The white JBL Professional PD5122 is a passive, high-power, low-frequency module designed to be used with mid/high only or full-range modules, such as the PD5000, PD6000, and PD700 series loudspeaker systems. The PD5122 is principally intended to be used in conjunction with the PD5322 full-range system to construct arrays with extended low-frequency pattern control.

The enclosure is made with exterior-grade birch plywood and finished with a white DuraFlex finish. The PD5122 requires 4800W of output to power the dual 12″ VGC drivers, which provide a frequency response of 49 to 300 Hz with a peak SPL of 134 dB.
