Definitive Technology In-Ceiling Speakers, Model UIW63A


Definitive Technology's Ultimate
Performance Architectural Speakers

Definitive Technology's total commitment to uncompromised sonic superiority has made us the leader in high performance 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 extraordinary 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.

This 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 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
  • Beautiful Decorator-Approved Designer Styling
  • Mounting Templates and Paint Masks Included
  • Optional New Construction Rough-In Kits Available
  • Easy-to-Paint and Moisture-Resistant
  • 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 architectural need (and your decorator's too). These critically acclaimed loudspeakers 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 speakers including high-definition cast-basket bass/midrange drivers and pure aluminum dome tweeters. One listen and you will know they are the finest sounding 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 measurable 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 impactful bass perfectly blend into an ultra-coherent wide-dispersion soundfield which will fill your home with sonic perfection.

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 significant performance advantages in the areas of bass reproduction, lifelike midrange clarity and dynamic range. These sophisticated drivers are engineering 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 features assures high-definition, superb transient response, high-efficiency, high- power handling and extended linear response. In addition, the aerodynamically 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 loudspeaker. 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 addition, the unique silk surround provides better dampening and wave termination. The audible benefits of all this highly advanced engineering include velvety 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 UIW 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 produced 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.

UIW 63/A High-Definition
6.5" Two-Way System

The UIW 63/A is a surprisingly affordable, yet superb sounding round loudspeaker. It combines a stamped-basket version of Definitive's signature 6 1/2" bass/midrange driver with a 1" pure aluminum dome tweeter.

    Comments about Definitive Technology In-Ceiling Pair Speakers:

    I bought a pair of the 63's for my patio. I went with the 63's to save a few bucks over the Definitive Technology's 64's (which I use in my surround sound set-up for surround L and R). They definately dont sound as great as the 64's, but if you are looking for a good speaker for a basic system or for outdoor applications like me, they are well worth it. They sound better than most in-ceiling speakers you will find at Best Buy or another retailer.

    Only thing I dislike about DT's in-ceiling speakers is the installation clips. They are kind of a pain to figure out, however, once you get the knack they aren't too bad. The key is to turn the screws a little more counter-clockwise than the instructions say (about 1 full turn instead of the 1/2 turn the instructions state). Then turn the screws clockwise to seat the mounting clips. THe first set of DT's I bought, I did not do this quite correctly and had to go into my attic to seat the mounting clips. NOT FUN.
