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 Launchâ„¢ 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.

For Reference-Level Rooms
Whether new or existing construction, walls or ceilings, residential or commercial, UIW Reference Series loudspeakers feature 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
UIW Reference Series loudspeakers are 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.
