BEFORE YOU START
Thank you for buying this TAD product. Please read through
these operating instructions so you will know how to operate your
model properly. After you have finished reading the instructions,
put them away in a safe place for future reference.
This speaker system has an impedance of 4 ohms, and
should be connected only to an amplifier designed with a
load impedance of 4 ohms (the amplifier’s speaker output
connector should clearly be labeled “4 ohms”).
In order to prevent damage to the speaker system resulting from
input overload, please observe the following precautions:
Do not supply power to the speaker system in excess of the
maximum permissible input.
Always turn off the amplifier power whenever connecting this
unit or other components to the amplifier.
Be careful not to overload the amplifier by playing at high
sound levels, as the amplifier’s harmonic distortion will be
increased and you may damage the speaker.
Caution: installation
Do not place the speaker on an unstable surface. It could
present a hazard if it falls, as well as potentially damaging the
equipment.
Do not attach these speakers to the wall or ceiling. They may
fall off and cause injury.
Switch off and unplug your AV equipment and consult the
instructions when connecting up components. Make sure you
use the correct connecting cables.
Technical Audio Devices, Inc. is not responsible for any
accidents or damage that result from improper installation,
misuse or modification of the product, or natural disasters.
Caution: in use
Do not allow the speaker to output distorted sound for long
periods of times. This is an indication of using excessive power
and can result in a fire hazard.
Do not sit or stand on the speaker, or let children play on the
speaker.
Do not put any objects on top of the speaker.
Do not place magnetic objects such as screwdrivers or iron
parts near the tweeter or midrange. Since the speakers use
strong magnets, the objects may be attracted, causing injury
or damaging the diaphragm.

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.
INTRODUCTION
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.

Installation
Installation on floor or rack
An aluminum plate is fixed at the bottom of the cabinet of
speaker system. When the floor is flat, it can be installed as it is.
Moreover, spike, spike receptacle and overturn preventing spike
are attached to the speaker system and hence the most suitable
installation method according to the status of installation surface
can be selected. Decide the installation method by referring to the
following matter.
Spike Installation place How to use
Cone shaped spike
28 mm
A carpeted floor
with no scratches
or the place where
scratches are
allowed
Use by pushing a spike
into the carpet.

Flat place To avoid scratches on
the installation surface,
use the supplied spike
receptacle.
Do not use spike Flat place Arrange a non-slippery
sheet and lay it on the
floor.
INSTALLATION AND CARE
Precautions regarding the
installation location
Do not install the speaker system in areas exposed
to direct sunlight nor near heating appliances. Such
conditions may result in shrinkage of the wood materials
and finish, leading to deformation of the enclosure,
discoloration, or damage to the speakers.
Conditions considered unpleasant by humans are
detrimental to speakers as well. Providing a comfortable
environment for the speakers will assist them in
demonstrating their best performance. Please maintain
the usage environment as follows:
Temperature: 15 °C to 25 °C (59 °F to 77 °F)
Relative Humidity: 35 % to 65 % (winter)
40 % to 70 % (summer)
When using room air-conditioners or stoves to rapidly
cool or heat room spaces, take precautions to avoid
excessive dehumidification.
Avoid placing the speaker near areas such as windows,
as outside air can cause condensation to occur within
the speaker.
Precautions during
installation
The total weight of this speaker system is 46kg (101 lb).
Before installing, confirm that the installation location is
fully capable of supporting this weight
As the weight of this speaker system is 46kg (101 lb),
2 or more persons should install the spike when
installing it by tilting. At the time of installing, take
care not to pinch fingers between the speaker system
and see that speaker system does not fall.
Avoid touching the front surface of speaker units,
since you may deform or damage the enclosure mesh
or speaker diaphragms.
Moreover, when spike is used, a load of 15kg(33 lb)
or more is applied per spike and hence traces or dents
may remain at a place where the speaker system has
been installed. To avoid scratches, use supplied spike
receptacle or arrange strong enough standby spike
receptacle with large installation area per spike.
Using a spike in the speaker system may cause
scratches on the floor while moving it, so remove the
spike and overturn preventing spike before moving
the speaker system.
