Invisible Audio, Astonishing Performance

The culmination of decades of engineering, the DI 4.5R delivers sensational sound quality while virtually disappearing into your ceiling. Enjoy dynamic bass, smooth midrange, and sparkling treble with minimal impact on your décor.

Pivoting Tweeter for Controlled Directivity

The ultralight, rigid construction of the aluminum dome tweeter enables it to play significantly higher frequencies than we can hear, enabling optimum linearity within the range of human hearing. The DI 4.5R features a pivoting tweeter for clean, sparkling, distortion-free highs, with dispersion customizable to your space.

Exclusive BDSS™ Midrange/Bass Woofer

For more bass in less space while keeping the midrange detailed and responsive, the DI 4.5R’s 4.5” mid/bass woofer leverages Definitive Technology’s 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

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, Easy Installation

The DI 4.5R is designed for simple and stealthy installations. The hidden flange architecture allows the speaker to virtually disappear into your ceiling, and the paintable grille can be customized to match your décor.
