Compact yet powerful active subwoofer from QSC!

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.

Sweetwater Advice

Joseph Secu
QSC does it again! The best way to compliment your K-series mains is to add a few of these. The bass coming from this small module is so powerful and punchy that you won't believe it. You'll just have to buy a few to experience it. I'm a huge fan!

In my live PA rig, I am running a KSub and two K12s. WOW. Three thousand watts of the BEST sound I have ever heard, and it all fits conveniently into the back of my car. Not only is the KSub a thunderous presence, but after the gig, I just flip it onto its castered back, set the two K12's on top, and wheel them out. Teardown at 2:30am has never been easier!

I have 2 of these (Along with 2 k12 tops) and they are AMAZING. Plenty of low end kick, and in a warm, pulse-your-heart way. They deliver the results needed, and sound fantastic.
