Powerful bass with flexible Bluetooth audio integration.
For larger low-frequency demands, the QSC CS18 18" 2600W powered subwoofer adds an 18" direct-radiating driver to the CS Series lineup. Its Class-D amplification delivers 2600W peak power and up to 134dB maximum rated SPL, with a DEEP preset for added low-frequency extension. Bluetooth 5.1 audio streaming and control through the QSC Loudspeaker Control app expand system flexibility, while the Custom Output Connector allows Bluetooth audio to feed compatible powered speakers without built-in Bluetooth, including QSC CP Series models. Quick Cardioid deployment for setups using at least two subwoofers gives DJs, bands and event professionals additional control over low-frequency coverage.
18" Driver and 2600W Class-D Amplification
The CS18 combines an 18" direct-radiating driver with a 2600W peak Class-D amplifier to deliver dedicated low-frequency reinforcement for live sound and event production. Its standard frequency response extends from 46Hz–96Hz at -6dB, while engaging the DEEP preset extends the low-frequency response to 39Hz. A painted birch plywood enclosure provides a durable foundation for portable applications. With its larger driver and extended low-frequency reach, the CS18 is suited to PA configurations where substantial bass reinforcement is a priority.
Bluetooth Audio Routing and Flexible Low-Frequency Control
Bluetooth 5.1 audio streaming gives the CS18 a wireless playback option, while True Wireless Stereo connectivity supports compatible stereo system configurations. Through the Custom Output Connector, Bluetooth audio can also be routed to compatible powered loudspeakers that lack built-in Bluetooth, such as QSC CP Series models. The QSC Loudspeaker Control app provides additional adjustments over Bluetooth, complementing the rear-panel gain and selection controls. A DEEP preset adds low-frequency extension, while Quick Cardioid deployment supports directional bass coverage when at least two compatible CS subwoofers are used.
Flexible Connections and Road-Ready System Deployment
Two locking XLR/1/4" combo inputs and two XLR outputs with loop-through and post-DSP routing accommodate different loudspeaker configurations. An M20 threaded pole mount supports compatible speaker poles, while the universal 100–240V power supply accommodates different electrical environments. The rugged painted birch plywood enclosure is built for portable applications, with a net weight of 82.9 lb. Tuned for integration with QSC C Class loudspeakers and compatible with K Series systems, the CS18 supports expandable PA setups for live performances and event production. Add dedicated low-frequency reinforcement to your sound system with the QSC CS18 18" 2600W powered subwoofer.
