Balanced Double Surround System

Proprietary BDSS™ technology delivers the wide dynamic range and deep bass output of much larger drivers in a small-sized, high-efficiency mid/woofer.

Balanced Dispersion

BDSS™ technology, aim-ready tweeters and a specially-contoured AeroRing™ around the driver distributes natural, well-balanced sound everywhere in the room.

Designed for Invisibility

With a minimal visible surface area, hidden flange architecture and micro-perf grille, the DI 5.5 LCR disappears into any environment, without the need for custom sheetrock or spackle work.
