QSC introduces the CS15 and CS18, two new CS Series powered subwoofers that combine powerful bass with excellent portability!
The CS15 features a compact 15-inch woofer, while the CS18 offers higher output with an 18-inch woofer. Both models feature a Class D amplifier delivering up to 2,600 watts of peak power. Paired with C Class loudspeakers, they make it easy to build a system with powerful, impactful low-frequency performance.
Alongside the DEEP™ preset, which enhances bass extension and impact, both models include a Quick Cardioid preset that lets you control low-frequency directivity using two or more subwoofers. Settings can be adjusted quickly via the simple, intuitive rear panel, while the QSC Loudspeaker Control app provides wireless control of various functions via Bluetooth.
Both models also feature two XLR inputs, direct pass-through/assignable outputs, and an M20 threaded speaker pole mount. Their wooden enclosures feature a durable painted finish and are designed for easy transport and setup. Ideal for DJs, live shows, events, band performances, and installed sound systems, the CS15 and CS18 deliver enhanced bass for a wide range of applications.
