Revolutionary cardioid technology meets portable design in the groundbreaking KS212C subwoofer, delivering professional-grade bass management in a single, compact enclosure. This world-first powered cardioid subwoofer solution transforms how mobile entertainers, AV professionals, and performance venues handle low-frequency control, effectively "keeping bass in its place" where it belongs.
The powerhouse 3,600 Watt Class D amplifier drives dual 12-inch long excursion drivers, each housed within precision-engineered 6th order bandpass chambers. Advanced DSP processing ensures optimal performance whilst delivering an impressive 15 dB greater output at the front compared to the rear, making unwanted stage bleed and venue spillage a thing of the past.
Built for the demands of professional touring and installation work, the KS212C combines serious performance with practical portability. Comfortable aluminium handles and four heavy-duty, low-noise casters make transport effortless, whilst dual M20 threaded sockets accommodate 35mm speaker poles in both horizontal and vertical orientations. At just 40.1kg and measuring 622 x 394 x 851mm, this compact unit delivers maximum impact without the bulk traditionally associated with cardioid subwoofer systems.
