The QSC CS15 is a compact powered subwoofer designed to deliver powerful, controlled bass for DJs, live sound reinforcement, and portable PA systems. Featuring a 15-inch low-frequency driver, a 2600W peak Class D amplifier, and up to 133dB maximum SPL, it combines high-output bass performance with easy setup and flexible control. Built-in Bluetooth audio, wireless control through the QSC Loudspeaker Control app, and selectable DEEP and cardioid modes provide versatile low-frequency reinforcement for a wide range of sound applications.
The QSC CS15 delivers powerful low-frequency reinforcement in a compact, portable design. Its 15-inch direct-radiating driver and 2600W peak Class D amplifier produce up to 133dB maximum SPL, providing the bass output needed for DJ performances, live music, mobile entertainment, and installed sound applications. With a standard frequency response of 47 Hz to 100 Hz (-6 dB), the CS15 delivers controlled low-frequency performance, while the selectable DEEP preset extends bass response for applications requiring additional low-end impact.
Designed for convenient setup and operation, the CS15 features an intuitive rear control panel with gain adjustment, selection buttons, and clear status indicators. Its Quick Cardioid preset allows users to configure directional bass coverage with a minimum of two subwoofers, helping manage low-frequency energy in performance environments. The integrated M20 threaded pole mount also allows compatible loudspeakers to be positioned above the subwoofer using an appropriate speaker pole.
Bluetooth audio connectivity adds flexibility for wireless playback, while True Wireless Stereo technology supports low-latency pairing between a music source and compatible loudspeakers. The QSC Loudspeaker Control app provides access to essential settings and advanced loudspeaker functions directly from a mobile device. For wired integration, the CS15 includes two locking XLR/1/4-inch combo inputs and two XLR outputs, including loop-through and post-DSP output connections.
Constructed from 12-15mm birch plywood with a durable painted finish, the CS15 is designed to withstand regular transport and demanding performance environments. A black 16-gauge powder-coated steel grille protects the driver, while convection cooling supports operation without a cooling fan. Measuring 23.1 x 17.7 x 20.4 inches and weighing 58.7 lb (26.6 kg), the CS15 balances substantial bass performance with portability for mobile DJs, rental companies, event production teams, and professional sound applications.
