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.

• 3600 Watt Class D power module 
• Dual 12-inch long excursion drivers; Dual 6th order band-pass design 
• 15 dB SPL attenuation front-to-rear  
• Two M20 threaded sockets (one on top, one on side) accept 35 mm speaker pole 
• Four low-noise, heavy-duty casters 
• HxWxD = 24.5” x 15.5” x 33.5” (622 x 394 x 851 mm) 
• 88.5 lbs (40.1 kg) 

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.

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.
