information. The new DC servo circuit enables stable amplification, resistant to changes in operating voltage, temperature, and magnitude of input signals. In addition, pairs of FET devices carefully hand-picked by our certified artisans in the production line were incorporated into the amplifier’s input circuit and DC servo circuit, which improves the operational stability of amplification. Moreover, we have taken our attention to detail a step further: we used non-magnetic carbon resistors for feedback resistors to eliminate the effect of magnetic distortion on the signal path.

8) Monaural Power Amplifier and Two-Channel Power Amplifier to Choose from

To provide greater versatility in building a truly high-end audio system, we have added to the lineup the M700S two-channel bi-amp-capable power amplifier. Two units of the M700S, both with the bi-amp mode switched on, in a system can power each speaker unit independently, improving the separation between channels and achieving a more accurate reproduction of sound field and sound image location. The M700 monaural power amplifier and the M700S two-channel power amplifier provide customers with a wider choice to choose from.

PRESS RELEASE

The Next Level of the Reference Series,
in Pursuit of the Ideal Sound

Revealing the Floor Speaker System

TAD-R1TX

TAD-R1TX-EB / TAD-R1TX-BR

Product Name Model Color Release Date
Speaker system TAD-R1TX-EB Emerald black Late July
Speaker system TAD-R1TX-BR Beryl red Late July

Originating from the uncompromising craftsmanship of Technical Audio Devices Laboratories, Inc. (TADL), introducing to the market "the Reference Series", high-end audio in pursuit of the best sound quality, and "the Evolution Series", which incorporates innovative technology, we are proud to introduce a new generation of Reference Series Speaker Systems.

Building on the TAD-R1 and the TAD-R1MK2, which have received excellent ratings on the audiophile market as flagship models of the Reference Series since their original release, we are launching the pinnacle of floor speaker systems, the new TAD-R1TX, as the next generation.

We have pursued sound quality to its utmost limits by pooling the skills of technical experts.  Following the concept of using highest expertise available, the enclosure was produced collaboratively with the luxury furniture manufacturer "Tendo Mokko" in Yamagata.  As a result, TAD has achieved both improved sound quality as well as a visual with a feel and beautiful aesthetic worthy of the name "Reference" through the use of the SILENT enclosure that has evolved further through the artisanal techniques of "Tendo Mokko", the creator of numerous masterpieces, in response to orders from renowned creators all over the world.

Main Features

1) CST driver that embodies the ideal single point sound source concept

TAD uses a CST driver for coaxial speakers that controls the phase and directivity of the drive unit across a wide frequency range. The use of a midrange cone controls the directional characteristics of the concentric mounted tweeter, thereby unifying the acoustic center of the tweeter and the midrange as well as reconciling the phase and directional characteristics through the crossover range. This realizes both ultra wide range reproduction of 250 Hz – 100 kHz and a direct-radiation pattern that neatly dampens uniformly across all bands. The result is extremely clear and stable imaging, a wide frequency response, and incredibly rich and natural sounding reproduction.

2) Woofers with a TLCC (Tri-Laminate Composite Cone) diaphragm

The new R1TX woofers incorporate a "TLCC diaphragm" that achieves fast-response, clear, and rich reproduction with no-coloration, through a structure of lightweight, high-rigidity foamed acrylamide, which is used in aircrafts, sandwiched by aramid fibers, and resulting in improved strength and stiffness.

The TAD engineering team reduced resonance in axisymmetric modes by molding the foamed acrylamide and aramid fibers separately as well as processing them with a lamination method that utilizes the anisotropy of woven fabric.

Furthermore, we have applied acoustic tuning creating a natural sound timbre in association with CST driver.

3) Beryllium diaphragm processed with unique vapor deposition technique for tweeter and midrange

The R1TX uses a beryllium diaphragm for the tweeter dome and midrange cone. A vapor deposition technique uniquely developed by TAD provides superior material strength and uniformity as well as high-frequency resonance damping. The midrange cone features a maximum-size 16 cm-diameter cone for the beryllium diaphragm to realize transparent sound across a wide frequency range. Moreover, TAD used the original computer-analysis optimization method HSDOM (Harmonized Synthetic Diaphragm Optimum Method) to design the tweeter’s diaphragm shape, achieving accurate control of differential vibration and ultra wide range reproduction up to 100 kHz.

4) Woofers with OFGMS (Optimized Field Geometry Magnet Structure) circuit

In order to reproduce audio waveforms correctly at all times, we use our original magnet-circuit short voice coil OFGMS circuit, which linearizes the magnetic flux density along the 33 mm long gap. This stabilizes operation during wide range amplitude and realizes high movement linearity. Moreover, high linearity is maintained as we also use our original corrugation edge in the suspension components.

5) Port systems that applies TAD horn fluid design

Air noise is effectively reduced by using a flare-shaped port system that is superbly aerodynamic. The unit operates stress-free even during large input and amplitude, producing clear bass with good S/N.

6) SILENT (Structurally Inert Laminated Enclosure Technology) enclosure with high damper effect and strength

The enclosure is made of a laminate structure that combines different materials, and its static and dynamic strength as well as damper effect is maximized by utilizing the merits of its frame and monocoque structure, for example by making the side walls a frame surrounded by strong panels. The enclosure consists of a strong framework with a skeleton of 21 mm-thick birch plywood and a transverse bulkhead that is glued to 50 mm-thick side panels produced with high-frequency hot press forming. Moreover, by building on the teardrop form and rounding the shape of the speaker head, we increase strength, reduce sound diffraction anomalies, and eliminate unwanted resonance and standing waves inside the enclosure.

7) Collaborating with luxury furniture manufacturer "Tendo Mokko" to make the enclosure

TAD designed and constructed the enclosure in collaboration with one of most famous Japanese luxury furniture manufacturers "Tendo Mokko", which was founded in Tendo City, Yamagata in 1940.

The SILENT enclosure has become even stronger by utilizing Japanese traditional artisanal techniques during molding and processing. The new TAD-R1TX line-up now features two exterior colors derived from the rare mineral beryl. One is "emerald black", which describes a deep-green gem, and the other is "beryl red", which describes a red gem made of beryllium. Both are color tones replete with deep luster and elegance, and make the most of the beautiful feel of the natural wood, worthy of the name "Reference."

TAD-M1000-K/S

TAD-M1000-K / TAD-M1000-S

Design concept

Technical Audio Devices Laboratories, Inc. (TAD) announces the launch of the TAD-E1TX-K floor speaker system and TAD-M1000-K/S power amplifier, as new editions to TAD’s “Evolution” series.

The TAD-E1TX-K is a further evolution of the TAD-ME1 — which achieves sound playback with excellent sound field reproduction and audio image localization over a broad frequency range that exceeds expectations for its compact body size—finished into an imposing yet dignified-feeling floor speaker system.

The TAD-M1000-K/S seeks to enhance the overall system aesthetic by adopting a design that matches that of the TAD-D1000 disc player and DA1000 D/A convertor (launched in 2013). The TAD-M1000-K/S comes in a choice of two colors: black or silver. With revisions to the design of its voltage amplification circuitry and power supply grounding, and the adoption of new components, this amplifier delivers further improvements to the high-speed and innovative sound quality already offered by the Evolution series.

Evolution Series:

TAD’s Evolution series incorporates new and innovative technologies while at the same time delivering high-resolution and other digital technologies demanded by customers. Since the launch of the Evolution series TAD-E1 speaker system in 2011, TAD has continued to drive the further evolution of the series by incorporating additional technologies such as bi-directional ADS ports, CST (Coherent Source Transducer) drivers equipped with beryllium and magnesium diaphragms, and other technologies developed through the creation of the TAD “Reference” series, which aims to achieve the very highest sound quality. 

Main Features of the TAD-E1TX-K

1) 9cm CST Driver for Superior Localization and Natural Sound Field Reproduction

The TAD 9cm CST driver adopted for use in the TAD-E1TX-K was designed to align the midrange and tweeter sound source positions to make the midrange diaphragm work as part of the tweeter waveguide. This design homologizes the phase and directional characteristics of midrange and tweeter sounds at the crossover, achieving natural attenuation characteristics and ideal directional patterns over the entire frequency range. The midrange-woofer crossover is set at 420Hz, in order to achieve a natural sound field and good image localization during playback. For the tweeter diaphragm, TAD has used beryllium, making optimal use of its highly rigid and lightweight properties to deliver excellent high-frequency characteristics and crystal clear sound playback. The midrange diaphragm utilizes magnesium for its high internal loss, to eliminate coloration inherent to the material and reproduce pure midrange sounds with low distortion.

2) 16cm MACC1 Diaphragm Woofer for Improved Linearity and Optimized Driving Force

In order to achieve rich, clear and faithful bass sound with no coloration, TAD has adopted a 16cm MACC1 woofer diaphragm incorporating laminated woven aramid fabric and other non-woven materials. The voice coil utilizes a highly-rigid titanium bobbin which provides high-level heat dissipation characteristics to ensure power linearity, thereby achieving faithful diaphragm response. The woofer is also equipped with LDMC2 magnet circuitry that increases the linearity of its drive and support systems. Combined with an optimized bass-reflex enclosure and powerful driving force delivered by a large ferrite magnet, this enables the woofer to reproduce clear, deep bass sounds without distortion.

2LDMC: Linear Drive Magnetic Circuit

3) Bi-Directional ADS Ports for Rich and Natural Deep Bass Sound Reproduction

The TAD-E1TX-K features slit-shaped ports located on both sides of the enclosure. Positioning horn-shaped forward and backward facing openings at the front and rear of the enclosure that lead to the ports themselves helps to drive the ports smoothly and efficiently. This design reduces port noise at high amplitude and prevents the leakage of low-order internal standing waves from the ports, eliminating the strong adverse effects of these waves on woofer-frequency sound playback and producing clear, quick response mid-low frequency range sound characteristics. The forward-backward and left-right symmetrical layout of these Bi-Directional ADS ports also cancels out forces that would vibrate the speaker enclosure, enabling deep and powerful bass sound reproduction. TAD’s existing ME1 and CE1 speakers have already been well received due to their excellent sound field reproduction over a wide range of frequencies, exceeding expectations for their size due to the inclusion of this technology. With the increased internal volumetric capacity of its floor-type design, the TAD-E1TX-K floor speaker system seeks to achieve superior sound field reproduction over an even wider range of frequencies.

Bi-Directional ADS Ports are positioned on both sides of the speaker enclosure

4) Speaker Unit Sound Source Position Alignment and Acoustic Axis Optimization

The baffle surface of the enclosure is inclined at an angle of 3 degrees in order to align the sound source positions of the CST (tweeter/midrange) and woofer units, increasing the accuracy of sound field reproduction in a floor-type double woofer system. The enclosure baffle edges are also more greatly rounded in order to reduce the effect of diffraction around the CST unit, with the acoustic axis of the CST unit installed at such an angle that it directly faces the listener. Moreover, by analyzing standing waves inside the enclosure and selecting and effectively positioning optimal sound absorption materials, it has been also reduced internal standing waves, which have an adverse effect on sound image and sound field reproduction.

5) Acoustically Isolated ISO-Mounted Network Filters

The network filters for the CST (tweeter/midrange) and woofer units are housed inside the bottom of the enclosure, and completely acoustically isolated from the main unit enclosure. This design prevents the network filters from being affected by high-level sound pressure inside the woofer and CST driver cabinets, preventing acoustic excitation of network filter elements and enabling clear and undistorted sound reproduction.

6) Machined Aluminum Baseplates Suppress Vibration and Enables Stable Installation

The bottom of the enclosure is fitted with two 15mm-thick baseplates, machined out of solid aluminum plate. Polymer resin plates sandwiched between the baseplates and the enclosure itself help to suppress vibration of the baseplates themselves, while a total of three floor spikes (two for the front baseplate and one for the rear) enables stable installation that is unaffected by the type of flooring material upon which the unit is placed. The main unit is slanted at a 3-degree angle, and the unit’s center of gravity is positioned optimally for three-point support, resulting in a structural design that solidly accepts the reaction from the woofer unit’s powerful driving force.

Main Features of the TAD-M1000-K/S Power Amplifier

1) Design Matches that of TAD-D1000 and TAD-DA1000 for Enhanced System Aesthetic

By adopting a design that matches that of the TAD-D1000 and TAD-DA1000 (launched in 2013), TAD has given the TAD-M1000-K/S a finish that is fitting of the agility, high-definition and high-level sound quality of the Evolution series. The amplifier is available in a choice of two colors—silver and black—making it easy to choose the best match for the usage environment.

TAD-D1000 / TAD-DA1000

TAD-D1000 / TAD-DA1000

2) Dual Logic-Circuit Technology for Enhanced Symmetry

The TAD-M1000-K/S adopts Dual Logic-Circuit Technology, enabling accurate driving of the speaker diaphragms by ensuring that positive and negative electric current supplies are exactly the same, and ensuring symmetry in all other respects, including circuit-type and structural aspects. The amplification circuitry adopts a BLT-type design in which two completely independent amplifiers (from the input terminals to the output terminals) are connected via a balanced connection. The power supply circuity is designed such that not only are negative and positive power supplies symmetrical, but all power supply circuit channels are independent, including power supply transformer, rectification circuitry and stabilization circuitry. In terms of structural aspects, the TAD-M1000-K/S adopts a dual mono structure which considers identicalness in terms of power transformer positioning, circuit board pattern configurations and even wiring length.

3) Vibration Control Technology

The TAD-M1000-K/S achieves isolated mounting by adopting a three-point support structure using built-in spike insulation. By clarifying load points, reducing the effect of vibrations from the floor, and enhancing isolation performance, these functions have improved the power, clarity and amount of information contained in the sound produced. It is also equipped with the same robust, high-grade, large-sized speaker terminals used in TAD’s Reference series, which serve to reduce stress on speaker cables connected to the rear side of the amplifier is rack-mounted. By improving mechanical and electrical connection stability, the TAD-M1000-K/S enables maximum effective utilization of the owner’s high-grade speaker cables.

4) High Power Usage Efficiency

The amplifier’s Class D output stage employs a power MOSFET (metal-oxide-semiconductor field-effect transistor) which eliminates lead terminals and boasts ultra-low on-resistance. This achieves high-efficiency power characteristics with power usage rates of 90% and above, conveying energy from the power supply directly to the speakers. The leadless power MOSFET offers low-loss, high-speed performance, and adopts a simple single configuration which also contributes to achieving sharper sound quality.

5) High-Capacity Power Supply

The TAD-M1000-K/S adopts a transformer-dropper type which is unaffected by switching noise, and increases the power supply’s signal-to-noise ratio. It also utilizes a 1kVA-class toroidal power supply transformer which utilizes high-quality electromagnetic steel, which helps to reduce energy-conversion loss through strong coupling between primary and secondary-side coil windings. The rectification circuitry consists of a large-capacity 33,000μF electrolytic capacitor (developed specifically for TAD) and high-speed Schottky barrier diode configuration, which helps to support the speedy and dynamic sound quality delivered by the Class D amplifier.

6) Bi-Amp Functionality

The TAD-M1000-K/S is equipped with Bi-Amp functionality which achieves improved separation characteristics, eliminating interference between units by enabling direct connection between each speaker unit and each amplifier. This enables users to take full advantage of the original true performance of both the speakers and the amplifier itself and enjoy crystal clear, undistorted sound reproduction.

Technical Audio Devices Laboratories, Inc. (TAD) introduces the Titanium Silver Micro Evolution One, expanding the color options of the world renowned Micro Evolution One, introduced autumn 2016.  The TAD-ME1-S has been crafted by TAD in a sophisticated, warm and elegant titanium silver paint polished to a high gloss mirror finish and complimented by sandstone steel side panels.  

Featuring an identical 16-cm woofer, 9cm CST1 driver and Bi-Directional ADS2 port as the original Micro Evolution One, the TAD-ME1-S produces the same accurate image localization with excellent sound field expression and resolving, natural and rich bass reproduction.

TAD will expand the product lineup of its Evolution series to respond further to customers’ needs.

1 CST: Coherent Source Transducer
2 ADS: Aero-Dynamic Slot

Main Features

1) Refined and Elegant Titanium Silver Finish

The Titanium Silver finish is created by skilled TAD artisans performing a painstaking 17 step process of paint coating, sanding and careful polishing to produce the unique and tasteful high gloss mirror finish. Artistic visual balance is obtained by TAD with a fine sandstone texture and color applied to the steel plates that constitute the side panels of the Bi-Directional ADS port. By combining different colors, textures and materials, the TAD-ME1-S exhibits a refined and tasteful appearance appropriate for the most discerning interior design.

2) 9-cm CST Driver for a Stable Localization and Natural Sound Field

TAD’s CST Driver was designed to align the midrange and tweeter sound source positions to make the midrange diaphragm work as part of the tweeter waveguide. This design homologizes the phase and directional characteristics of midrange and tweeter sounds at the crossover, achieving natural attenuation characteristics and ideal directional patterns over the entire frequency range.

For the tweeter diaphragm, TAD has consistently used beryllium for its highly rigid and extremely lightweight properties, as well as high internal loss. Its shape was configured with HSDOM 3 , an optimization technique undertaken by computer analysis, to achieve an optimum balance between a divided vibration and a piston motion. All these properties deliver ultrahigh frequency characteristics up to 60 kHz.

A magnesium midrange diaphragm is used for its high internal loss and the lightest properties among practical metals to eliminate coloration inherent in the material and reproduce pure midrange sounds with low distortion.

The CST excels in both phase and directional characteristics over a wide band from 420 Hz to 60 kHz, providing a stable localization and natural sound field.

3 HSDOM: Harmonized Synthetic Diaphragm Optimum Method

3) 16-cm MACC4 Diaphragm Woofer for Improved Linearity and Optimized Driving Force

For ideal characteristics, TAD developed a new woofer diaphragm laminated with woven and non-woven fabrics of aramid fibers. A voice coil uses a highly rigid titanium bobbin, resulting in the accurate response of the diaphragm. This provides substantial heat dissipation to ensure power linearity, contributing to the reproduction of clear bass sound and faithful low-midrange sound with no coloration.

The woofer also uses LDMC5 and a foaming polycarbonate-based urethane edge that increase the linearity of the drive and support systems. Coupled with an optimized bass-reflex enclosure, the driving force strengthened by a large ferrite magnet reproduces clear, deep bass sounds without distortion.

4 MACC: Multi-layered Aramid Composite Cone

5 LDMC: Linear Drive Magnetic Circuit

4) Bi-Directional ADS Port for Natural, Deep Bass Sounds

Originally utilized in the design of the TAD-CE1 speakers, the Bi-Directional ADS Port features slit-shaped ports located on both sides of the enclosure. These ports lead to the forward-and-backward openings and are horn-shaped to drive the port smoothly and efficiently. This design reduces port noise at high amplitude and prevents the leakage of low-order internal standing waves from the port, eliminating adverse influence on the woofer bandwidth and producing a clear, quick response mid-low frequency range sound characteristic. The bi-directional (forward-backward and left-right) layout of the port openings cancel vibration force within the enclosure, reproducing deep and powerful bass sounds.

5) SILENT6 Enclosure to Reduce Unwanted Cabinet Resonance

For high strength and low resonance, TAD uses the SILENT enclosure that combines a highly rigid birch plywood frame with an MDF (medium density fiberboard) outer panel with high internal loss. A 4 mm thick steel panel covers the left and right sides of the cabinet to further prevent unwanted resonance. TAD also analyzed internal standing waves in the enclosure to select and effectively place optimal acoustic absorbing materials, contributing to the elimination of internal standing waves, which would adversely influence the sound imaging and sound field.

6 SILENT: Structurally Inert Laminated Enclosure Technology

6) Isolated Network Filter to Minimize Interference

The design isolates the network filter assembly for CST (tweeter/midrange) and the woofer to minimize interference. The CST filter uses a PP film capacitor, a noninductive resistor, an air-core coil, and other carefully selected parts, while the 16-cm woofer filter uses a low-loss core coil with excellent magnetic properties, as well as a low-loss electrolytic capacitor, a non-inductive wire-wound resistor, an air-core coil, and other carefully selected parts, to reduce resistance caused by series insertion as much as possible. All these devices result in the reproduction of undistorted, clear sound and a fluent sound field.

Each components value was determined to optimize the acoustic output, energy, impedance, and other characteristics, providing slope characteristics that optimize the response and phase characteristics.

Inheriting the design concept of TAD’s Evolution series, the TAD-ME1-K is equipped with a new 16-cm woofer and 9-cm CST1 Driver to achieve even more outstanding sound quality throughout an entire room and extremely sharp imaging. It also incorporates TAD’s Bi-Directional ADS2 port, enabling the reproduction of natural, deep bass sound despite its compact size.

TAD will expand the product lineup of its Evolution series to respond further to customers’ needs.

Main features

1) Newly Developed 9-cm CST Driver for a Stable Localization and Natural Soundfield

TAD’s original CST Driver was designed to align the midrange and tweeter sound source positions to make the midrange diaphragm work as part of the tweeter waveguide. This design homologizes the phase and directional characteristics of midrange and tweeter sounds at the crossover, achieving natural attenuation characteristics and ideal directional patterns over the entire frequency range.

The product is equipped with the exclusively developed 9-cm CST, an optimal pairing with a 16-cm woofer. 

The crossover frequency has been set at 420 Hz for the midrange and woofer and 2.5 kHz for the midrange and tweeter.

For the tweeter diaphragm, TAD has consistently used beryllium for its highly rigid and extremely lightweight properties, as well as high internal loss. Its shape was configured with HSDOM3, an optimization technique undertaken by computer analysis, to achieve an optimum balance between a divided vibration and a piston motion. All these properties deliver ultrahigh frequency characteristics up to 60 kHz.

A magnesium midrange diaphragm is used for its high internal loss and the lightest properties among practical metals to eliminate coloration inherent in the material and reproduce pure midrange sounds with low distortion.

The new compact CST excels in both phase and directional characteristics over a wide band from 420 Hz to 60 kHz, providing a stable localization and natural soundfield.

2) 16-cm MACC4 Diaphragm Woofer for Improved Linearity and Optimized Driving Force

For ideal characteristics, TAD developed a new woofer diaphragm laminated with woven and non-woven fabrics of aramid fibers. A voice coil uses a highly rigid titanium bobbin, resulting in the accurate response of the diaphragm. This provides high radiation characteristics that ensure power linearity, contributing to the reproduction of clear bass sound and faithful low midrange sound with no coloration.

The woofer also uses LDMC5 and a foaming polycarbonate-based urethane edge that increase the linearity of the drive and support systems. Coupled with an optimized bass-reflex enclosure, the driving force strengthened by a large ferrite magnet reproduces clear, deep bass sounds without distortion.

3) Bi-Directional ADS Port for Natural, Deep Bass Sounds

A slit-shaped port is located on both sides of the enclosure, which was proven in the TAD-CE1 speakers of the Evolution series. The parts leading to the forward-and-backward openings are horn-shaped to drive the port smoothly and efficiently. This design reduces port noise at high amplitude and prevents the leakage of low-dimensional internal standing waves from the port, which would have a major impact on the woofer bandwidth, to achieve a responsive, clear low midrange sound. The bi-directional (forward-backward and left-right) layout of the port openings offsets vibration force to the enclosure, reproducing deep, powerful bass sounds. 

4) SILENT6 Enclosure to Reduce Unwanted Cabinet Resonance

For high strength and low resonance, TAD uses the SILENT enclosure that combines a highly rigid birch plywood frame with an MDF (medium density fiberboard) outer panel with high internal loss. A 4 mm thick steel panel covers the left and right sides of the cabinet to further prevent unwanted resonance. TAD also analyzed internal standing waves in the enclosure to select and effectively place optimal acoustic materials, contributing to the elimination of internal standing waves, which would adversely influence the sound imaging and soundfield.

5) Sharp, Beautiful Piano Black Finish

A minimal baffle is used to minimize sound refraction, while the enclosure is finished in a refined piano black coating. Skilled artisans devote time and pay careful attention to the details in the process of spray coating, primary coat polishing, and final polishing.

A steel panel that makes up the Bi-Directional ADS port on the sides is adorned with a new design featuring fine-grained coating.

6) Mounted Isolated Network Filter to Minimize Interference

The design isolates the network filter assay for CST (tweeter/midrange) and the woofer to minimize interference. The CST filter uses a PP film capacitor, a noninductive resistor, an air-core coil, and other carefully selected parts, while the 16-cm woofer filter uses a low-loss core coil with excellent magnetic properties, as well as a low-loss electrolytic capacitor, a noninductive wire-wound resistor, an air-core coil, and other carefully selected parts, to reduce resistance caused by series insertion as much as possible. All these devices result in the reproduction of undistorted, clear sound and a fluent soundfield.

Each constant was determined to optimize the acoustic output, energy, impedance, and other characteristics, providing slope characteristics that optimize the response and phase characteristics.
