Triad Speaker In-Ceiling R20 Series OpenRound

Triad Speaker In-Ceiling R20 Series OpenRound

Triad’s R20 series in-ceiling speakers are engineered for music enthusiasts that are looking for exceptional sound in every room. The series utilizes carbon fiber woofers for superior bass response and durability. A one inch silk dome tweeter offers smooth, high-frequency sound and is aimable to offer greater installation flexibility.

The R20 series is voice-matched, allowing homeowners to choose the right size speaker for each room while delivering identical tonal qualities throughout the home.

The R28DT incorporates dual tweeters into a single speaker enclosure, making it the perfect choice for delivering stereo sound into smaller rooms.

R20 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.
