The QSC SC-433C is a THX-approved three-way behind-the-screen cinema loudspeaker in QSC's SC-400 (Digital Cinema Sound) series. It uses a triple-15-inch low-frequency section for very high output and deep low-end headroom, targeting large auditoriums. The cabinet mounts behind a perforated projection screen and can be bi-amplified or tri-amplified for scalable amplifier and DSP deployment.
