Introduction
The SB-1180 extends QSC’s commitment to the cinema market by offering high-quality QSC sound for small room systems. Part of the DCS Digital
Cinema Speaker Series, the SB-1180 subwoofer offers a unique solution that addresses the extended low frequency requirements of E-Cinema or
D-Cinema in small room applications.
The SB-1180 features a single 18-inch (457 mm) woofer with 4-inch (102 mm) voice coil for extended bandwidth low frequency reproduction. With
an enclosure depth of less than 12 inches (300 mm), the SB-1180 is one of the narrowest subwoofers available, which dramatically reduces space
requirements behind the screen.
