INTRODUCTION  
TAD History  
TAD Reference One Description  
Founded in 1975, Technical Audio Devices (TAD)  
has continued to stand at the frontier of cutting-edge  
sound technology, maintaining a well-established  
tradition of creating high performance speakers for  
professional use. TAD products are designed, crafted,  
and produced with strict adherence to the most  
rigorous standards demanded by musicians and  
professional audio-system designers around the world.  
The TAD Reference One loudspeaker is a  
breakthrough product for the home audio market,  
and represents the culmination of over 30 years  
experience in developing class-leading loudspeakers  
for the professional studio monitoring environment.  
Central to the performance of the TAD Reference  
One loudspeaker is the Coherent Source Transducer  
(CST), a concentric unit featuring TAD’s unique  
beryllium-diaphragm design. Beryllium is used for  
both the tweeter dome and the midrange cone, to  
provide a point source radiator covering the frequency  
range from 250 Hz to 100 kHz.  
TAD loudspeaker components are found in studio  
monitors, sound reinforcement systems, public  
address and concert hall speakers, cinema theater  
audio systems, and many other applications that  
require the highest-quality sound reproduction.  
The CST is supplemented by dual 25 cm (10 in.) bass  
drivers enclosed in structurally inert cabinet. The  
result is a very wide-band, resonance-free monitor  
loudspeaker of the highest quality.  
With this high standard of quality, world-class  
recording studios rely on TAD components for  
original recordings and digital remastering of audio  
performances. In recent years, TAD has met the  
demand for high-quality home audio speakers by  
delivering world class audio components that carry the  
TAD pedigree into the home.

TECHNOLOGY  
Beryllium Diaphragms  
CST  
Each TAD Reference One loudspeaker features  
proprietary beryllium-manufacturing technology for  
the midrange and tweeter diaphragms. The lightest  
and most rigid metal available for diaphragms,  
beryllium performs with strength and damping  
characteristics unmatched by any of the materials  
currently used in high-end audio loudspeaker  
manufacturing, as shown in Figure 1. Beryllium’s  
combination of light weight and exceptional strength  
enables diaphragm resonance to be pushed far beyond  
the operating band of its drive units. This produces  
near-perfect piston behavior in the speakers, resulting  
in cleaner sound and greater accuracy of reproduction.  
The heart of the system is the Coherent Source  
Transducer (CST), shown in Figure 2. The tweeter  
diaphragm is mounted concentrically within the apex  
of the midrange cone and provides a point source of  
sound from 250 Hz to 100 kHz. It is time coherent,  
due to the shallow midrange-cone profile made  
possible by the superior strength of beryllium, and  
producesasuperbly-controlledradiationpattern. CST  
ensures a perfect spectral balance between the direct  
and reflected sounds that arrive at the listener’s ears,  
providing a more consistent sound throughout the  
listening room and improved imaging capability.

Bass Drivers  
The foundation of the TAD Reference One  
loudspeaker is the bass drivers, as shown in Figure 3.  
The driver cones are constructed from a tri-laminate of  
front and rear-woven aramid fibers that sandwich a  
foamed acrylic core. This provides enormous strength  
to the cone in order to resist any flexing due to the  
high forces exerted during loud bass passages.  
To achieve high drive linearity, the motor structure  
employs short coil and long gap geometry, Faraday  
shorting rings, and a novel flux path for even lower  
distortion. Combined with advanced spider and  
multi-roll surround design, the bass driver has over 30  
mm (1.25 in.) of linear drive capability, as shown in  
Figure 4.

CST Mounting Construction  
Crossover Networks  
The CST driver is mounted into an extremely firm  
enclosure that features a headboard specially formed to  
optimize the sound emitted from the driver. To  
further enhance the performance, ISO-Drive  
technology is used to mechanically isolate the CST  
driver from its mounting. This greatly reduces the  
mechanical energy that is the source for enclosure  
vibration, resulting in reduced delayed resonances and  
improved resolution of fine detail.  
The crossover networks use only the finest  
components. Air cored coils, noninductive resistors,  
and film capacitors in the signal path are all carefully  
chosen and optimized for the CST driver to provide  
the greatest transparency to the signal. The bass drivers  
use laminated steel-core inductors for highpower  
handling and low saturation. All components are built  
on high-grade, glass-epoxy, printed circuit boards with  
thick copper traces to ensure stability and repeatability  
of performance.  
Bass Enclosure Construction  
Enclosure Finish  
The enclosure of the TAD Reference One's bass  
drivers features a frame of 21 mm (0.9 in.) thick  
laminated birch plywood supported by a CNC  
processed plywood back board “spine” up to 137 mm  
(5.7 in.) thick, clad with 50 mm (2 in.) curved side  
panels created by high-frequency heating. The bass  
reflex port was modeled after the design concept of the  
TAD compression driver and horn, resulting in the  
reduction of wind noise for clear, deep bass. In order  
to fully realize the drive unit's potential, the drivers are  
securely mounted to the enclosure and the enclosure is  
slanted at a four-degree tilt back, optimizing the unit's  
center of balance. The 150 kg (330 lb) mass of this  
system produces a correspondingly powerful bass  
sound that is both clean and subtle. The teardrop-  
shape both reduces sound diffraction, allowing for  
excellent acoustics, and also serves to eliminate  
unnecessary resonance and internal standing waves.  
The enclosure features rare, elegant natural wood that  
is treated with a transparent finish. Its surface has a  
beautifully polished mirrored finish, the result of the  
meticulous, painstaking work of skilled craftsmen.  
This product is designed to elicit the full potential  
of the natural wood used in its enclosure. Note  
that the color and pattern of the wood is slightly  
different for each unit.

INSTALLATION AND PLACEMENT  
Caution: About installation  
This unit is sold with the understanding that it is to be installed by a properly trained and equipped specialist.  
All matters concerning installation and mounting should be handled by specialists or by your local dealer.  
Pioneer waives all responsibility for damages to this unit as the result of improper installation/mounting,  
improper use, remodeling/alteration, and natural disasters.  
Caution: About the placement of this unit  
This product weighs 150 kg (330 lb). Make sure that you place this product upon a surface that can easily  
sustain this weight. Additionally, note that when using spikes, each spike supports some 50 kg (110 lb), and as  
such may cause damage to flooring underneath a carpet or other surfaces. To avoid causing such damage, be  
sure to place a sufficiently large and strong cushion underneath each spike.  
As a precautionary measure, be sure to not place the unit anywhere where it might fall on a sleeping individual  
in the event of an earthquake.  
Concerning The Placement Of This Unit  
There is an aluminum plate attached to the bottom of the unit's cabinet. It can be placed normally upon a flat  
surface. This unit comes with two types of spikes that you can use to adjust the unit to the shape of the floor for  
best possible placement.  
We recommend the following placement methods:  
For flat surfaces: no spikes  
Thick carpet or mat: cone-shaped spikes  
Thin carpet or mat: round spikes

Installing The Spikes  
Removing The Grille Covers  
WARNING!  
The bass drivers come equipped with grille covers that  
should be removed when the loudspeaker are in use  
(see Figure 6). To remove them, grasp each grille along  
the edges, pull it out, and store it in a safe place in case  
of future use when moving or storing this unit.  
Be sure to use two people when installing  
the spikes. Be careful to not pinch your  
fingers under the loudspeaker and make  
sure the loudspeaker does not fall on its  
side.  
The installation of spikes on the bottom of the unit  
allows you to establish a firm connection between the  
ground and the loudspeaker when placing the  
loudspeaker on uneven surfaces. The bottom of the  
cabinet features three areas for these spikes.  
The use of three spikes for support eliminates the need  
for fine adjustments, allowing you to keep the  
loudspeaker firmly in place. See Choosing Where To  
Place The Loudspeakers on page 10 for help deciding  
where to place the loudspeaker, and Figure 5 for how  
to install the spikes.  
There are screw holes on the aluminum plates located  
on the bottom of the cabinets.

Choosing Where To Place The Loudspeakers  
Loudspeaker placement within the listening room will have a great impact upon the total performance of TAD  
Reference One loudspeakers 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 loudspeakers 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 7. Your listening position should  
be roughly equal to the distance between the two loudspeakers. Also, turn the loudspeakers inward so each axis  
points toward the listening position.  
Next, connect the audio system as described in CONNECTING THE LOUDSPEAKERS on the next page. Then,  
optimize the loudspeaker placement as described in OPTIMIZING THE SYSTEM on page 16.  
WARNING!  
Keeping the spikes inserted can cause damage to the bottom of the unit in the event that you move  
the loudspeaker. Be sure to remove the spikes before moving the loudspeaker to another location.  
In order to protect the bottom of the unit from damage when moving the loudspeaker, you should  
place a thick cloth or mat beneath the system before moving it to a new location.

CONNECTING THE LOUDSPEAKERS  
Single-Wire Connections  
For single-wire connections, connect the high- and low-frequency sections of the crossover network with the  
shorting link that was included with this unit, then connect the (+) wire from your amplifier to either red binding  
post and the (-) wire from your amplifier to either black binding post, as shown in Figure 8.

Bi-Wire Connections  
In a bi-wiring connection, you independently plug in the loudspeakers running from the amp to their respective  
high- and low-frequency plugs. This results in the CST driver and bass drivers being independently connected  
directly to the amplifier, offering you the freedom to optimize the cable type for each of the drivers. Connect one  
set of wires to the bottom set of binding posts (bass driver-specific network). Then connect a second set of wires to  
the top binding posts (CST-specific network). Next, connect both sets of wires to the appropriate terminals on your  
amplifier. Take care to connect both (+) wires to the (+) amplifier terminals and both (–) wires to the (–) amplifier  
terminals, as shown in Figure 9.

Bi-Amplification Connections  
Bi-Amplification allows the best performance from the TAD Reference One loudspeaker by using dedicated  
amplifiers for low- and high-frequency sections. There are two possible configurations, commonly referred to as  
horizontal and vertical bi-amping.  
WARNING:  
Remove the shorting links before connecting speaker cables in bi-wiring 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 loudspeaker. One channel of each amplifier  
drives the low frequency section and the other channel drives the high frequency section, as shown in Figure 10.  
Connect one set of wires and amplifier channel to the bottom set of binding posts (bass driver-specific network).  
Then connect a second set of wires and the other amplifier channel to the top binding posts (CST-specific network).  
Take care to connect both (+) wires to the (+) amplifier terminals and both (–) wires to the (–) amplifier terminals.

Horizontal Bi-Amping  
With this configuration, you may use different stereo amplifiers for the low- and high-frequency sections of the  
loudspeaker (e.g., tube amplifiers for high frequency and solid state for low frequency). Each channel of one  
amplifier drives the low-frequency section of each loudspeaker and each channel of the other amplifier drives the  
high-frequency section, as shown in Figure 11.  
This method requires that both amplifiers have the same gain; otherwise an imbalance will be heard between the  
low- and high-frequency reproduction from the loudspeaker. If in doubt, please consult your TAD dealer.

OPTIMIZING THE SYSTEM  
performance of the CST driver, the strength of the  
side-wall reflections will be reduced, and at the same  
time, the image will be stabilized and focused.  
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 Reference  
One loudspeakers until you get the most even  
progression of the notes.  
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.  
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.  
Final Optimization  
You may find that as you move the loudspeakers 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 loudspeaker and listening positions, whereas  
Also listen to drum sounds. The kick drum should  
sound tight and fast, without low-frequency boom.  
Changes in loudspeaker position of as little as a few  
inches can have a large effect upon bass performance,  
so take time and try many positions.  
imaging is mostly determined by the loudspeaker  
position. Therefore, you may find that if optimizing  
for imaging compromises bass, then changing the  
listening position will bring back bass performance.  
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 loudspeaker in that  
location.  
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 loudspeakers to adequate sound levels. The  
optimum is somewhere in-between. 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.  
Improving Imaging  
Now select music with a strong center image. Listen  
for that image to be exactly centered between the  
loudspeakers, and to be well-focused. If the image is  
unclear and spreads wide, the side walls are probably  
creating strong reflections. Try moving the  
loudspeakers closer together to reduce this effect. If  
this brings them too close, try instead toeing in the  
loudspeakers so that the axis crosses in front of the  
listening position. Because of the superior off-axis

LOUDSPEAKER CARE  
Each TAD Reference One loudspeaker has a polymer finish that requires care similar to a grand piano. For  
accumulated dust and fingerprints, simply wipe the cabinet with the included cleaning cloth.  
CAUTION: Do not use any cleaners or polishes on the cabinet or grille!  
In areas of high humidity, use a dehumidifier, and in areas of excessive dryness, use a humidifier to adjust the room’s  
humidity level. Avoid exposure to direct sunlight, and do not install in areas near by heating appliances.  
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  
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.  
Do not try to force a low-powered amplifier to produce loud volumes of sound (the amplifier’s harmonic distortion  
will be increased, and you may damage the speaker).

DEAR CUSTOMER  
Selecting fine audio equipment such as the unit you’ve just purchased is only the start of your musical enjoyment.  
Now it’s time to consider how you can maximize the fun and excitement your equipment offers. This  
manufacturer and the Electronic Industries Association’s Consumer Electronics Group want you to get the most  
out of your equipment by playing it at a safe level. one that lets the sound come through loud and clear 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.  
To establish a safe level:  
· Start your volume control at a low setting.  
· Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.  
Once you have found a comfortable sound level:  
· Set the volume control and leave it there.  
We Want You Listening For A Lifetime...  
Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for  
a lifetime.  
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from  
loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association’s
