Definitive Technology DI 6.5STR – 6.5″ In-Wall / In-Ceiling Speaker

The 6.5STR is practically invisible, yet perfectly powerful. Feeding both left and right channels into one unit, this stereo loudspeaker delivers the performance of much larger traditional speakers, with a patented BDSS™ midrange/woofer featuring dual voice coils, and dual tweeters for broad stereo dispersion over a wide area. Designed to stay cleverly hidden from view in hallways, kitchens, baths, offices, wherever, it’s the ideal way to enjoy multidimensional sound in a limited space. The culmination of decades of engineering, DI Series Loudspeakers deliver sensational sound quality while virtually disappearing into walls and ceilings with our hidden flange design. Treat yourself to dynamic bass, smooth midrange, and sparkling treble with little impact on your décor. DI 6.5STR speakers feature an innovative dual-angle tweeter configuration that combines with the dual voice coil mid/bass woofers for true stereo sound from a single speaker chassis. Plus, the ultralight, rigid construction of DI Series aluminum dome tweeters enables them to play significantly higher frequencies than we can hear, enabling optimum linearity within the range of human hearing. Adjust the Environmental EQ switch to tailor tweeter output for your listening environment. Engage the [+] setting to boost treble in sound-absorbing rooms, or the [–] setting to reduce treble in lively rooms. Leave in the Center position for rooms with average reflectivity.  Plus with pivotable tweeters you can also fine tune the directivity to maximize the dispersion in your space. For more bass in less space while keeping midrange detailed and responsive, the DI 6.5STR’s 6.5” mid/bass woofer cone leverages our exclusive Balanced Double Surround System (BDSS™) driver technology. The double butyl rubber surrounds produce a much greater cone excursion than other comparably sized drivers. And the DI 6.5STR’s rigid PolyStone™ basket provides a sturdy launching pad for the powerful excursion. With BDSS drivers, you’ll enjoy superior midrange/midbass dynamics and detail in packages sized for stealth. The DI 6.5STR features a sophisticated adjustable crossover network with custom, high-precision components for superior sonic purity. Surrounding the BDSS driver is a specially-contoured AeroRing™ that precisely distributes natural, well-balanced sound by minimizing diffraction. The Axially-Aligned configuration of the tweeters with the woofer provides broader sound dispersion and more natural balance. Hidden flange architecture is fantastic for décor, because the nearly border-free design virtually disappears into walls and ceilings. What isn´t fantastic is the typical installation complexity. However, DI Series hidden flange designs are as easy to install as traditional flanged flush-mount speakers, and don´t require custom Sheetrock or spackle skills to get their practically invisible look. All DI Series speaker grilles and grille frames are paintable, with easy step-by-step instructions. Once you have your perfect look, powerful neodymium magnets attach the grilles to the speakers for a secure, tool-free finish. For new construction projects, streamline your DI Series speaker installations with the optional Pre-Construction Rough-in Brackets. Easily attach the bracket to studs or joists before the drywall goes up, using your choice of nails, drywall screws, or construction staples (not included). Adjustable arms allow for unusual stud or joist locations. Manual Info Sheet
