Product Description

Line Circle

Powerful far beyond its diminutive size, the DI 5.5BPS delivers captivating surround sound with the bass output and dynamic range of traditional 8" speakers. Hidden within your walls or ceiling, its lifelike sonic performance and broad, even dispersion become even more impressive. While other in-wall speakers fall short in sound quality and stealth, the DI 5.5BPS sets an impossibly high standard.

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.

The DI 5.5BPS boasts Definitive Technology’s vaunted Bipolar technology, filling the room with a perfect combination of direct and reflected sound for stunning surround effects.

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.

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 5.5BPS features pivotable tweeters for clean, sparkling, distortion-free highs, with dispersion customizable to your space.

For more bass in less space while keeping midrange detailed and responsive, the DI 5.5BPS’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 its 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.

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

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

The Axially-Aligned configuration of each DI 5.5BPS  tweeter with its companion woofer provides broader sound dispersion and more natural balance.

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.

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.
