QSC KS112 2000W 12" Compact Powered Subwoofer

The QSC KS112 is a compact, tour-ready powered subwoofer that concentrates serious low-end punch into a portable footprint. Its 12-inch long-excursion driver works inside a 6th-order bandpass enclosure and is driven by a 2000W Class-D amplifier to deliver authoritative bass with headroom, hitting 128 dB peak SPL for confident coverage in small to mid-size rooms. QSC’s Intrinsic Correction loudspeaker management optimizes response, while onboard DSP provides a variable crossover and savable scenes for fast, repeatable setups across different rigs. Whether you’re building a portable PA for live bands, DJs, or corporate A/V, KS112 slots in neatly beneath tops and keeps the mix tight and musical.

Road sense shows up everywhere: the birch plywood cabinet is rugged and refined, and four low-noise casters make roll-in painless. Two dual M20 pole mounts enable vertical or horizontal deployment with a threaded pole for rock-solid stability. Connectivity is straightforward—dual locking XLR/TRS combo inputs and dual XLR loop-thrus—so integrating with common front-of-house workflows is easy. At 24.5 × 15.5 × 24.25 inches and 62.6 lb, it’s sized for real-world transport without sacrificing performance. Registering within 30 days activates a 6-year warranty, underscoring QSC’s reliability focus.

From club installs and worship spaces to mobile event companies and rental houses, KS112 delivers deep, dynamic low-frequency extension in a footprint you can actually move. Pair it with K.2 tops for a scalable, voiced-together system, or drop it into an existing rig to add clean, controlled punch. This is compact subwoofer design done right: smart DSP, stout construction, and gig-friendly ergonomics that keep the sound strong and the load-in civilized.
