Commanding Low-End Punch in a Compact Footprint
Designed for precise, musical low-frequency reinforcement, the QSC KS112 powered subwoofer is your go-to solution for tight spaces and mobile setups demanding serious bass. Whether you're a gigging DJ, corporate AV provider, or small-venue installer, the KS112 delivers 2000 watts of deep, responsive output from a highly portable, single 12-inch bandpass design. Ideal for pairing with QSC K.2 Series tops, it offers intelligent DSP tuning, flexible deployment, and tour-ready durability—all in a form factor that rolls in with one hand.
Precision Bass Response in a Compact Housing
The KS112 punches above its size with serious SPL and frequency extension down to 38Hz, all housed in a rugged birch enclosure. It’s ideal for mobile pros and smaller venues where floor space is limited but performance can't be compromised. With onboard DSP, multiple deployment options, and easy I/O, it's equally effective in permanent installations and high-turnover rental fleets.
