The KS 112 is a seriously potent little subwoofer – QSC really nailed the compact, high-performance design. It's ideal for DJs, smaller bands, or anyone needing deep, clean bass in a tight space, like mobile rigs or bars. The birch ply build feels rock solid and the DSP makes it surprisingly forgiving.

Frequently Asked Questions
It punches significantly harder than most comparable subs due to the Class D amp and efficient bandpass design; the DSP is a major advantage for clean output.
The variable speed fan is designed for low noise, but in very quiet acoustic sets, it might be subtly audible – it's far less intrusive than older QSC designs.
While it’s powerful, a solo performer might benefit from a satellite speaker system to cover the higher frequencies, though the KS 112 will add a substantial low-end foundation.
