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.
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.
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.
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.
