The KSub — a member of QSC’s K Series — offers impressive sound quality, high wattage, and relatively light weight in an easy to transport package. Engineered by QSC’s amplifier engineer team under the direction of Pat Quilter, the KSub incorporates new Class D power modules with extensive DSP processing employed throughout. The end result is a subwoofer that defies expectations based on its size and weight. The combo XLR and 1/4″ inputs can handle either mic or line-level inputs, making the KSub a great addition to your rig. As an added bonus, the KSub comes with a threaded speaker mounting pole.
