The QSC KLA Series redefines the line array system! With these powered speakers serving as the foundation of your audio arsenal, you won't have to worry about the high levels of maintenance that usually accompany more complicated line arrays. There are two models in the KLA lineup - the 12-inch, 2-way loudspeaker (KLA12) and the 18-inch subwoofer (KLA181) - and their power amp modules allow for up to any combination of five models to be driven off a single 15 amp, 120 volt electrical circuit. KLA Speakers are easy to use and can be utilized quickly using QSC's simple ‘Lift, Click, and Play' approach - you have the freedom to deploy these on the ground or fly them using the QSC AF12 Array Frame. QSC KLA Speakers are just the thing for live touring rigs, performance halls, music festivals, houses of worship, and other venues where a line array is preferred.
