The QSC SB-218F is a flyable dual-18-inch cinema subwoofer built for suspended high-output low-frequency reproduction in auditoriums. It provides eight M10 suspension points for overhead rigging and uses two 18-inch, 800-watt transducers (800 W / 1600 W continuous power rating) with 101 dB sensitivity for powerful LFE and screen-channel bass. As a passive cinema subwoofer it is powered and processed by external QSC cinema amplification/DSP. This is a standalone subwoofer, not an accessory.
