Product Overview

Overview

The QSC AD-P.SUB is a 6.5-inch pendant-mount subwoofer that drives up to four satellite speakers from its built-in filtered outputs. It is the bass half of the AcousticDesign subwoofer-and-satellite business-music range: a 6.5-inch dual-voice-coil woofer hanging from the ceiling, with a 70 V or 100 V transformer and four built-in high-pass outputs that feed the satellites. That means one amplifier channel and one wiring run for a full-range ceiling system.
