“Truly outstanding!”
—Home Theater Magazine
D
efinitive Technology’s total commitment to uncompromised sonic superiority has made us the leader in high perfor-
mance loudspeakers. We are pleased to introduce our architectural loudspeakers. This extensive line of reference-
quality loudspeakers offers the highest level of sonic performance and construction quality. They are designed for
easy in-wall/in-ceiling installation in homes as well as commercial spaces. Sound quality, of course, is extraordi-
nary and the speakers have been voiced for warm, rich sonic reproduction by Definitive engineers to the same
state-of-the-art, high-end standards as all Definitive loudspeakers.
These Remarkable Systems Feature:
• Absolute State-of-the-Art Sonic Performance for Music
and Home Theater Perfection
• Low Diffraction Driver/Baffle Interface
• Easy-to-Install Metal Pivoting Dog Mounting System
• Ultra-Wide Dispersion for a Huge, Rich, Lifelike
Soundfield Throughout Your Room
• Pure Aluminum Dome Tweeters w/Silk Surrounds
• Rigid Non-Resonant Glass-Filled Low Profile Frames
• Cast-Basket Bass/Midrange Drivers (except 63/A& 83/A)
• Beautiful Decorator-Approved Designer Styling

• Five-Year Parts and Labor Warranty (UIWs)
We offer a wide range of ultimate performance round, rectangular, bipolar,
dual-channel and outdoor speakers which are perfect to suit your every archi-
tectural need (and your decorator’s too). These critically acclaimed loudspeak-
ers have been painstakingly engineered to ensure that they achieve the same
level of superior sonic performance as our flagship floor-standing speakers,
which are renowned for offering the finest sound quality possible. In addition,
their subtle and understated, but beautifully sculpted, upgraded styling will
complement any decor. Our architectural speakers utilize the same state-of-
the-art components and technologies developed for our top-of-the-line speak-
ers including high-definition cast-basket bass/midrange drivers and pure alu-
minum dome tweeters. One listen and you will know they are the finest sound-
ing architectural in-wall/in-ceiling and outdoor speakers in the world.
The Sonic Superiority of Definitive’s Architectural Speakers
The most striking difference you will hear when you listen to Definitive
speakers is the extremely big, open quality to the sound. Smooth natural sound
is produced with a lifelike, three-dimensional character that really brings
music and movies to life. It is as if the music or cinematic action is actually
being performed live in your home. Of course their performance by all mea-
surable parameters is superb, but it is their almost magical ability to suspend
disbelief and recreate the illusion of a live performance which really sets our
architectural speakers apart. And so does the way their velvety smooth high-
definition midrange, crystal clear high frequencies, and deep, tight and impact-
ful bass perfectly blend into an ultra-coherent wide-dispersion soundfield
which will fill your home with sonic perfection.
Our High-Definition Cast-Basket Bass/Midrange Drivers
All our architectural speakers (except the UIW 63/A and UIW 83/A) utilize
Definitive-developed high-definition cast-basket bass/midrange drivers for sig-
nificant performance advantages in the areas of bass reproduction, lifelike
midrange clarity and dynamic range. These sophisticated drivers are engineer-
ing marvels which incorporate deeply drawn mineral-filled homopolymer
cones, combined with butyl rubber dustcaps and surrounds, high-temperature
vented voice coils and massive magnet structures. This combination of fea-
tures assures high-definition, superb transient response, high-efficiency, high-
power handling and extended linear response. In addition, the aerodynamical-
ly designed, magnetically inert, non-resonant cast baskets minimize reflections
of the sound radiating from the back of the cones and preserve structural and
magnetic integrity.
Definitive’s Moving-Coil Pure Aluminum Dome Tweeters
The accuracy of high frequency reproduction really sets apart a great loud-
speaker. The Definitive-developed magnetic fluid-cooled moving-coil pure
aluminum dome tweeters are of a unique design that synergistically brings
together the performance advantages of metal domes (greater clarity) and soft
domes (smoother sound and better dampening) in one state-of-the-art tweeter
design. The pure aluminum dome is specially annealed (to “relax” the crystal
structure) and acoustically loaded by a precisely configured acoustic phase
plug/lens (to assure perfectly controlled, absolutely linear movement). In addi-
tion, the unique silk surround provides better dampening and wave termina-
tion. The audible benefits of all this highly advanced engineering include vel-
vety smooth extended high frequency response (beyond 30 kHz), greatly
reduced distortion, improved transient response, notably higher definition and
crystal clear lifelike clarity.
Non-Resonant Low-Diffraction Baffles Maintain Sonic Purity
A speaker’s baffle, as well as the driver/baffle interface, plays a large part
in its sonic performance. Diffraction, or the secondary radiation of sound
caused by driver and baffle edges and other protrusions and surface anomalies
can color the sound and impart a boxy coloration.
The UIWs and AW Series speakers are carefully engineered to minimize
diffraction problems. In addition, the resonant vibration of a speaker baffle can
also impart coloration. We engineer the baffles for maximum stiffness and
mold them from a special glass-filled polymer compound in order to eliminate
baffle resonance which would otherwise interfere with the pure sound pro-
duced by Definitive’s high-definition drivers. Finally, a special wall clamping
system was designed which uses special high-tension clamps (and more of
them) in order to further stiffen the baffle and eliminate unwanted resonance.
The Sonic Benefits of our Extraordinary Bipolar UIW Speakers
Definitive Technology is famous for our high-end, floor-standing bipolar speak
ers. They have two complete sets of drivers which face in different directions and
radiate sound in an omnidirectional pattern, the way sound is radiated in real life.
We make two bipolar in-wall/in-ceiling loudspeakers, the UIW BP/A and UIW
BPZ/A, which provide you with a lifelike balance of early-arrival information
(giving focus, clarity and location data) and properly delayed-arrival information
(enhancing spaciousness and conveying the lush three-dimensional soundstage of a
live music or cinematic performance). The bipolars literally immerse you in a
soundfield which is rich, warm, ultra-clear and vibrantly alive. In addition, the
wide-dispersion characteristics of our bipolar speakers assure a superb panorama
of lifelike sound for every listener in your room, wherever they sit or stand.
The UIW bipolars are perfect for use anywhere you want a high-performance,
flush-mount architectural speaker, and they are clearly the in-wall or in-ceiling
speakers of choice for side surrounds, rear surrounds or center rear surrounds for
Dolby Digital*, Dolby Surround* or any home theater surround sound system.
Choose Our Ultimate Performance Architectural Speakers
for a Spectacular Built-in Home Theater System
In addition to bringing music into every room in your house, Definitive UIW
speakers are perfect for a spectacular-sounding, high-performance home theater
system. Choosing the perfect system is easy because all Definitive speakers are
engineered to have the same timbral balance and sonic signature; so they can all be
used together in any combination with excellent results. The top-of-the-line signa-
ture Definitive UIW home theater system would use three matching UIW BPZ/As
or UIW 75s across the front and UIW BPZ/As as rear and/or side surround speak-
ers. This system will sound great and deliver excellent bass without a separate sub-
woofer. However, you can add any of Definitive’s superb powered subwoofers for
even higher performance. Remember: any combination of UIWs will work well
together and deliver superior performance; so pick the ones that best suit your bud-
get as well as your specific size, design, mounting and listening requirements.
Save Space with Our Unique Two-Channel DCS Speakers
With two complete channels in one (angled for proper separation) our UIW
DCS speakers are the perfect space-saving solution for providing high quality
stereo from a single in-wall/in-ceiling speaker anywhere in your home that you
want beautiful music. The DCSs are also perfect as a single speaker two-channel
rear surround for Dolby Digital, Prologic* and EX* or as a single rear plus side
surround for Dolby EX (two DCSs will reproduce all four surround channels).
UIW Warranty: 5 years parts & labor. AW100 Warranty: 3 years parts & labor.
