QSC SB-2180 Subwoofer with Dual 18" Transducers, 1100Ws Power

Designed for professional AV, cinema and monitoring environments, the QSC SB-2180 pro subwoofer delivers powerful, accurate low-frequency performance where intelligibility and impact matter most. This QSC pro subwoofer uses dual 18" transducers to produce deep, controlled bass that supports dialogue, low-end effects and critical listening in theaters, control rooms and surveillance monitoring suites. With an extremely narrow enclosure — less than 17 inches behind the screen — the SB-2180 installs where space is limited without sacrificing output. The folded port design preserves full port length and internal volume for extended LF response, while the high-output amplifier configuration provides substantial power handling (1100W per driver, 2200W total RMS) for reliable, distortion-resistant performance. Durable screw-type barrier-strip connectors and a commercial-grade black finish make it straightforward to integrate into installed sound, security monitoring and surveillance audio systems. Choose the SB-2180 when you need theater-level bass, compact installation footprint and dependable commercial reliability.
