The QSC KLA181 is a powered 18-inch flying subwoofer built to deliver impactful, extended low end for line-array and standalone PA systems. A 1,000 W power module drives a vented 18-inch transducer, producing up to 135 dB SPL peak with response down to 33 Hz for tight, musical bass that stays controlled at high levels. Onboard DSP optimises voicing and protection, ensuring consistent performance and long-term reliability in demanding professional use.
Integration is fast and tidy with powerCON Input and Thru for mains linking, while multiple rigging options support flexible deployment. Fly KLA181 using M10 fittings or the KLA12AF array frame, or ground-stack with confidence. Black models include a threaded pole mount capable of supporting up to two KLA12 enclosures, enabling compact, scalable systems without separate stands.
From touring and live music to corporate events, houses of worship and fixed installations, the KLA181 provides clean, authoritative low-frequency reinforcement that scales effortlessly with your project. Choose it when you need powerful, controllable bass and straightforward rigging in a robust, professional package.
