The QSC SC-1150 is a high-performance two-way passive screen channel loudspeaker optimized for small cinema rooms up to 45 feet in depth. It features a 15 inch woofer with a 3 inch voice coil and a 1.75 inch compression driver mounted on a 90 degree axisymmetric horn, delivering full-range clarity and consistent coverage across the seating area.
Designed as a single-enclosure solution, the SC-1150 requires less than 12 inches of depth behind the screen, making it ideal for space-constrained installations. The passive crossover simplifies system integration by requiring only one amplifier channel. Built with a durable MDF enclosure and finished in non-reflective black vinyl, the SC-1150 offers professional-grade performance in a compact, installation-friendly footprint.
