The QSC RSB212 is a dual 12-inch reference-monitor subwoofer designed to partner with QSC RSC screen-channel loudspeakers in high-performance cinema and screening-room systems. It handles the low-frequency and effects content behind the screen, delivering the extended, high-output bass required for accurate reference monitoring. As a passive cinema subwoofer it is powered and processed by an external amplifier/DSP (such as a Q-SYS cinema amplifier), and it connects using QSC's cinema wiring conventions (NL-series connectors). It is a standalone loudspeaker enclosure, not an accessory.
