The QSC KS118 is a high-output powered subwoofer built for events that demand serious low-end. With an 18” long-excursion woofer and 3600 W peak power from a Class-D amplifier, it delivers tight, controlled bass with force and clarity.
This subwoofer reaches a frequency response of 41 Hz to 98 Hz (-6 dB) and extends down to 35 Hz (-10 dB). It hits a maximum SPL of 136 dB, ensuring deep and impactful low frequencies that energize every venue. Whether you’re supporting a large LED wall at an exhibition or driving sound at a live show, the KS118 makes every beat count.
To further enhance performance, the selectable DEEP™ mode boosts extremely low frequencies. As a result, it becomes a perfect fit for demanding applications – corporate events, product launches, and immersive audiovisual setups.
Installation is simple and efficient. The QSC KS118 offers dual XLR/TRS combo inputs, XLR loop-thru outputs and a standard IEC power input. It integrates seamlessly with full-range tops and other subwoofers. Thanks to its 18 mm birch cabinet, four robust casters and ergonomic handles, the unit is road-ready and quick to deploy.
