Description

QSC KLA 181 is a line array subwoofer with a 1000 Watt Class D amplifier that features an 18-inch cone and has a frequency range that goes down to 33Hz, it has a peak SPL of 135 dB and an integrated DSP that further improves and protects its performance. On the rear panel, we find 1 XLR input for line signal and 1 XLR output, 2 powerCON connectors for input and output power. On the back, there is also 1 potentiometer to adjust the input signal level, 1 potentiometer to invert the subwoofer's polarity and 1 to select DEEP mode.

 The cabinet made of birch plywood is light yet durable. Suspension mounting is possible via the M10 inserts or the KLA 12AF array frame. Additionally, a threaded pole mount is integrated (black models only), allowing for the installation of up to two KLA12s.
