The QSC AD-C8T-SWZB-WH is an 8-inch zero-bezel ceiling-mount subwoofer designed to deliver powerful, evenly distributed low-frequency reinforcement while maintaining a clean, discreet architectural appearance. Its bass-reflex enclosure and 8-inch low-frequency transducer provide a system bandwidth of 65 Hz–155 Hz at -3 dB, with 92.3 dB sensitivity and up to 113 dB continuous SPL, making it well suited for commercial audio, hospitality, retail, corporate, and other installed sound applications. The passive 125 Hz low-pass design supports seamless integration with AcousticDesign full-range loudspeakers, while 70V/100V transformer taps from 25W to 200W offer flexible system configuration, with an 8O bypass for conventional amplification. The white finish, snap-fit magnetic grille, blind-mount system, and included tile rails and hardware allow for streamlined ceiling installation, while UL1480A, UL2043, and IP-44 ratings support use in demanding installed environments.
