Product Description
The Definitive Technology DI 6.5STR is a specialized in-ceiling speaker engineered to provide a complete stereo soundstage from a single mounting location. This "Single-Point Stereo" model is equipped with a dual-voice coil 6.5-inch midrange/woofer and two independent 0.75-inch aluminum dome tweeters. By reproducing both the left and right audio channels, it eliminates the "hollow" sound often found in small areas when only one half of a stereo pair is present, making it an essential solution for kitchens, walk-in closets, and corridors.
As part of the Disappearing In-Wall series, the DI 6.5STR focuses on a minimalist aesthetic. It utilizes a flangeless design and a micro-perforated magnetic grille that sits almost flush with the ceiling, allowing it to hide in plain sight without sacrificing audio quality. The woofer features Definitive Technology's patented BDSS (Balanced Double Surround System) technology, which provides the excursion and power of a much larger driver, resulting in a remarkably wide frequency response that reaches as low as 26 Hz.
Installation is designed for simplicity and precision. The speaker features high-quality spring clip connectors for secure wiring and a standard round cutout. Because it lacks a bulky back box, it fits easily into standard ceiling cavities with a mounting depth of 3.5625 inches. For listeners who demand premium, full-range high-fidelity sound in spaces where a traditional two-speaker setup is impractical, the DI 6.5STR offers the perfect balance of performance and invisibility.

Does this speaker require two sets of speaker wires?
Yes. To get the single-point stereo effect, you must run both a Left and Right speaker wire from your amplifier to the single DI 6.5STR unit.
Can this be used as a standard mono speaker?
While it is designed for stereo, you can bridge the inputs or use it in mono; however, for standard mono applications, the traditional DI 6.5R model is usually recommended.
Is this speaker moisture-resistant for use in a shower?
While it is frequently used in bathrooms due to its space-saving design, it is not rated for "Full Exposure" or high-moisture environments. It should be placed away from direct steam or water spray.
