The KS Series, QSC's New Generation

Backed by over fifty years of the brand's expertise in professional sound reinforcement, the range focuses on performance, reliability, and versatility for both rental companies and fixed installations.
Who Is It For and What Are Its Uses?
Ideal as front-of-house reinforcement, the KS118 targets theaters, clubs, event professionals, artists, and rehearsal spaces seeking massive, clean, and controlled bass. Its XLR connectivity simplifies integration into a modern sound system chain, whether with full-range speakers or within an existing QSC setup.

Designed for touring, it features two 35 mm sockets with M20 threading for pole and satellite installation, as well as two handles for safe handling despite its 47 kg weight. Its discreet black finish allows for seamless integration on stage or in fixed installations.
