The QSC AD-C.SUB is part of the AcousticDesign™ Series SUB/SAT loudspeaker solution, which is ideally suited for background music applications that require depth and clarity even at lower volume settings. The AcousticDesign Series SUB/SAT loudspeakers are specifically designed to be mix-and-match capable; meaning any combination of satellites may be paired with any subwoofer in the AD Series SUB/SAT line.
