The QSC KS212C K Cardioid Dual 12" powered subwoofer delivers thunderous low end in a roadworthy package. This innovative powered sub is ideal for mobile performers, DJs and anyone seeking studio-quality bass in a portable form factor. Sporting dual 12" long-excursion drivers and a cardioid dispersion pattern, the KS212C provides tight, accurate bass response and maximized output.

Dual High-Excursion 12-Inch Woofers for Chest-Thumping Lows

At the heart of the KS212C are two custom-designed 12" long-excursion drivers engineered to handle 3600W of power and move tons of air, each arranged in a 6th order band pass chamber. This allows for 15dB more output at the front of the cabinet than at the back. The woofers' stiff, lightweight cones and butyl rubber surrounds allow for an impressive frequency response down to 30Hz for rich, full bass.

Cardioid Dispersion Minimizes Wall Interference

The KS212C features a cardioid dispersion pattern, with a narrow coverage area towards the front and broad coverage to the sides and rear. This focused output reduces interference from walls and other surfaces, resulting in tighter low-end response and maximized bass clarity, even in small rooms. The cardioid design also allows multiple KS212C's to be stacked together without comb filtering or phase cancelation issues.

A Roadworthy Sub

Weighing in at 88 pounds, the KS212C's rugged cabinet is covered in QSC's signature scratch-resistant, black-textured finish and protected by metal grilles. Recessed handles on the sides and a pole mount receptacle on the bottom provide flexible mounting options on stage or in the DJ booth.

Intuitive Back Panel Controls

A back-mounted LCD panel offers simple control over the KS212C's parameters. Adjust the crossover frequency, polarity and limiter threshold to perfectly match the sub to your main speakers. There are also XLR, TRS and RCA inputs as well as XLR loop-thru outputs. Power the KS212C via the IEC cable and you're ready to unleash its thunderous low end.
