Description

The Sonance Reference R1SUR in-wall surround speaker brings cinema-grade surround performance into a standard 2×4 wall cavity while minimizing visual impact. Designed as part of Sonance’s Reference series, the R1SUR combines fourth-generation coaxial driver technology and separate crossover networks for improved imaging and low distortion. Dual carbon-fiber/Rohacell laminated woofers provide the mid / low energy required for immersive surround channels, while dual ferrofluid-cooled 1″ ceramic dome tweeters reproduce crisp, extended highs. The speaker includes a low-profile, paintable magnetic grille and an integrated enclosure to reduce sound transfer into adjacent rooms — making it ideal for dedicated home theaters or living rooms where both performance and aesthetics matter.
