INTRODUCTION

Inspiring the joy of listening

Technical Audio Devices Laboratories, Inc. (TADL) grew from
the spirit to discover technologies to perfectly recreate the pure
sound of life performances with uncompromising craftsmanship.
We have inherited our philosophy from Bart Locanthi –recognized
across the globe as the ultimate sound technologist–who
believed that genuine technology is true to the basic and that
genuine technology places greater importance on sound quality
than on technology for its own sake. At TADL, we are honing our
technology to create equipment that reproduces musical sounds
that evoke both the energy and impact of life music.

TAD Evolution One Features

TAD-E1AX is the speaker system by using the accumulated
acoustic technology in TAD's past history and advanced
audio technology in order to realize the emotional sound.
1. Coaxial speaker unit with "CST
The heart of the system is the Coherent Source Transducer
(CST). The tweeter diaphragm is mounted concentrically
within the midrange cone and provides a point source of
sound from 420 Hz to 60 kHz. It results in creating both time
coherency and matched directivity between the midrange
and tweeter, producing superbly-controlled radiation patterns
and ensuring a perfect spectral balance between the direct
and reflected sounds arriving at the listener's ears. The result
is more consistent sound throughout the listening room and
improved imaging capability. By mounting this unit in the
perfectly shaped enclosure, the CST driver is provided with
optimum conditions for producing the utmost in performance.
2. Beryllium tweeter and magnesium midrange
diaphragms
The tweeter features a light-weight, highly rigid beryllium
diaphragm. Using a uniquely developed vapor deposition
method, internal loss is greatly increased, thereby achieving
excellent high-frequency resonance damping characteristics.
Ultra-smooth features have been achieved with its semi-
dome shape using HSDOM*
midrange diaphragm to eliminate the influence of material-
specific resonance and reproduce sound with minimal
distortion.

3. Woofer designed with MACC
The woofer adopts a newly developed MACC diaphragm made
of bonded woven and nonwoven fabric of highly lightweight
and firm aramid fiber. This enables to realize a rich low-pitch
and clear mid-range audio frequency reproduction.

4. "SILENT Enclosure" for low resonance
The cabinet uses a SILENT enclosure that achieves high
strength and low resonance by combining high-rigidity
birch plywood for the framework and MDF materials for high
internal loss. In addition, AFAST*
standing waves inside the enclosure and reduce low-order
modes. Internal standing waves, which have a negative
impact on the sound image and sound field, are suppressed
by selecting and effectively arranging the optimal sound-
absorbing materials.
5. Adopted "Bidirectional ADP
A port for bass-reflex operation is located at the bottom of
the enclosure. Horn-shaped openings in the front and rear,
consisting of a 15mm-thick base plate, the bottom of the
enclosure, and a horn plate made of die-cast aluminum,
provide natural and rich bass sound reproduction.
