K Cardioid Active 12" Class D 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. 


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 significantly higher output at the front than at the rear. 


Highly portable, the cabinet features comfortable, aluminium handles and four, rear-mounted casters. Two M20 sockets accept a 35mm speaker pole in other horizontal or vertical orientation.
