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 Axially-Aligned configuration of the tweeters with the woofer provides broader sound dispersion and more natural balance.
Whether new or existing construction, walls or ceilings, residential or commercial, DI Series speakers offer simple, stealthy installations. Our engineers have extensive custom installation experience, and have felt your pain when working with hastily-engineered products. From pivoting lock arms to paintable grilles and frames to sure-grip magnetic grille fasteners, DI Series speakers are installer-friendly to the extreme.
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.
Whatever the setting—residential or commercial, music room or home theater—DI Series has designed a disappearing act ready to entertain you. From round or square ceiling speakers, to in-wall speakers, to Bipolar surround speakers, to in-wall subwoofers, DI Series is ready to rock a venue of any size—invisibly. Mix and match as you please, confident that you’ll always enjoy Definitive Technology's legendary speaker voicing.
