Capable of room-filling output down to 35 Hz, it covers the lowest octaves with authority. Omni and cardioid modes allow you to optimize coverage for your application. Convenient presets, adjustable parameters and onboard DSP ensure optimized performance. The rugged enclosure stands up to heavy use with casters for easy mobility.

3,600W of Power Drives Monstrous Lows
With a built-in 3,600W Class D amplifier, the KS118 generates tremendous SPLs even at the lowest frequencies, giving your mixes and playback huge low end punch. The long-excursion 18" woofer reproduces clean, musical bass with minimal distortion even when pushed hard. Peaking at 136dB peak SPL, this powerhouse delivers seismic lows that you can feel.
Omni and Cardioid Modes for Versatile Coverage
The KS118 offers both omnidirectional and cardioid coverage patterns. Omni mode spreads bass evenly across a wide area, while cardioid mode focuses output forward in a tighter pattern. With the ability to array two KS118s in cardioid mode, you can put serious low end directly where you need it. The adjustable coverage gives you flexibility for mobile gigs, installed AV and clubs.
Onboard DSP Dials in Your Sound
Built-in DSP ensures optimized performance while letting you easily adapt the KS118 to your application. Convenient presets provide one-touch setup for common scenarios. Adjustable parameters like crossover, delay and DEEP mode allow extensive customization. The DSP protects the woofer from damage while providing the processing power to maximize your low-end impact.
Built Tough With Casters for Easy Mobility
The KS118 is built road-tough to handle real-world use and abuse. The 15mm birch plywood enclosure and powder coated steel grille stand up to heavy wear. Four casters make it easy to roll the 132 lb. sub in and out of venues and setups. An M20 pole socket allows convenient stacking above a sub. With the included padded cover, your KS118 investment stays protected during transport and storage.
