Environmental EQ
for fine-tuned highs in any space

Adjust the Environmental EQ switch to customize 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.

Exclusive BDSS™

for more bass in less space

For more bass in less space while keeping midrange detailed and responsive, the DI 8R 8″ mid/bass woofer leverages our exclusive Balanced Double Surround System (BDSS™) technology. The double butyl rubber surrounds produce a much greater cone excursion than other comparably sized drivers. And the DI 8R´s rigid PolyStone™ basket provides a sturdy launching pad for the powerful excursion.

With BDSS drivers, you´ll enjoy superior midrange/bass dynamics and detail in packages sized for stealth.

Paintable Magnetic Grille
for the final custom touch

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.

All the Stealth
none of the complexity

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.


Installs Easily
and Reliably

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.
