The Definitive Technology DI 6.5STR is a discreet yet powerful in-ceiling speaker that delivers immersive stereo sound from a single unit. Designed for spaces where installing two separate speakers isn’t practical-such as hallways, kitchens, bathrooms, or offices—this speaker features a 6.5″ BDSS™ midrange/woofer with dual voice coils and two pivoting 3/4″ aluminum dome tweeters for broad stereo dispersion.
With a frequency response of 26 Hz – 30,000 Hz, the DI 6.5STR offers deep bass, clear mids, and precise highs, ensuring a rich and dynamic listening experience. The speaker is rated to handle up to 125 watts per channel, with a sensitivity of 90 dB for efficient power use.
Installation is effortless, thanks to its low-profile, paintable grille and hidden flange design, allowing it to blend into any décor. The magnetic grille makes adjustments simple, and the spring-loaded speaker terminals provide a secure connection.
Ideal for whole-home audio systems, this speaker lets you enjoy room-filling stereo sound without visible hardware, making it a perfect choice for modern, minimalist spaces.
