It has a peak sound pressure level of 135 dB and includes an integrated DSP that further enhances and protects its performance. On the back, there is 1 XLR input for line signals and 1 XLR output, along with 2 powerCON connectors for input and output power. Additionally, there is 1 potentiometer for adjusting the input signal level, 1 potentiometer for inverting the subwoofer phase, and 1 potentiometer for selecting the DEEP mode.

The birch plywood enclosure is lightweight yet sturdy. Suspension is facilitated by M10 inserts or the KLA 12AF array frame. There is also an integrated (available only on black models) threaded rod mount that allows for the installation of up to two KLA12 units.
