General
The QSC KS118 is an active subwoofer with multiple setup options including omni-directional or cardioid radiation modes. To set up the cardioid radiation, two KS118 bins are needed. In a single sub installation, the installed 18-inch woofer will still produce thunder and rattle rib-cages, making it a significant addition to any composition. The KS118 is powered by a class D amplifier that can achieve a ground-shaking peak of 3600 Watts. Like its sound, this subwoofer is incredibly heavy, but comes with a highly convenient, full set of wheels.
