QSC AD-C.SUB 6.5-Inch Small-Format Passive Ceiling Subwoofer White - B-STOCK

Passive In-Ceiling Subwoofer for Professional Background Music Systems

The QSC AD-C.SUB is a small-format passive ceiling subwoofer designed for professional background music applications that require refined low-frequency depth and clarity, even at lower volume settings. Finished in white and built for in-ceiling installation, it provides a compact bass solution for distributed audio and commercial installed sound systems.

The AD-C.SUB features a 6.5-inch dual voice-coil weather-treated paper cone woofer designed for improved thermal dissipation and higher output. It delivers a 45 Hz to 150 Hz effective frequency range, 100W rated power handling, 86 dB sensitivity, and maximum output up to 111 dB peak. A low-saturation, low-loss 70/100V transformer provides selectable taps and a 4-ohm bypass for flexible system configuration.

Four built-in high-pass filtered outputs allow the AD-C.SUB to connect with up to four QSC AcousticDesign SUB/SAT satellite loudspeakers. This design can reduce setup time, amplifier channel requirements, and wiring complexity while supporting mix-and-match combinations of subwoofers and satellites within the AcousticDesign SUB/SAT line.

Locking 4-pole Euroblock connectors, a removable conduit cover plate, four long-travel dog-ear blind mounts, and a snap-fit magnetic powder-coated steel grille support professional ceiling installation. Intrinsic Correction voicings are available through MP-M Series mixers and the Q-SYS Platform.
