Cinematic Performance

With its high-technology flush-mount enclosure that disappears into the environment, the UIW RLS III delivers uncompromising sound that’s heard, but never seen. It provides thrilling sound with room-filling bass, stunning detail, and theater-reference volume levels that rival the best freestanding speakers without the clutter.

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.

The RLSIII 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.

Most in-wall speakers lack the larger driver area of floorstanding speakers. The RLSIII's 5.25" 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.

Each RLSIII 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.

Installation Flexibility

Customize to your home

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