Definitive Technology DT6.5STR Single Stereo & Surround In-Ceiling Speaker - Each
Definitive Technology DT6.5STR Single Stereo & Surround In-Ceiling Speaker
Definitive Technology's DI 6.5STR stereo speaker is an ideal solution in areas where you don't have room for a pair of speakers, like hallways, bathrooms, or kitchens. This speaker installs flush in your ceiling. With its paintable, low-profile grille and hidden flange, it's practically invisible.
The DI 6.5STR pairs two aimable 3/4" aluminum tweeters with a 6-1/2" driver for precise highs, full-bodied bass, and impressive dynamic range. The speaker features inputs for both left and right channels, so you'll hear both halves of stereo music.

The Definitive Technology Disappearing In-Wall loudspeaker (DI Series) offers high-quality sound from a speaker that is barely visible when installed in a wall or ceiling. The Definitive DI Series incorporates a BDSS driver, pivoting tweeters, and integrated flanges behind an unobtrusive grille to provide audiophile-grade sound quality with an almost invisible appearance. The DI 6.5STR is a mere 8-5/16" (21.04cm) in total visible diameter, which is about the same size as competing 5-1/4" in-wall/in-ceiling models.
Disappearing In-Wall Design: The DI 6.5STR features Definitive Technology's Disappearing In-Wall Design. The mounting flange thickness of the in-wall/in-ceiling loudspeaker is no more than 2.5mm (0.099") and is completely covered by the grille that stands a mere 3.5mm (approx 0.125") from the wall surface. The grille is "micro-perf", that while presenting an opaque appearance, actually has more open area than typical perforated metal grilles allowing the sound to pass through with less interference and better fidelity. Behind the metal grille is an acoustically transparent proprietary cloth scrim that effectively blacks the dark "shadow" of the black speaker parts from showing through the grille.
Stereo Application:The DI 6.5STR is a "stereo" speaker, both left and right channels are fed into a single speaker. Dual angled tweeters disperse the sound in broad area to approximate the spaciousness of two speakers. The DI 6.5STR is the perfect solution in spaces where you want sound, but where using two speakers is not practical or economical-such as hallways, kitchens, bathrooms and offices.
Pivoting Aluminum Dome Tweeter with Waveguide: The DI Series in-wall/in-ceiling loudspeaker uses two Definitive Technology's proprietary ceramic-coated annealed aluminum 0.75" dome tweeters. The DI 6.5R tweeters are post mounted, and the tweeters' housing is specially smoothed and shaped to use it as an extremely effective low-diffraction waveguide. The aluminum dome tweeters features a pivoting design which allows you to focus the sound toward or away from your listening area depending on the application.
BDSS Drivers: The DI 6.5STR uses a 6.5" BDSS driver for wide-bandwidth accurate frequency response, broad dispersion, low distortion, and maximum detail retrieval. The 6.5" BDSS driver cone is supported by specially tuned soft rubber surrounds at both the outer and inner edges. The double surrounds allow the cone to have longer excursion without distortion. As bass output is a function of both a cone's diameter and excursion, the higher excursion BDSS system brings the benefit of higher bass output from smaller drivers. The DI 6.5STR's 6.5" BDSS driver has the bass output and dynamic range of a typical 8" driver.
Linkwitz-Riley Crossover Network: The Definitive Technology DI 6.5STR's second order (12dB/octave) Linkwitz-Riley crossover offers a smooth frequency and phase transition from driver to tweeter for natural midrange response and excellent off-axis performance. A Zobel network flattens the impedance curve of the speaker making it easier for today's digital amplifiers to drive the speakers. Custom tight-tolerance (+/- 5%) components are used throughout the crossover for superb unit-to-unit performance consistency. Superior metal film capacitors are used in the high-pass section and the Zobel network for extended high frequency response. Oversize inductors (coils) avoid saturation thereby maintaining the wide dynamic range capabilities of the driver.
Environmental EQ: The Environmental EQ switch (on top-frame of speaker) provides a 1dB broad bandwidth tweeter output lift or cut to compensate for highly absorptive or reflective acoustic environments.
AeroRing: The dimpled AeroRing is soft Sanoprene rubber and serves several important functions. First, it damps the basket/flange assembly nearest its thinnest part (the flange) to prevent resonance. Second it prevents the grille from rattling in the unlikely event that it makes contact with the speaker frame. It also provides a smooth transition for the waveform coming off the cone. Similar to the dimples on a golf ball that reduce turbulence to aid in longer flight, the dimples on the AeroRing promote smooth "laminar" air flow over the surface thereby reducing diffraction effects. The DI Series in-wall/in-ceiling loudspeakers sound clear, natural, and disperse their sound over a wide area.
PolyStone Basket: The driver basket, mounting flange, and mounting system of the DI 6.5STR is one piece of cast PolyStone; Definitive's exclusive formulation of polymers and minerals that combine the rigidity and strength of metal with the resonance damping properties of plastics. As a result of the one-piece mounting system, the DI 6.5STR offers increased strength, a compact size, and maximized cone area. Besides being more space efficient than multi-piece construction, it also contributes to the superior sound quality of the DI Series speakers.
Connections: The DI 6.5STR features a two pairs of heavy-duty, gold-plated, spring-loaded wire terminals that have oversized holes to accept up to 10 gauge wire.
Definitive's GaussGrip System: Definitive's GaussGrip system securely holds the grille of the in-wall/in-ceiling loudspeaker in place with powerful magnets. Simply lay the grille over the speaker and its secure. Taking off the grille is just as easy and fast; no special tools that can chip the grille paint are required. All you need to remove the grille is your fingers.
Paintable Grille The DI Series in-wall/in-ceiling loudspeaker's white "micro-perf" cloth grille can be spray painted to match the color of your wall or ceiling without any loss of sound quality. Simply remove the grille from the speaker and place it on a drop cloth, newspaper, or plastic sheet and spray paint it with canned spray paint that closely matches the desired finish/color; or with indoor latex paint using an airbrush or spray gun (available at home improvement stores). The paint must be diluted to a 6:1 ratio of latex paint to water. Do not remove the backing cloth (scrim). Apply the paint in a series of thin coats sprayed at 45-60 degrees from the grille surface, allowing each coat to fully cure before applying additional coats. To ensure that the paint distribution is evenly applied, each coat should be applied from 4 different directions (N,S,E, & W) to ensure an even coverage on the grille.
