Triad’s R20 Series in-ceiling speakers are engineered for
music enthusiasts who 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 oers smooth, high-frequency sound and
is aimable to oer greater installation flexibility.
The R20 Series is voice matched—allowing homeowners
to choose the right size of 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 paintmatched round or square grills are available separately
and painted at the factory for a perfect finish that blends
seamlessly with any interior design.
