Invisible 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.
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 4.5R 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 4.5R’s 4.5” mid/bass woofer leverages 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 4.5R’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 4.5R 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 midrange/woofer provides broader sound dispersion and more natural balance.
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.
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.
