Reference Audio from Above

Reference-quality Drivers & Radiators
Flagship Loudspeaker Performance

Ultimate In-Wall series speakers are designed with the same driver technologies as our flagship floorstanding 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, 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.
