Powerful performance is practically invisible with the Definitive Technology Disappearing™ Series. With a minimal 7.38” x 7.38” grille, the DI 5.5S is remarkably smaller than competing 6.5” models but offers much more in terms of technology and sound quality. From its 5.25” BDSS™ driver and 1” pure aluminum tweeter to the high definition crossover and exclusive AeroRing™, this in-wall side/rear surround speaker conceals tremendous tonality within its tiny dimensions.

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.

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

Pure Aluminum Tweeter
The pivoting pure aluminum dome tweeter features a uniquely constructed housing, eliminating diffraction distortions typical with traditional speakers for spectacular audio performance.

Adjustable Crossover
A sophisticated adjustable crossover network with custom, high-precision components produces superior sonic purity for crisp, clean sound.
