UIW RCSIII Reference In-Ceiling Speaker
In-ceiling front main, center, or surround speakers for built-in home theater installations. They feature two 4-1/2" cast basket active drivers and a Pure Aluminum tweeter on an angled baffle aimed at the listening area. Proprietary Wave Length (patent pending) baffle geometry and acoustic treatment materials serve to create the illusion that the speakers are directly in front of the listener rather than up in the ceiling. The active drivers are pressure-coupled to two 5-1/4" race-track Low-Bass Radiators for exceptional bass and perfect blending with free-standing or built-in subwoofers.

The future has arrived! Mythos XTR-50
The Definitive Mythos XTR-50 is the first high performance on-wall speaker whose depth matches that of today’s ultra-thin TVs. It is a mere 1.5 inches deep when mounted on a wall, shallower than many ultra-thin TVs when they are wall-mounted with their factory sanctioned mounting hardware. Beyond its utility and clean modern styling the XTR-50 stands out due to its uncompromising sound quality equivalent to full-size speakers. Science fiction films have long featured impossibly thin video screens mounted on walls or floating in air. While the floating-in-air technology might be some time off, super shallow video screens are here now. TVs less than 2 inches thick are in stores now and more are on their way. Compared to these super slims, today’s “made for plasma” speakers are too deep and look out of place. If you have an ultra-thin TV you’re going to want to use ultra shallow speakers.

DI-5.5BPS
The Ideal Surround Speaker.

With a pivoting 1" Pure Aluminum dome tweeter featuring a specially shaped housing that avoids the diffraction distortions of traditional post-mounted tweeters, and a sophisticated adjustable crossover network, the Disappearing In-Wall models deliver the kind of lifelike sonic performance and broad even dispersion that have made Definitive Technology the most highly reviewed speaker brand in the USA.Extraordinary High-Performance Speakers that Virtually Disappear in Your Room!
They take up no floor space and virtually disappear from view. We specifically designed the DI 5.5BPS for surround channel duties. You can install them in walls or ceilings for enveloping surround effects with smooth natural response and precise detail retrieval.
Definitive's Disappearing In-Wall Speakers Just May be the "Holy Grail" of Built-in Speakers
You want great sound everywhere in your home, but you may not always have room for or want the visual intrusion of free-standing speakers. Built-in flushmount speakers seem to be the answer but in practice they don't exactly disappear in the room, in fact many "in-wall" speakers call attention to themselves and create friction between your decorator and your audiophile sensibilities. Worse yet, most built-in speakers fall short on the performance end as well. Would Definitive allow you to suffer with bad sound? Oh no, no, no!
Definitive’s Disappearing™ In-Wall series speakers feature near-invisibility thanks to their small area, hidden flange design, and low profile micro-perf grilles. They are as easy to install as traditional flanged flush-mount speakers, and don’t require custom sheetrock/spackle skills to install yet they are practically invisible.
Great Sound for Everyone in the Room
DI Series speakers disperse sound over a very wide area so that the sound is well-balance and natural regardless of where you are relative to the speakers.

Now you can enjoy the incomparable sound of Definitive Technology anywhere around your home with the groundbreaking AW-5500 and AW-6500 All-Weather loudspeakers.
These technology-packed wonders feature high excursion active drivers pressure-coupled to racetrack-shaped Low-Bass Radiators to give you more than double the bass output while maintaining a weather-tight seal for ultimate placement flexibility, reliability, and performance.
With their fully sealed design, aluminum grilles, and rugged PolyStone enclosures, the AWs can be fully exposed to the elements and still reliably deliver their indoor speaker sound quality for years of outdoor listening enjoyment. Their integrated galvanized steel brackets and unique shape allow a full 360 degrees of rotation allowing the listener to orient the active drivers toward the listening area. Pointing the active driver baffle towards the listener while the Low-Bass Radiator side faces the wall or ground gives you the ideal balance of clear mids, extended highs, and thunderous bass even in the tough acoustic conditions of the outdoors.
Both models are available in Black and White. Want a custom color? You may paint the white version any color you wish after masking the baffles.
The AW5500 features a 5-1/4" active driver pressure-coupled to a 5" x 8" Low-Bass Radiator for a total bass radiating area greater than that of an 8" conventional woofer, while the AW6500's 61/2" driver and 5-1/2" x 10" Low-Bass Radiator exceeds the radiating area of a 10" woofer - imagine all that bass from speakers small enough to unobtrusively place anywhere. Both AW models use Definitive's trademark Pure Aluminum dome tweeter for unexcelled high frequency extension and detail. Now you can have it all - the great sound of Definitive indoor speakers on the patio, deck, garden, or in the sauna.
