Product Description
The QSC KS118 is a premium high-output 18-inch powered subwoofer engineered for professional AV, live events, DJs, and performance venues. Featuring a powerful 3600W Class D amplifier and a long-excursion 18" driver, the KS118 delivers deep, dynamic, and musical low frequencies with exceptional clarity and impact.
Designed with advanced onboard DSP, the KS118 provides intelligent system optimization, protection, and flexible configuration options. Users can select between omni-directional or cardioid modes (with multiple units) to control low-frequency dispersion—maximizing output to the audience while reducing unwanted rear energy.
Built for real-world use, the KS118 features a rugged birch enclosure, ergonomic aluminum handles, and low-noise casters for easy transport. With its M20 threaded pole mount and compatibility with full-range systems like QSC K.2 series speakers, this subwoofer integrates seamlessly into professional setups.
