The QSC SC-1120 is a compact, high-performance two-way passive screen channel loudspeaker designed for small cinema rooms up to 35 feet in depth. Featuring a 12 inch woofer with a 2.5 inch voice coil and a 1.75 inch compression driver mounted on a 90 degree axisymmetric horn, the SC-1120 delivers full-range clarity and consistent coverage across the seating area.
Its single-enclosure design requires less than 12 inches of depth behind the screen, making it ideal for space-constrained installations. The passive crossover allows for single-channel amplification, simplifying system integration. Built with a durable MDF enclosure and finished in non-reflective black vinyl, the SC-1120 offers professional-grade performance in a compact footprint.
