Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at 585-328-8181 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

Our Best Freestanding Speaker TechnologiesInvisible Audio, Astonishing Performance

The culmination of decades of engineering, DI Series Loudspeakers deliver sensational sound quality while virtually disappearing into walls and ceilings with our hidden flange design. Treat yourself to dynamic bass, smooth midrange, and sparkling treble with little impact on your décor.

Image Feature

Pivoting Tweeter

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 3.5R features a pivotable tweeter for clean, sparkling, distortion-free highs, with dispersion customizable to your space.

Image Feature

Exclusive BDSS™

For more bass in less space while keeping midrange detailed and responsive, the DI 3.5R's 3.5" mid/bass woofer leverages our exclusive Balanced Double Surround System (BDSS™) driver technology. The double butyl rubber surrounds produce a much greater cone excursion than other comparably sized drivers. And the DI 3.5R's rigid PolyStone™ basket provides a sturdy launching pad for the powerful excursion.

Acoustic Wizardry

The DI 3.5R features a sophisticated adjustable crossover network with custom, high-precision components for superior sonic purity.

Disappearing DesignInstalls 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.

Image Feature

All the Stealth

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.

Image Feature

Paintable Magnetic Grille

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.

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.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
