Definitive Technology DT 6.5STR DT Custom Install Series Round 6.5″ Single Stereo In-Ceiling Speaker

Definitive Technology DT 6.5STR In-Ceiling Stereo / Surround Speaker

The Definitive Technology DT 6.5STR is a flexible in-ceiling loudspeaker designed to perform double duty as both a single-point stereo speaker and a surround channel speaker. With the flip of an integrated switch, it transitions seamlessly from delivering left and right stereo channels from one speaker to providing immersive surround sound for home theater environments. This versatility makes it an ideal solution for smaller spaces such as bathrooms, kitchens, hallways, and bedrooms, as well as for surround applications where wide dispersion and balanced coverage are essential. The speaker features a 6.5-inch polypropylene mid-woofer that produces controlled bass response and articulate midrange output, while dual 0.75-inch annealed aluminum dome tweeters ensure clear, detailed high frequencies. The dual-tweeter configuration enhances stereo separation and broadens sound dispersion across the listening area. Composite-filled driver cones with rubber surrounds improve durability and acoustic transparency over long-term use. A high-definition crossover network using precision components ensures smooth frequency transitions and accurate tonal balance. The low-profile micro-perforated grille attaches magnetically and can be painted to match surrounding décor, allowing the speaker to visually disappear into the ceiling. Engineered for wide off-axis response and enhanced room coverage, the DT 6.5STR delivers rich, full-range sound well beyond its compact size while maintaining a clean, unobtrusive architectural appearance.
