About Definitive Technology UIW RSS III

What sets the UIW RSS III 3-Way In-Ceiling/In-Wall Reference Bipolar Speaker apart is its masterful blend of discreet design and exceptional acoustic performance. Engineered for the discerning audiophile, this speaker is an ideal choice for custom home theaters that demand the highest quality of surround sound without compromising on aesthetics.

Naturalistic Surround Sound Experience:
The UIW RSS III's bipolar arrays are meticulously crafted to evenly disperse sound across a wide listening area, creating a naturalistic surround sound environment. This design ensures that every spot in the room becomes the 'sweet spot,' providing an enveloping audio experience akin to that of a live performance.

Pristine Highs with Dual Pure Aluminum Dome Tweeters:
Equipped with dual 1" pure aluminum dome tweeters, the UIW RSS III delivers pristine, crystal-clear high frequencies. The lightweight yet rigid construction of these tweeters facilitates an extended high-frequency response, producing effortless and distortion-free highs that soar beyond the limits of human hearing.

Dynamic Midrange and Powerful Bass:
The speaker boasts a pair of 3.5" cast-basket midrange/woofer drivers, designed to deliver dynamic and robust sound. These drivers are complemented by butyl rubber surrounds and rigid polypropylene cones, allowing for greater cone excursion and superior midrange and midbass performance. The compact design does not sacrifice power or clarity, ensuring a full-bodied audio experience.

Enhanced Bass with Passive Radiators:
Each UIW RSS III speaker includes two 3.5" pressure-coupled Low Bass Radiators, which generate deeper and more dynamic bass than traditional sealed or ported designs. This innovative approach to bass enhancement allows for a more impactful and cinematic sound, perfect for immersing viewers in their favorite films and music.

Versatile Installation Options:
Designed with both residential and commercial applications in mind, the UIW RSS III offers flexible installation options for new or existing constructions, in walls or ceilings. The speakers feature metal pivoting lock arms, paintable grilles and frames, and fully sealed enclosures, ensuring a straightforward and secure setup while maintaining superior sound quality.

Optimized Sound Directivity:
For ceiling installations, the UIW RSS III's driver arrays can be rotated 90 degrees to optimize sound directivity towards the listening area. This feature allows for tailored audio dispersion, ensuring the best possible surround sound experience regardless of room layout.

Fully Enclosed Design for Uncompromised Audio:
The fully enclosed design of the UIW RSS III, constructed with dense, acoustically inert Medite wood, guarantees that the sound remains pure and powerful where it's intended. This enclosure minimizes unwanted resonance and vibration, preventing sound leakage into adjacent walls and ceilings.

In summary, the UIW RSS III 3-Way In-Ceiling/In-Wall Reference Bipolar Speaker with 2x 3.5" Woofer is a testament to Definitive Technology's commitment to audio excellence. It offers an immersive 360-degree soundstage, theater-like presentation, and flagship driver technologies, all while maintaining a discreet presence in any sophisticated home theater setup.
