Description

The KLA Series brings the power and sophistication of a line-array system into an easy-to-use product. With its simple Lift, Click and Play approach, KLA deploys in a fraction of the time required by comparable line-array products. This fixed arcuate, active line-array system is ideal for a wide range of portable and permanently installed applications ranging from live entertainment to houses of worship or other venues where a line-array system is desired.

The KLA Series is comprised of two models: the KLA12 12-inch, 2-way loudspeaker and the KLA181 18-inch subwoofer.
