Gearank Recommendation

This appeared on our recommended list for Powered PA Speakers under $2000 from May 2021 until March 2022 when it was removed due to a price increase that made it ineligible for the list.


The QSC KLA12 is a a lightweight, powered line array speaker that works equally well as a single unit.

As part of a flown array, the KLA12's 1.75" HF driver gets directed by a specially designed waveform for excellent dispersion.

A full 90° x 90° array can be achieved with just 4 units.

For pole mounting, the built-in tilt direct aids positioning and aim.

A total of 5 units can be stacked and flown for maximum dispersion at larger venues.

Those that want a compact line array system have chosen the KLA12 for its modularity and mounting options with it being relatively easy to set up.

They synergize well with most subwoofer systems and have a clear, precise sound with great dispersion.

If you're looking for a compact line array for semi-permanent installations in venues, the QSC KLA12 is a smart choice.
