QSC KS212C Dual 12" Cardioid Powered Subwoofer

The KS212C subwoofer represents the world’s first-in-class single-box powered cardioid subwoofer solution for highly portable entertainment and installation applications.

A breakthrough in innovation and design, the 3,600 Watt KS212C subwoofer uniquely provides all the benefits of cardioid deployment in a single, compact enclosure. “Keeping bass in its place” for mobile entertainers, AV production and rental professionals, as well as modestly-sized performance venues, the KS212C subwoofer is unparalleled in its ability to manage low frequencies on the stage, or any application where undesirable low-frequency energy needs to be minimized.

Powered by a 3,600 Watt Class D amplifier, processed with the latest DSP technology, and featuring dual 12-inch long excursion drivers each arranged in a 6th order bandpass chamber, these components all combine seamlessly to produce a staggering 15 dB more output at the front of the cabinet than at the rear. Highly portable, the cabinet features comfortable, aluminum handles and four, rear-mounted casters. Two M20 sockets accept a 35mm speaker pole in other horizontal or vertical orientation.
