Product Description
The KS118 is a very high output active subwoofer producing impressive low frequencies for mobile entertainment, AV production, clubs and performance venues. Featuring an 18-inch direct radiating driver powered by a 3600 Watt Class D amplifier, the KS118 delivers high sound pressure levels with dynamic and musical sound reproduction of very low frequencies.

On-board DSP optimizes and protects system performance as well as offers advanced capabilities such as the ability to array two units in a cardioid arrangement. Highly transportable, the rugged enclosure features comfortable handles and four low noise casters. An M20 threaded pole receptacle accepts a 35 mm pole for easy vertical deployment with full-range loudspeakers.
