This 3,600-watt active subwoofer yields extreme output with impressive low-frequency performance. Its 18-inch 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 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 KS118 also includes an M20-threaded pole socket, swivel casters, and a rugged painted wood enclosure.
