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.

Stereo Imaging from a single speaker

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.

Environmental EQ fine-tuned the highs for any space

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.

Exclusive BDSS™ Technology midrange/bass woofer

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’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.

Acoustic Wizardry for the details that make the difference

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.
