Definitive Technology UIW RCS II Reference In-Ceiling Loudspeaker – White

Clearly Above…and Beyond

The UIW RCS II in-ceiling speaker produces phenomenally rich and immersive sound while it disappears above, virtually hidden in your ceiling. It’s technology that took decades to perfect, but will only take you milliseconds to appreciate.

Invisible Sound, Uncompromised: Reference Audio from Above

UIW RCS II speakers feature precisely-aimed drivers in our patented Wave Launch configuration – including two cast-basket midrange/woofers and a pure aluminum tweeter – angled downward toward the listening area for a full audio experience.

Reference-quality Drivers & Radiators, Flagship Loudspeaker Performance

Ultimate In-Wall series speakers are designed with the same driver technologies as our flagship floor-standing speakers, enabling freestanding speaker-level performance from within your ceiling and walls.

1″ Aluminum Dome Tweeter

The RCSII aluminum dome tweeter delivers a clear, precise high frequency response. Their ultralight, rigid construction enables them to play significantly higher frequencies than we can hear, providing effortless, distortion-free highs within and beyond the audible range.

Wave Launch™ Technology for a Theater-Like Presentation

The RCSII’s Patented Wave Launch™ technology turns overhead speakers into engineering wonders, using precisely configured dual-angle baffles to create acoustics that make you believe you’re in front row center.

Installation Flexibility for Reference-Level Rooms

Whether new or existing construction, walls or ceilings, residential or commercial, the UIW RCS II features simple, secure installations. From metal pivoting lock arms to paintable grilles and frames to fully sealed enclosures, Definitive Technology engineers designed speakers that put installation simplicity on equal footing with sound quality.

Fully Enclosed for Powerful Sound where You want It

The UIW RCS II is fully enclosed and sealed with dense, acoustically inert, anti-resonant, anti-vibration Medite® wood. With the RCSII, you’ll hear loud, accurate, uncolored midrange and tight, powerful bass with no buzzing or sound leakage into walls and ceilings.
