The QSC KS112 powered subwoofer delivers the low-frequency punch of a much larger unit in a highly portable package, proving you don't need a forklift to bring the bass. It's a powerhouse designed for musicians, mobile DJs, and AV professionals who demand premium, heavy-hitting sound without the punishing weight.
Big Sound, Small Package
It's a common misconception that deep, chest-thumping bass requires a cabinet the size of a commercial refrigerator. The KS112 shatters that myth. Armed with an absurdly efficient 2000-watt Class D amplifier, this compact titan drives a single 12-inch transducer through a clever 6th-order bandpass design. The result is a tight, thunderous low-end that fills the dancefloor without devouring your stage space.
2000-Watt Class D Amplifier: Massive, highly efficient power keeps your low frequencies loud, clear, and distortion-free all night long.
12-Inch Long-Excursion Driver: Pushes plenty of air to deliver deep, resonant bass notes your audience can actually feel in their chests.
6th Order Bandpass Design: Maximizes acoustic output in an ultra-compact form factor, giving you maximum boom for a remarkably small footprint.
The Brains Behind the Bass
Raw power is dangerous without a little discipline. That is why QSC loaded this subwoofer with intelligent onboard DSP. It constantly calculates, calibrates, and corrects the sound to ensure optimal performance from the first beat to the final encore. You can quickly dial in your exact crossover settings and save your favorite configurations for different venues, taking the guesswork out of getting great sound.
Intrinsic Correction Tuning: Advanced loudspeaker management constantly protects internal components and maximizes sonic performance, ensuring you never push the driver past its limits.
Savable and Recallable Scenes: Instantly load your preferred settings for commonly used applications, cutting your setup time in half.
Variable Crossover: Seamlessly blend your low frequencies with your top boxes, optimizing the entire system—especially when paired with QSC K.2 Series loudspeakers.
Built for the Brutal Road
Gigging is a grueling gauntlet. Your gear needs to survive tossed vans, tight load-ins, and the occasional careless stagehand. Encased in a premium, painted birch wood cabinet, the KS112 is a rugged road warrior ready for real-world abuse. Factor in the smooth-rolling, low-noise casters, and packing up the van suddenly becomes the easiest part of your night.
Premium Birch Cabinet: A rugged, painted wood enclosure ensures lasting durability while maintaining a refined, professional appearance for high-end corporate gigs.
Dual M20 Speaker Pole Fittings: Deploy the subwoofer in either a vertical or horizontal position, securing a positive, wobble-free connection for your top speakers.
Heavy-Duty Casters: Low-noise casters come pre-installed, sparing your spine the agonizing ache of carrying heavy gear across a massive venue parking lot.
The Bottom Line
The QSC KS112 Powered Subwoofer perfectly blends brilliant engineering with brutal bass. It delivers the heavy-hitting low frequencies your audience craves, all packed in a travel-friendly enclosure your back will appreciate. This subwoofer is a serious sonic upgrade designed to push your portable PA system to its absolute limit.
