This QSC KLA line array bundle is a compact, high-performance sound system designed for professional live events, touring, and rental applications. The package includes four QSC KLA12 line array speakers, each powered by dual 500 W amplifiers and housed in a lightweight ABS enclosure for easy transport and setup. Featuring QSC’s Ar-Q frequency optimisation, the system automatically adjusts performance based on the number of arrayed elements, supporting up to five KLA12 modules and two KLA181 subwoofers per frame. With a 90° x 18° coverage pattern, integrated tool-free Solo rigging system, Power Twist connectivity, and pole-mount capability, the KLA12 delivers consistent, high-quality sound with fast deployment.

Low-frequency reinforcement is provided by two QSC KLA181 active subwoofers, each equipped with an 18″ driver and a 1000 W amplifier module, producing tight, powerful bass with a peak SPL of 135 dB. Power Twist input and output connections ensure clean, secure power distribution across the system, while the rugged design supports both ground-stacked and flown configurations.

The bundle is completed with Cordial professional XLR microphone and patch cables for reliable signal transmission, K&M M20 distance rods for secure sub-to-top mounting, and Varytec Power Twist link cables for dependable power connections. Finished in black, this turnkey QSC KLA system is ideal for live sound, corporate events, houses of worship, and rental setups requiring scalable line array performance with quick and efficient setup.
