The QSC KLA12 loudspeaker features a very efficient 1,000 watt amp module (500 watts to the 1.75″ HF compression driver and 500 watts to the 12″ LF woofer) . As part of the QSC K Series Family, the KLA12 utilizes award-winning K Series technology like built-in DSP processing with QSC’s DEEP™ algorithm for extended bass response and GardRail™ providing amp protection and preventing unnatural clipping. The KLA12 can be used in conjunction with the QSC KLA181 subwoofer, either as a satellite speaker mounted on a pole over the KLA181, or strapped together with the KLA181 as a single flown system.

The speaker is expressly designed for use in fixed arcuate line arrays, and has a 12:1 design factor with a 90 x 18° coverage pattern, allowing up to 5 units to be configured for 90 x 90° coverage. Most other systems require 6 units for the same coverage pattern. The KLA12’s SOLO (Single-Operator Logistics) Rigging System allows you to easily assemble and disassemble the line array in a short amount of time without special tools or external hardware.

Ar-Q (Arcuate Equalization) processing enables you to quickly tune the array, making appropriate adjustments based on the number of boxes in your array. By simply using a dial, you can choose the total number of boxes for a balanced and accurate tonal curve. Proprietary Intrinsic Correction technology adjusts the time, frequency, and amplitude response for a flat bandpass target.

Up to 2 loudspeakers can be mounted on a stand or over a sub for a ground stack, thanks to a threaded Tilt-Direct 35mm pole socket. The socket also allows you to aim the speaker 9° downward for the best audience coverage. M10 fittings in the top of the enclosure allow up to 5 units to be flown in a suspended rig. An optional array frame is also available separately for additional mounting options.
