    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.

    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.
