Looking for powerful low-end performance that doesn’t overwhelm your stage or venue with unwanted bass? The QSC KS212C is a revolutionary subwoofer that combines cutting-edge technology with convenience in one sleek, portable enclosure. This is the world’s first single-box powered cardioid subwoofer—designed specifically for mobile performers, production professionals, and intimate venues that demand tight, controlled bass without sacrificing punch or clarity.

With an earth-shaking 3600 Watts of Class D power, the KS212C is engineered to “keep bass in its place.” Whether you're setting up for a DJ event, corporate function, or a small live gig, this sub is your secret weapon to deliver clean, directional low-end without flooding the entire room—or worse, the stage—with unwanted rumble.

Features that Set the KS212C Apart:

  • Single-box cardioid design:
    Unlike traditional subs that radiate sound in all directions, the KS212C delivers a remarkable 15 dB SPL attenuation from front to rear. That means crystal-clear low-end for your audience—and less noise on stage or off-axis areas.

  • Dual 12” long-excursion drivers in 6th-order bandpass chambers:
    These specially arranged drivers ensure efficient, deep, and punchy bass that stays focused where you need it.

  • 3600 Watt Class D Amplifier with advanced DSP:
    Get consistent, high-output performance with built-in processing that optimizes sound in any environment.

  • Flexible and installation-ready:
    With two M20 threaded pole sockets (top and side), you can orient the sub vertically or horizontally to fit your space or configuration.

  • Portable and road-ready:
    Despite its powerful output, the KS212C remains mobile. At just 88.5 lbs, it features heavy-duty, low-noise casters and rugged aluminum handles to make setup and teardown a breeze.

  • Compact footprint:
    HxWxD = 24.5” x 15.5” x 33.5” – powerful yet space-efficient, ideal for tight stages or mobile systems.

Whether you’re a touring DJ tired of muddy bass behind your booth, or a venue installer looking for powerful sub performance with controlled coverage, the KS212C will exceed expectations.
