The QSC KS118 delivers extremely high output and deep, powerful low-frequency performance for professional live sound, touring, and installed systems. Powered by a robust 3600W Class-D amplifier, it features an 18-inch long-excursion direct-radiating driver designed for impactful, tight bass response.

The KS118 offers omni-directional or cardioid radiation modes (cardioid requires a minimum of two units) for better stage control and reduced rear low-frequency buildup. Selectable DEEP™ mode extends low-end response even further, while adjustable crossover, delay, and user-saveable Scenes provide flexible system tuning.

Built with a rugged painted wood enclosure and refined professional appearance, it supports vertical or horizontal deployment and includes an M20 threaded pole mount for full-range speaker mounting. Heavy-duty low-noise casters ensure easy transport, with optional transport and security covers available. Backed by a 6-year warranty upon registration, the KS118 is engineered for powerful, reliable low-frequency performance.
