The UIW RCS III 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.

UIW RCS III 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.

1″ Aluminum Dome Tweeter

The RCSIII 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.

Dynamic Midrange/Woofer

Most in-wall speakers lack the larger driver area of floorstanding speakers. The RCSIII’s 4.5” midrange/woofer drivers match butyl rubber surrounds with rigid polypropylene cones in cast baskets to provide a much greater cone excursion than other comparably-sized drivers. The result is superior midrange and bass performance, wrapped in a compact, stealthy package.

Passive Bass Radiators

Each RCSIII includes twin 5.25” passive bass radiators. Passive radiators create more bass than comparably sized sealed or ported designs. The extra surface area moves more air, resulting in bigger and deeper low end that works beautifully on its own or mates seamlessly with subwoofers at a variety of crossover points.

Wave Launch™ Technology
for a theater-like presentation

The RCSIII’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.

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 RCSIII, you’ll hear loud, accurate, uncolored midrange and tight, powerful bass with no buzzing or sound leakage into walls and ceilings.
