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-E1TX Features
TAD-E1TX 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
*1
driver”
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. Ultra-smooth features have been achieved with
its semi-dome shape using HSDOM*
2
. Magnesium is utilized
for the midrange diaphragm. It’s combination of stiffness,
low mass and durability ensure that the midrange is similarly
reproduced with freedom from resonace and distortion.

3. Woofer designed with MACC
*3
diaphragm
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
*4
Enclosure” for low resonance
The cabinet is constructed of high-rigidity Baltic birch plywood
combined with MDF for high internal loss, achieving a “SILENT
Enclosure” that combines high strength with low resonance.
In addition, it is sandwiched from left to right by a highly
dense and extremely strong, 4 mm thick structural steel plate
to reduce the unnecessary resonance from the cabinet.
5. “Bi-Directional ADS
*5
port”
The bass reflex port has been integrated into the enclosure
side of the speaker. The port opening is designed as horn-
shaped slits located front-back and right-left, allowing the
speaker to reproduce natural and luxuriant low-frequency
sound. By eliminating unnecessary noise from the port and
the influence of internal standing waves, the speaker produces
clear bass sound with excellent response.
