Definitive Technology UIW RCS II Reference In-Ceiling Speaker (Each)

The Definitive Technology UIW RCS II Reference In-Ceiling Speaker delivers immersive, theater-quality sound while remaining virtually invisible. Designed for high-end home audio systems, this speaker utilizes Wave Launch™ technology, an innovative feature that directs sound down and toward the listener, mimicking the experience of front-facing speakers. Whether used as a left, right, or center channel in a home theater system, the UIW RCS II provides crystal-clear highs, a balanced midrange, and deep, resonant bass.

At its core, the UIW RCS II features a 1-inch aluminum dome tweeter for pristine high-frequency reproduction, dual 5.25-inch polypropylene midrange/bass drivers for rich, detailed audio, and dual 6.5-inch pressure-coupled passive radiators that enhance low-frequency response, adding depth and impact to music and movies.

A key advantage of the UIW RCS II is its built-in, fully sealed back-box, which ensures consistent sound quality regardless of ceiling cavity size. This enclosure not only improves performance but also prevents dust and debris from affecting the speaker’s components.

For seamless integration into any space, the speaker includes a paintable grille, allowing it to blend effortlessly with your ceiling. Its easy installation process, complete with a wall mounting template and pivoting lock arms, ensures a hassle-free setup in new or existing constructions.

Whether you’re designing a custom home theater or a high-fidelity in-ceiling music system, the Definitive Technology UIW RCS II is engineered to deliver exceptional sound that feels like it’s coming from in front of you—not above.
