The R10 Series in-ceiling speakers offer homeowners the refined, musical quality of Triad speakers for their whole home. These speakers are built around reinforced poly-mica woofers for superior bass and aimable, Teteron dome tweeters to deliver a full, natural sound.

The four models are voice matched?allowing homeowners to mix and match speakers to meet the needs of each room while providing identical tonal qualities throughout the home.

The R18DT version incorporates dual tweeters into a single speaker enclosure, perfect for delivering stereo sound into smaller rooms.

R10 speakers ship with white, round, microframe grills that are low profile and look great. They utilize embedded magnets for fast installation and a snug fit. Custom paint-matched round or square grills are available separately and painted at the factory for a perfect finish that blends seamlessly with any interior design.
