Product Overview
The QSC AD-S.SUB is a white 6.5-inch dual voice-coil surface-mount subwoofer that adds low-frequency depth to AcousticDesign SUB/SAT background music systems. It mounts to a wall or surface and drives up to four satellites for distributed commercial audio in retail, hospitality, and commercial meeting spaces.

A V-wall bracket, rear cover panel, and locking 4-pole Euroblock connectors support straightforward surface installation and AV system integration.
