About Definitive Technology DT Custom Install

DT Custom Install Series Round 6.5" In-Ceiling Speaker - Superior Sound, All Around
The DT6.5R in-ceiling speaker is purpose-built for multi-room and home theater applications where great performance, minimized visibility, and ease of installation elevate the experience.

• Powerful Bass, Dynamic Mids: From a 6.5" Composite Mineral-filled Polypropylene Driver Cone
• Swivel Tweeter For Precise Direct Sound or Diffuse Surround Sound
• High-Definition Crossover: For Superior Transparency

Definitive Audio Performance

Elevated, Almost Invisible Sound
Bold and powerful, the DT6.5R features a 6.5" Woofer and 1" Pivoting Dome Tweeter in a round form factor engineered for in-ceiling audio excellence. Every component in the DT6.5R is conceived and developed in-house for a listening experience that delivers and a product that endures.

Low-Diffraction Swivel Tweeter: for high-performance high frequencies
The DT6.5R features our low-diffraction swivel tweeter. Its specially-designed housing eliminates cross-driver interference with the midrange driver while improving dispersion and off-axis response. The swivel mechanism enables the installer to aim the tweeter for pinpoint direct audio or diffuse surround sound.

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 DT6.5R'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.

Polypropylene Mineral-filled Midrange/Woofer
Coupled with butyl rubber surrounds, the polypropylene mineral-filled midrange/woofer cone is a superb combination of lightness, stiffness, excursion, and control. The result: quick and punchy bass with smooth and detailed midrange.

Quick and Easy Installs

Truly Custom Installations
Using only four common tools and a pencil, installers will find it a breeze to install the DT6.5R in-ceiling speaker. With strong yet lightweight construction, integrated pivoting lock arms, paintable grilles, and magnetic grille fasteners, you'll have your DT6.5R speakers installed and playing sweet audio in no time.

Pivoting Tweeters for customized sound
When using DT Series speakers as fronts 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.

Affordable Customization for everyone
DT Series is the culmination of years of research and engineering to innovate an affordable in-wall/ in-ceiling speaker line that's Definitive Technology to the core. Equally at home in distributed audio, home theater, and commercial settings, DT Series speakers bring enthralling music, movies, gaming, and background audio to walls and ceilings - with ease and stealth.
