The QSC KS118 Will Beef Up Your PA with 3,600 Watts of Bass

Does your PA system need a bass infusion? Get the QSC KS118 — it delivers the goods. This 3,600-watt active subwoofer yields extreme output with impressive low-frequency performance. Its 18" long-excursion, direct-radiating driver facilitates exceptional punch while maintaining ample low-end extension.

Need more bass for electronic, dance, or club music? No problem. Activate the QSC KS118’s DEEP mode, and you’ll be shaking the rafters. Setup is a breeze, thanks to an adjustable crossover with savable/recallable scenes for common applications. Too much bass onstage? Just add a second KS118, place it in cardioid mode, and you’ll keep bass in its place. The QSC KS118 also includes an M20-threaded pole socket, swivel casters, and a rugged painted wood enclosure.
