Definitive Audio Performance

The In-Ceiling Speaker That Covers It All

The DT6.5STR features dual .75” Pivoting Dome Tweeters and a 6.5” Mid/Woofer and 1” Pivoting Dome Tweeter for clear, detailed stereo or immersive, room-filling surround sound. Every component in the DT Series is optimized for superior quality and sound. And each component is conceived and developed in-house for a listening experience that delivers and a product that endures.

Single-Speaker
stereo solution

The DT6.5STR is ideal for limited-space applications such as hallways, kitchens, bathrooms, and offices. Its innovative configuration  features a stereo setup within a single round ceiling speaker. Bristling with technologies such as dual voice coils powering the mid/bass driver and an innovative dual-angle tweeter configuration, the DT6.5STR produces broad stereo dispersion from just one speaker.

Low-Diffraction Swivel Tweeter
for high-performance high frequencies

The DT6.5STR 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.

Connectivity to fill the whole house with 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 DT6.5STR'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 DT6.5STR in-ceiling speaker. With strong yet lightweight construction, integrated pivoting lock arms, paintable grilles, and magnetic grille fasteners, you’ll have your DT6.5STR 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.
