Exceptional Speakers Can Hide, Exceptional Sound Can’t

High performance is practically invisible with the Definitive Technology Disappearing™ Series. The sleek profile and vanishing in-wall mounting design allows the DI 6.5R to fill any room with immersive sound, not bulky speakers. The outstanding, nuanced audio detail is instantly conspicuous, while the speakers stay ingeniously out of sight.

Key Features

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.

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.

Balanced Dispersion

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

Adjustable Crossover

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