QSC KS118 3,600W 18" Powered Subwoofer

QSC is proud to introduce the KS118 18" active subwoofer, a revolutionary powered subwoofer designed to bring thunderous bass to any live-sound application. Featuring a 3,600W Class-D amplifier powering an 18" woofer, the KS118 delivers chest-pounding low end that will electrify audiences. Onboard DSP provides advanced system optimization and protection while allowing users to enable DEEP mode for intensified low-frequency response.

Massive Power and Performance

At the heart of the KS118 is a 3,600W high-powered amplifier that gives this sub the muscle to produce massive low-end performance for any venue. The 18" direct-radiating woofer was engineered to handle the high power and long excursion needed for deep, tight bass reproduction down to 35Hz.

Optimized and Protected

Onboard DSP allows the KS118 to optimize and protect overall system performance. Users can array two units in a cardioid setup to maximize low-end projection in front of the system while minimizing unwanted energy behind. The DSP also provides system protection by monitoring temperature, excursion and voltage to prevent damage.

DEEP Mode for Intensified Low End

For those wanting to push the low-frequency capabilities, the KS118 offers a DEEP mode that redirects more amplifier power to the lowest frequencies, giving the deepest parts of your music far more punch and rumble. DEEP mode is perfect for modern bass-heavy genres of music where deep, chest-pounding bass is a must.

Road-Ready and Built to Last

Despite its power and performance, the KS118 is highly portable thanks to its lightweight yet durable components. The birch cabinet, robust hardware and steel grille are built to handle the rigors of life on the road. Ergonomic handles and casters make loading and transporting the 104 lb. KS118 surprisingly easy for a subwoofer of this size and capability. A standard M20 pole mount allows the KS118 to be deployed with a full-range loudspeaker atop for a high-powered, full-range system.
