QSC’s KLA Series brings the power and sophistication of a line array system into an easy-to-use product significantly redefining the line array product category. Sam Ash Direct has the guaranteed lowest price and fast free, shipping.

The QSC KLA12 12-inch, 2-way loudspeaker features a highly efficient built-in 500-watt by 500-watt power amp module. This efficient design enables up to five KLA models (any combination of KLA12 and KLA181) to be driven off of a single 15 amp, 120-volt electrical circuit.

Housed in a rugged ABS enclosure that results in both lightweight and long-term durability, the KLA12 features a 12-inch low frequency transducer coupled with a 1.75-inch compression driver. Designed to be used exclusively as a fixed arcuate line array, each KLA12 is set at a 90° horizontal by 18° vertical splay angle, allowing 90° vertical coverage arrays to be configured using only five boxes (most other solutions require six).

QSC KLA12 enclosures also feature the Tilt-Direct™ 35mm pole socket allowing the loudspeaker to be aimed downward 9° for the best audience coverage.

KLA's unique self-contained SOLO™ (Single-Operator Logistics) Rigging System enables users to quickly assemble (and disassemble) the line array in a fraction of the time without the need for special tools or external hardware.

The KLA12 Ar-Q™ (Arcuate Equalization) processing enables users to quickly tune the array, making appropriate frequency compensation adjustments based on the number of boxes. With the click of a dial, the user can select the total number of boxes deployed in the array resulting in an evenly balanced and accurate tonal curve. QSC's proprietary Intrinsic Correction™, first introduced with the WideLine™ Series, actively adjusts time, frequency and amplitude response to achieve a maximally flat bandpass target.
