QSC KS118 3,600W 18" Powered Subwoofer

The QSC KS118 is a very high-output active subwoofer producing impressive low frequencies for mobile entertainment, AV rental, event production, clubs and performance venues. Featuring an 18" direct-radiating driver powered by a 3,600W Class-D amplifier, the KS118 delivers high sound-pressure levels with dynamic and musical sound reproduction of very low frequencies.Onboard DSP optimizes and protects system performance while also offering advanced capabilities, such as the ability to array two units in a cardioid arrangement, maximizing low-frequency output in front while minimizing unwanted energy around the sides and rear of the system. Users can select DEEP mode for extremely low-frequency extension. In DEEP mode, the KS118 redirects more amplifier power to the lower end of the frequency range, which gives the deepest part of your music a lot more punch.Weighing in at only 104 lb., the KS118 is surprisingly easy to maneuver and load. This is due, in large part, to ergonomic aluminum handles and rear-mounted, low-noise casters. A top-mounted M20 threaded pole receptacle accepts a 35 mm pole for easy vertical deployment with K.2 Series and other full-range loudspeakers.Just like its predecessor, the KW181, the KS118 active powered subwoofer lives up to QSC’s reputation for quality workmanship and reliability. It features a rugged birch cabinet, robust hardware and internal components, and tough steel grille to protect the driver. Make no mistake—the KS118 is built for professional use.Mobile DJs will appreciate the powerful output of this rugged subwoofer. Much of today’s popular dance, electronic and hip-hop music relies heavily on ultradeep bass. Whether you’re DJing a wedding, corporate event or spinning in a night club, modern music demands a professional subwoofer. A portable PA system without a powered sub isn’t faithfully reproducing the music the way it was intended. Giving your audience the bass they want to hear and feel requires a quality subwoofer. A live sound system isn’t complete without it.
