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 Grand Evolution One Features
TAD-GE1 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 unit is equipped with a coaxial speaker unit “CST driver”
that reproduces controlled directivity over a wide bandwidth
from a phase-matched point, reproducing stable localization
and a natural sound field space. The cone shape of the
midrange is designed to control the directivity of the coaxially
placed tweeter, and by matching the phase and directivity
characteristics of the tweeter and midrange crossover, a
natural attenuation characteristic and directional radiation
pattern are achieved over the entire bandwidth, making the
CST driver alone capable of ultra-wideband reproduction
from 250 Hz to 100 kHz. The CST driver is mounted in a low-
diffraction shaped enclosure to maximize its performance.
Furthermore, ISO (Isolation) drive technology reduces
vibration transmission from the CST driver to the enclosure,
enabling the reproduction of a clear, uncluttered airy sound.
2. Beryllium tweeter and magnesium midrange
diaphragms
The tweeter features a light-weight, highly rigid beryllium
diaphragm. Utilizing our proprietary vapor-deposition process.
The combination of stiffness, low mass, and high internal
damping ensures that the diaphragm resonances are well
controlled and placed well above the range of audibilty.
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. Adoption of MACS II*2 diaphragm in the woofer
The woofer adopts a MACS diaphragm laminated with
multiple layers of lightweight and highly rigid aramid fiber
and the center cap and cone are integrated into a shell shape
to achieve a rich bass sound reproduction and clear mid-low
frequency reproduction.
4. “SILENT*3 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*4is employed to analyze
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. “Bidirectional ADP*5 System”
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.

INSTALLATION AND CARE
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 auxiliary feet 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.
Precautions regarding the
installation location
Avoid environments with high humidity, excessive
dryness, rapid temperature changes, and strong
ultraviolet rays.
Such conditions may result in shrinkage of the wood
materials and finish, leading to deformation of the
enclosure, discoloration, or damage to the speakers.
Avoid installing this unit in the following locations:
'Places exposed to direct sunlight
'Places near heating devices
'Places directly under an air conditioner or where the
unit is exposed directly to blowing air
'Places with poor ventilation and a lot of humidity and dust
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)
Precautions during
installation
'The total weight of this speaker system is 64kg (141.1 lb).
Before installing, confirm that the installation location is
fully capable of supporting this weight
'As the weight of this speaker system is 64kg (141.1 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 21kg(46.3 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 auxiliary feet before moving the speaker
system.

below.
How to install: Install the woofer grille so that the magnets are
positioned as shown in the figure below.
How to remove: Pull the grille toward you to remove it as shown in
the figure below.
Please remove the woofer grille when using or cleaning this
speaker system. Also, if you apply horizontal force while it is
attached, the grille may fall.
Installation of Spikes
Caution
Please be sure to screw all the way in when installing spikes.
The installation surface can be securely established by using
spikes.
Spikes are screwed into three aluminum base screw holes at the
bottom of the cabinet.
Installation can be performed with no rattling of the installation
surface and requiring no fine adjustment of spike heights, by
providing support at three locations.
Once the installation location is decided by referencing the
section about Choosing Where To Place The Speakers on page 7,
install the spikes and the auxiliary feet.
Auxiliaryfeet
1. Screw in spikes at three locations on the bottom surface of the
aluminum base (two in front and one in back).
2. Install the auxiliary feet at the two rear locations, adjust the
length of the spikes so that they do not rattle, and tighten them
with nuts.
3. Place spike receivers at locations where spikes will be
positioned, then place the speaker on top of the spike receivers.
・
Place the speaker on top of something that would
not scratch it, such as a soft cloth, to perform
installation of the spikes.
・
Place spike receivers with the center indentation
facing up, as shown in the diagram below.
・
Using spikes without using spike receivers can
potentially leave scratches on the surface where the
speaker is installed, such as the surface of the floor.

Choosing Where To Place The Speakers
Speaker placement within the listening room will have a great impact upon the total performance of the unit in terms of bass performance,
tonal accuracy, and imaging. All rooms are different and so this section is intended as a guide only. Experimentation in your room will yield
optimum results.
Begin by placing the rear of the speakers approximately one to two feet in from the front walls and the sides one to two feet in from the
side walls of your listening room, as shown in Figure 1. Your listening position should be roughly equal to the distance between the two
speakers. Also, turn the speakers inward so each axis points toward the listening position.
Next, connect the audio system as described in CONNECTING THE SPEAKERS on page 8. Then, optimize the speaker placement as
described in OPTIMIZING THE SYSTEM on page 12.

Speaker care
The TAD Grand Evolution One speaker system has a meticulous mirror finish. If the enclosure collects dust or fingerprints, wipe them off
with the cleaning cloth provided.
CAUTION
'When dusting the cabinet, do not use cleansers, abrasives or chemically impregnated cloths.
'Contact with alcohol, benzene, insecticides or other chemicals may cause peeling or discoloration of the finished surface.

CAUTION
'When connecting speakers or other components, always turn off the power to the amplifier, and disconnect the power cord.
'Speaker cables are not furnished with this speaker system, and must be purchased separately.
'After connecting the speakers, gently pull on the speaker cables to confirm that each cable wire is connected securely to its
respective terminal. Loose connections may result in interrupted sound or noise.
'Do not allow wires from one connector or cable to touch those from another, since excessive load may be applied to the
amplifier, causing the amplifier to stop operating or be damaged.
'If the polarity (+/−) of either right or left speaker is mistakenly reversed when connected to the amplifier, the speakers will
be unable to produce proper stereo phase effect.
Input terminal specifications
This speaker system is provided with LF (Low-Frequency) input terminals for the woofer, and HF (High-Frequency) input terminals for CST
(Coherent Source Transducer) connections.
Single-Wire Connections
When adopting single-wire connections, use the furnished accessory shorting links to connect the LF input terminals (for woofer) to the HF
input terminals (for CST).
Use the shorting links to connect the upper/lower HF input terminals to the upper/lower LF input terminals as shown in Figure 2, then
connect the positive (+) speaker wire from the amplifier to either of the speaker’s red connector terminals, and the negative (−) speaker
wire from the amplifier to either of the speaker’s black connector terminals..

Bi-Wire Connections
When adopting bi-wire connections, the speaker cables from the amplifier are connected individually to the LF input terminals (for woofer)
and the HF input terminals (for CST).
Connect one set of speaker cables to the LF input terminals (for woofer). Then, connect the other set of speaker cables to the HF input
terminals (for CST). Finally, connect the respective speaker cables in pairs to the amplifier’s speaker terminals.
Take care to connect both (+) wires to the (+) amplifier terminals and both (–) wires to the (–) amplifier terminals, as shown in Figure 3.

Bi-Amplification Connections
When using a bi-amp configuration, a dedicated amplifier is connected to the LF input terminals (for woofer) and HF input terminals (for
CST). Two connection methods are possible, the “vertical bi-amp” method and “horizontal bi-amp” method.
WARNING
• Remove the shorting links before connecting speaker cables in bi-amplification connections. Failure to do so may result in
damage to your amplifiers.
Vertical Bi-Amping
With this configuration, identical stereo amplifiers are used for each speaker. One channel of each amplifier drives the low frequency
section and the other channel drives the high frequency section, as shown in Figure 4. Connect one set of speaker cables between the
amplifier’s Channel 2 (or 1) terminals and the speaker’s LF input terminals (for woofer). Then connect another set of speaker cables
between the amplifier’s Channel 1 (or 2) terminals and the speaker’s HF input terminals (for CST).
Take care to connect both (+) wires to the (+) amplifier terminals and both (–) wires to the (–) amplifier terminals.

Horizontal Bi-Amping
With this connection method, independent stereo amplifiers are used respectively to drive the speaker’s LF circuit (for woofer) and HF
circuit (for CST).
As shown in Figure 5, each channel on one of the amplifiers is used to drive the speakers’ low-frequency range, while each channel of the
other amplifier is used to drive the high-frequency range of the two speakers.
In order to use this method, each of the amplifiers must possess the same gain value. If the two amplifiers have different gain values,
an imbalance will occur between the playback levels of the low-frequency and high-frequency ranges. Consult your dealer for further
information.

Improving Bass Performance
Select a music track with well-recorded bass, such as acoustic
string bass. Listen for all the bass notes having roughly equal
level. If any notes jump out at you more strongly than others, try
moving the TAD Grand Evolution One speaker system until you
get the most even progression of the notes.
Typically, moving them towards the walls will increase low
bass output, but can result in more unevenness higher up the
musical scale. Moving them closer to the side walls will not
produce the same effect as moving closer to the back wall, so try
experimenting moving both ways for the most pleasing sound.
Also listen to drum sounds. The kick drum should sound tight and
fast, without low-frequency boom. Changes in speaker position
of as little as a few inches can have a large effect upon bass
performance, so take time and try many positions.
A useful tip to speed up the process is to have a partner move
around the room while talking. Listen to where the voice sounds
most natural, without added chestiness, and position the speaker
system in that location.
Improving Imaging
Now select music with a strong center image. Listen for that
image to be exactly centered between the speakers, and to be
well-focused. If the image is unclear and spreads wide, the side
walls are probably creating strong reflections. Try moving the
speakers closer together to reduce this effect. If this brings them
too close, try instead toeing in the speakers so that the axis
crosses in front of the listening position. Because of the superior
off-axis performance of the CST driver, the strength of the sidewall
reflections will be reduced, and at the same time, the image will
be stabilized and focused.
Now listen to music with well-recorded acoustics. Check that the
image is wide and deep. Limited depth suggests that the speakers
are placed too close to the front wall. Try moving them forward.
OPTIMIZING THE SYSTEM
Final Optimization
You may find that as you move the speakers to optimize one
aspect of performance another worsens; for example, trading
improved image accuracy for poorer bass response. If this occurs,
try moving your listening position. Bass response is governed
strongly by both speaker and listening positions, whereas imaging
is mostly determined by the speaker position. Therefore, you
may find that if optimizing for imaging compromises bass, then
changing the listening position will bring back bass performance.
The room characteristics will also have a profound influence
upon the sound. Live rooms, with few soft furnishings and hard
floors, will impart an artificial sense of spaciousness to the sound
but reduce the intimacy and accuracy. Overly dead rooms, with
lots of furnishing, carpets, and drapes will produce a very dry,
lifeless sound and require lots more power to drive the speaker
system to adequate sound levels. The optimum is somewhere
inbetween. Avoid hard, unbroken, parallel walls, especially side
walls, as these impart strong flutter-type echoes and will have a
bad influence on the imaging. Try and break up long expanses of
walls with drapes, wall hangings, or bookshelves, and try not to
introduce too much asymmetry into the room layout, as this will
also affect the imaging.

The Safety of Your Ears is in Your Hands
Get the most out of your equipment by playing it at a
safe level – a level that lets the sound come through
clearly without annoying blaring or distortion and, most
importantly
, without affecting your sensitive hearing.
Sound can be deceiving. Over time, your hearing
“comfort level” adapts to higher volumes of sound, so
what sounds “normal” can actually be loud and
harmful to your hearing. Guard against this by setting
your equipment at a safe level BEFORE your hearing
adapts
.
EST
ABLISH A SAFE LEVEL:
•
Set your volume control at a low setting.
•
Slowly increase the sound until you can hear it
comfortably and clearly, without distortion.
•
Once you have established a comfortable sound
level, set the dial and leave it there.
BE SURE TO OBSER
VE THE FOLLOWING
GUIDELINES:
•
Do not turn up the volume so high that you can’t
hear what’s around you.
•
Use caution or temporarily discontinue use in
potentially hazardous situations.
•
Do not use headphones while operating a motorized
vehicle; the use of headphones may create a traffic
hazard and is illegal in many areas.

une localisation stable et un champ sonore naturel. La forme
conique du haut-parleur médial est conçue pour contrôler la
directivité du tweeter coaxial placé, et en faisant correspondre
les caractéristiques de phase et de directivité du tweeter
et du crossover médial, une caractéristique d’atténuation
naturelle et un profil de rayonnement directionnel sont
atteints sur toute la bande passante, ce qui rend le pilote
CST seul capable de reproduire l’ultra-large bande de 250 Hz
à 100 kHz. Le pilote CST est monté dans un boîtier en forme
de faible diffraction pour maximiser ses performances. De
plus, la technologie d’entraînement ISO (Isolation) réduit
la transmission des vibrations du pilote CST vers le boîtier,
permettant la reproduction d’un son clair et épuré.
INTRODUCTION
2. Tweeter en béryllium et diaphragmes médium
en magnésium
Le tweeter se caractérise par son diaphragme léger et très
rigide en béryllium. Utilisation de notre procédé de dépot en
phase vapeur. L’association de rigidité, de légèreté et d’un
fort amortissement interne garantit que les résonances du
diaphragme sont bien contrôlées et placées bien au-dessus
de la plage d’audibilité. Du magnésium est utilisé pour le
diaphragme du médium. La combinaison de rigidité, de
légèreté et de durabilité fait en sorte que la plage du médium
est restitutée en étant exempte de résonance et de distortion.
3. Adoption du diaphragme MACS II*2 dans le
haut-parleur de graves
Le haut-parleur de graves utilise un diaphragme MACS
stratifié avec de plusieurs couches de fibre d’aramide
légère et très rigide et le couvercle central et le cône sont
intégrés dans une forme de coque de manière à obtenir une
reproduction sonore riche basse et une reproduction claire à
moyenne-basse fréquence.
4. “Boitier SILENT*3” pour faible résonance
L’enceinte utilise un boîtier SILENT qui atteint une résistance
élevée et une faible résonance avec la combinaison d’un
contreplaqué de bouleau à haute rigidité pour le cadre et des
matériaux MDF pour une perte interne élevée. De plus, AFAST*4
est utilisé pour analyser les ondes stationnaires à l’intérieur
de l’enceinte et réduire les modes d’ordre faible. Les ondes
stationnaires internes, qui ont un impact négatif sur l’image
sonore et sur le champ sonore, peuvent être supprimées en
sélectionnant et en arrangeant efficacement les matériaux
d’absorption acoustique optimaux.
5. Système Bidirectional ADP*5
Un port pour le fonctionnement bass-reflex est situé au bas
de l’enceinte. Des ouvertures en forme de corne à l’avant
et à l’arrière, composées d’une plaque de base de 15 mm
d’épaisseur, le fond de l’enceinte et une plaque de corne en
aluminium moulé sous pression, offrent une reproduction
sonore naturelle et riche des basses.

INSTALLATION ET SOINS
Installation
Installation sur le plancher ou dans un rack
Une plaque en aluminium est fixée au fond du boîtier du système
d’enceintes. Lorsque le sol est plat, il peut être installé tel
quel. De plus, la pointe, les réceptacles de pointes et les pieds
auxiliaires sont fixés au système de haut-parleurs et, ainsi, la
méthode d’installation la plus appropriée suivant l’état de la
surface d’installation peut être choisie. Choisissez la méthode
d’installation en vous reportant au point suivant.
Pointe Lieu d’installation Utilisation
Pointe conique
28 mm
Sol revêtu de
moquette sans
rayures ou lieu où
les rayures sont
permises
Utilisez-la en enfonçant
une pointe dans la
moquette.
Surface plane Pour éviter les rayures sur
la surface d’installation,
utilisez le réceptacle de
pointe fourni.
Ne pas utiliser de
pointe
Surface plane Prévoyez un élément
antidérapant et posez-le
sur le sol.
Précautions relatives à l’endroit
d’installation
Évitez les environnements à humidité élevée, la
sécheresse excessive, les changements de température
brusques et les rayons ultraviolets forts. Un tel endroit
pourrait provoquer une contraction des parties en bois
et de la finition, entraînant une déformation du coffret,
sa décoloration ou des dégâts aux haut-parleurs.
Évitez d’installer ce dispositif dans les lieux suivants :
'Les endroits exposés à la lumière directe du soleil
'Près d’appareils de chauffage
'Directement sous un climatiseur où dans un lieu où
l’appareil est exposé directement à une soufflerie d’air
'Les lieux mal aérés envahis par l’humidité et la poussière
Des situations considérées comme désagréables pour
les êtres humains seront nuisibles également pour les
enceintes. Fournir aux enceintes un environnement
confortable leur permettra de déployer leurs meilleures
performances. Essayez de maintenir l’environnement
suivant lors du fonctionnement :
Température : de 15 °C à 25 °C
Humidité relative : de 35 % à 65 % (hiver)
de 40 % à 70 % (été)
Précautions pendant
l’installation
'Le poids total de cette enceinte est de 64 kg. Avant
de l’installer, assurez-vous que l’endroit est capable
de supporter un tel poids.
'Dans la mesure où ce système d’enceintes pèse 64 kg,
2 personnes ou plus doivent installer la pointe en
l’inclinant. Lors de l’installation, faites attention à ne
pas vous pincer les doigts avec le système d’enceintes et
assurez-vous que le système d’enceintes ne tombe pas.
'Evitez de toucher la face avant des haut-parleurs,
car vous pourriez déformer ou endommager leur
matériau à mailles ou leur diaphragme.
'De plus, lorsqu’une pointe est utilisée, une charge
de 21 kg ou plus est appliquée par pointe, des traces
ou des bosses peuvent donc subsister à l’endroit où
le système d’enceintes a été installé. Pour éviter les
rayures, utilisez le réceptacle de pointe fourni ou
prévoyez un réceptacle de pointe de remplacement
suffisamment robuste avec une grande zone
d’installation par pointe.
'L’utilisation d’une pointe dans le système de haut-
parleurs peut provoquer des rayures sur le sol durant
le déplacement, retirez donc la pointe etles pieds
auxiliaires avant de déplacer le système de haut-
parleurs.
