TAD EVOLUTION ONETAD-E1TX
The Art of Sound
The fusion of physical beauty
and full-range acoustic artistry.
The long-awaited Evolution series floor type speaker system equipped with CST and Bi-Directional ADS port was born. Speakers that reproduce smooth bass by Double Woofer and ADS and realize natural sound spreading in wide frequency band by CST will produce glittery and sophisticated space with beautiful form.







TECHNOLOGY
CST Driver

Sound with all its original brilliance
The E1TX adopts TAD’s micro CST* Driver, designed
exclusively to deliver a truly natural sound. This
9cm micro driver was originally implemented in the
critically acclaimed TAD Micro Evolution One
series.
As with all TAD CST drivers, the
precision-designed midrange and tweeter are
positioned coaxially for optimal directional
characteristics with minimal audio interference,
each complimenting the other’s respective output
and successfully achieving the point sound source
concept.
Lightweight yet highly rigid
beryllium is utilized for the tweeter diaphragm,
contributing to the CST driver’s ability to
deliver superb and stable localization of sound
with natural sound field reproduction over its
broad frequency band from 420Hz to 60kHz.
* CST: Coherent Source Transducer
BASS Driver

Captivating midrange and precise bass extension
Twin 16cm woofers feature TAD’s proven MACC*
Diaphragm combined with a powerful magnetic
circuit to achieve outstanding drive linearity for
superior midrange response and excellent bass
extension.
The unique construction of the
MACC Diaphragm is composed of layers of aramid
fabric and raw fibers formed individually, then
laminated to form a single composite cone.
The result is a diaphragm with enhanced
strength, improved internal loss characteristics
and ideal vibrational behavior that produces rich,
smooth midrange and deep bass free from coloration
and distortion.
* MACC: Multi-Layered Aramid Composite Cone
Enclosure

Bass foundation developed through advanced engineering and art
First introduced in TAD’s Compact Evolution One,
the Bi-Directional ADS* Port is an innovative
approach to achieving powerful bass reproduction.
Applied for the first time in a floor
standing, full-range design, the unique
Slit-shaped ports of the E1TX are positioned low
and near the floor for the standing wave leakage
reduction and the natural bass reproduction, and
exist both the left and right sides with circular
shaped flared openings to the front and rear of
the enclosure.
This symmetrical front-back,
left-right layout combined with the low, offset
slot location eliminates unwanted sound from the
port and reduces standing waves within the
enclosure.
Combined with the organic,
compound shape of the beautifully finished
cabinet, the E1TX is an acoustic and visual work
of art, capable of reproducing a rich and powerful
sound field that will fill your room and your
senses.
