The QSC KLA12 Active Line Array Speaker is a revolutionary loudspeaker that redefines what's possible from a portable line array. Delivering an astounding combined 1000W of power, the KLA12 packs the punch of a traditional line array system into a streamlined package. Equipped with a specialized 12" woofer and 1.75" compression driver, this speaker offers pristine sound with a frequency range of 44Hz to 20kHz. The built-in 500W x 500W power module powers up to 5 units, allowing you to daisy chain multiple KLA12s together for expansive coverage.

SOLO Rigging Provides Effortless Setup

The KLA12 features QSC's innovative SOLO Rigging System, which allows a single operator to quickly and easily set up or take down the line array without any tools or additional hardware. The integrated rigging hardware and angled cabinet design enable you to assemble a vertical line array of up to 5 units, providing 90-degree vertical coverage and eliminating the need for additional speakers.

Ar-Q Tuning Optimizes the Array

QSC's Ar-Q Frequency Optimization lets you perfectly tune the line array with the turn of a dial. Simply select the number of units in your array, and Ar-Q will automatically adjust the EQ to optimize the frequency response for even coverage and balanced sound across the listening area.

Roadworthy Design Withstands the Rigors of Live Performance

The KLA12 is built to handle the demands of touring and live events. Its rugged ABS enclosure is highly durable yet lightweight, and the included carrying handles make transporting and setting up the 55 lb speaker a breeze. PowerCon input and thru connections provide flexible wiring options, while the pole mount socket allows you to elevate the speaker on a tripod stand for optimal coverage.

Unparalleled Power and Control

With 500W of power for the woofer and 500W for the high frequency driver, the KLA12 packs 1000W of total power in a single unit. The built-in DSP and active crossover network provide precise control over the frequency response. Features like GuardRail circuitry protection, Auto Standby mode, and balanced XLR inputs give you maximum control and flexibility.
