    Our Best Freestanding Speaker Technologies

    Environmental EQ
    fine-tunes the highs for 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.

    Pivoting Tweeter
    for controlled directivity

    The ultralight, rigid construction of DI Series aluminum dome tweeters enables them to play significantly higher frequencies than we can hear, enabling optimum linearity within the range of human hearing. The DI 5.5LCR features a pivotable tweeter for clean, sparkling, distortion-free highs, with dispersion customizable to your space.

    Exclusive BDSS™
    midrange/bass woofers

    For more bass in less space while keeping midrange detailed and responsive, the DI 5.5LCR’s two 5.25” mid/bass woofers leverage our exclusive Balanced Double Surround System (BDSS™). The double butyl rubber surrounds produce a much greater cone excursion than other comparably sized drivers. And the DI 5.5LCR’s rigid PolyStone™ basket provides a sturdy launching pad for the powerful excursion.

    With BDSS drivers, you’ll enjoy superior midrange and midbass dynamics and detail in packages sized for stealth.

    Acoustic Wizardry
    for the details that make the difference

    The DI 5.5LCR features a sophisticated adjustable crossover network with custom, high-precision components for superior sonic purity.

    Surrounding the BDSS drivers are a specially-contoured AeroRing™ that precisely distributes natural, well-balanced sound by minimizing diffraction.

    Disappearing Design

    Installs Easily and Reliably

    Whether new or existing construction, walls or ceilings, residential or commercial, DI Series speakers offer simple, stealthy installations. Our engineers have extensive custom installation experience, and have felt your pain when working with hastily-engineered products. From pivoting lock arms to paintable grilles and frames to sure-grip magnetic grille fasteners, DI Series speakers are installer-friendly to the extreme.

    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 install the 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
    installations 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.

    A Disappearing Act
    for every installation

    Whatever the setting—residential or commercial, music room or home theater—DI Series has designed a disappearing act ready to entertain you. From round or square ceiling speakers, to in-wall speakers, to Bipolar surround speakers, to in-wall subwoofers, DI Series is ready to rock a venue of any size—invisibly. Mix and match as you please, confident that you’ll always enjoy Definitive Technology's legendary speaker voicing.

      Manufacturer’s Pricing Policy

      Why do I need to contact you in order to place my order?

      As an authorized dealer for the product you are looking at, is bound by certain agreements with our manufacturer partners in how we display, price and sell certain products.

      Some items may not be able to be advertised below a certain price or any pricing at all and others may not be able to be added to a shopping cart via an “add to cart” button.

      If a competitor’s website has the same product but is not restricting the display/functionality in the same way that you see here on, than that competitor is likely NOT an authorized dealer.

      What does that mean for you as the customer? It is very likely that the manufacturer may not honor your products warranty, or that your product was never intended for the US market to begin with.

      If you have any questions regarding a specific product, please do not hesitate to contact us at (888) 392-4814.
