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. 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.
