Definitive Technology DI 8R

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.

Meticulously engineered with a low-profile design, the DI 8R is nearly invisible in your ceilings or walls. Better yet, it casts sound over a wide area, delivering immersive, lifelike audio from any angle.

  • Powerful Performance
  • Clear, Clean, and Detailed
  • Tailored to Your Space


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™ Technology 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.


Advanced Technologies for the details that make all the the difference

The DI 8R 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 tweeter with the woofer provides broader sound dispersion and more natural balance.


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.


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. 


New Construction Brackets for installation made easy

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.
