The QSC KS212C Active subwoofer represents the world’s first-in-class single-box active 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.

- Two M20 threaded sockets (one on top, one on side) accept 35 mm speaker pole
- Four low-noise, heavy-duty casters
- HxWxD = 24.5-inch x 15.5-inch x 33.5-inch (622 x 394 x 851 mm)
- Net Weight: 40.1 kg (88.5 lbs)
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 35 mm loudspeaker pole in either horizontal or vertical orientation.
Most subwoofers radiate energy around the entire enclosure, leading to undesirable LF build-up on stage and wasted energy around the sides and rear of the system.
The KS212C subwoofer keeps “bass in its place” with a single-box cardioid array that produces an amazing 15 dB more output at the front than at the rear.
