DI 5.5R - Disappearing™ Series Round 5.25" In-Wall Loudspeaker

With its small diameter, hidden flange design, and low-profile grille, the DI 5.5R is nearly invisible in your ceilings or walls. This pint-size dynamo goes boldly where other speakers can’t, while producing a full, accurate audio experience belying its size.

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 5.5R features a pivotable tweeter for clean, sparkling, distortion-free highs, with dispersion customizable to your space.

Exclusive BDSS™ Technology midrange/bass woofer

For more bass in less space while keeping midrange detailed and responsive, the DI 5.5R’s 5.25" 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 5.5R’s rigid PolyStone™ basket provides a sturdy launching pad for the powerful excursion.

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

Acoustic Wizardry for the details that make the difference

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

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

The Axially-Aligned configuration of the tweeter with the woofer provides broader sound dispersion and more natural balance.

Installs Easily and Reliably

Whether new or existing construction, walls or ceilings, residential or commercial, DI Series speakers offer simple, stealthy installations. From pivoting lock arms to paintable grilles and frames to sure-grip magnetic grille fasteners, DI Series speakers are installer-friendly to the extreme.

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.

Expert Insight

Line Circle

“If you’re building a home theater system and a nearly invisible, zero-floor-space design is your goal–but you don’t want to sacrifice sound quality and aural impact–I highly recommend the DI Series from Definitive Technology. The speakers’ build quality and attention to detail are excellent. We are talking about way more than bang for the buck here, although the value is extremely high...prepare to be wowed. I was!”
