QSC KS118 18" 3600W Active Subwoofer -18" SKU# KS118

The QSC KS118 is a high-output active subwoofer well suited for mobile entertainment, AV rental, event production, clubs, and performance venues. The 18" direct radiating driver is powered by a 3600W Class-D amplifier, which delivers high sound pressure levels with dynamic and musical sound reproduction of very-low frequencies.

The onboard DSP allows the user to save and recall variable delay and crossover settings, all the while protecting the system. Additionally, two KS118s can be deployed in a cardioid arrangement, which maximizes low-frequency output from the front, while minimizing energy around the sides and rear of the setup.

The KS118 is highly portable with four, rear-mounted, low-noise casters. The birch enclosure is rugged yet stylish and features comfortable aluminum handles and a top-mounted M20 threaded pole receptacle accepts a 35mm pole for easy vertical deployment with K.2 Series and other full-range loudspeakers.
