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-E1TX-K

TAD Launches Evolution Series Floor Speaker and Power Amplifier

Further Enhanced TAD Evolution Series Technology

TAD-E1TX-K
TAD-M1000-K/S

TAD-M1000-K / TAD-M1000-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

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.

TAD Introduces Titanium Silver Micro Evolution One

Expansion of Color Options

TAD-ME1-S

TAD-ME1-S_Chart.jpg

Design concept

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.

"These TAD Micro Evolution ONEs ($12,495) had some of the best tactility I’ve heard at the show. It’s definitely the kind of sound that sings to me emotionally and has me slowly pulling out my wallet. Jonathan Derda from Mofi was describing the very interesting cabinet design which allows it to produce an enormous amount of low-end that competes with much larger floorstanders. One of my favorites from the show and one of the few speakers I revisited during my 3-day visit."

"...TAD Laboratories Micro Evolution One ($12.5k) we saw at AXPONA this year. During that demo, MoFi’s Jon Derda gave us a sample of Led Zepplin’s “Moby Dick” that we won’t soon forget. Even with the older production tech used during that time period, John Bonham’s drum solo felt shockingly tight, with left/right imaging that might make a hardcore fan’s hair raise. The TAD One managed to overcome the bass extension hurdle that so many bookshelf category struggle with, on both then and this weekend. ...the Micro finds its appeal as a natural extension to the detailed groundwork both these speakers lay out in the market. The TAD’s are rated down to 36Hz from the 16cm woofer cone. Sure, adding a sub might make your teeth rattle a bit more, but in most 2 channel music situations, it hasn’t been very noticeable – which is saying a lot without boasting anything at all."

PRESS RELEASE

                 Combination of TAD-ME1-K and TAD-ST3-K

TAD Introduces Compact Bookshelf-Type Speaker

Micro Evolution One

TAD-ME1

Design concept

Technical Audio Devices Laboratories, Inc. (TAD) will introduce the compact bookshelf-type speaker system Micro Evolution One TAD-ME1-K, further perfecting TAD’s sound concepts of high-dimensional sound imaging and soundfield immersion. 

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.

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

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.

3 HSDOM: Harmonized Synthetic Diaphragm Optimum Method

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.

4 MACC: Multi-layered Aramid Composite Cone
5 LDMC: Linear Drive Magnetic Circuit

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.

6 SILENT: Structurally Inert Laminated Enclosure Technology

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.
