Definitive Technology DT 8R Custom Install Series Round 8″ In-Ceiling Speaker – White

Superior In-Ceiling Sound

The DT 8R is a bang-for-your-buck in-ceiling superstar for multi-room and home theater applications. Revel in big-speaker performance, near-invisibility, and superior ease of installation.

Powerful Bass, Dynamic Mids

From an 8” Composite Mineral-filled Polypropylene Driver Cone.

Swivel Tweeter

For Precise Direct Sound or Diffuse Surround Sound on the DT 8R.

High-Definition Crossover

For Superior Transparency.

Definitive Audio Performance: A Top Performer, All Around

Bold and powerful, the DT 8R features an 8” Woofer and 1” Pivoting Dome Tweeter in a round form factor engineered for in-ceiling audio excellence. Every component in the DT 8R is conceived and developed in-house for a listening experience that delivers and a product that endures.

High-Performance Audio Components in your Walls and Ceilings

Teeming with high-tech components such as annealed aluminum tweeters, polypropylene mineral-filled mid/bass cones, and anti-diffraction surfaces, the DT Series reproduces audio with the legendary voicing you’ve come to expect from Definitive Technology.

Pure Aluminum Swivel Tweeter

The ultralight, rigid construction of the DT 8R’s aluminum dome tweeter enables it to play significantly higher frequencies than we can hear, allowing for optimum linearity within the range of human hearing. The swivel mechanism lets installers orient the tweeter for precise direct sound or diffuse surround sound- or anything in between.

Quick and Easy Installs: Truly Custom Installations

Using only four common tools and a pencil, installers will find it a breeze to install the DT 8R. With strong yet lightweight construction, integrated pivoting lock arms, paintable grilles, and magnetic grille fasteners, you’ll have your DT 8R installed and playing sweet audio in no time.

Pivoting Tweeters for Customized Sound

When using DT8R as front speakers in a home theater setup or as stereo speakers in a distributed audio system, installers can aim the tweeter toward the main listening position for improved imaging and detail. When using as rear/surround speakers, installers can aim the tweeter toward an adjacent wall or ceiling for a more diffuse sound field.

Fewer Tools Needed for Faster Installs

Rotating lock arms, magnetically-attached grilles, and heavy-gauge speaker wire push terminals enable a faster, simpler installation using fewer tools.

Paintable Magnetic Grilles for the Custom Touch

All DT 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.
