Description

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 Labs 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.

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.

The TAD 9cm CST driver adopted for use in the TAD-E1TX-K was designed to align the mid-range and tweeter sound source positions to make the mid-range diaphragm work as part of the tweeter wave-guide. This design homologizes the phase and directional characteristics of mid-range and tweeter sounds at the crossover, achieving natural attenuation characteristics and ideal directional patterns over the entire frequency range. The mid-range-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 labs 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 mid-range diaphragm utilizes magnesium for its high internal loss, to eliminate coloration inherent to the material and reproduce pure mid-range sounds with low distortion.

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.

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/mid-range) 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.

 

The network filters for the CST (tweeter/mid-range) 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.

 

The bottom of the enclosure is fitted with two 15mm-thick base-plates, machined out of solid aluminum plate. Polymer resin plates sandwiched between the base-plates and the enclosure itself help to suppress vibration of the base-plates themselves, while a total of three floor spikes (two for the front base-plate 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.
