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.

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.

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.
