TAD Evolution E1TX

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.

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.

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.
