JBL PR15C

Little is documented about the JBL PR15C. The model designation is the first obstacle. The available research contains no page explicitly about a "PR15C," and the only related speaker found is the JBL PRX415M, a 15-inch two-way powered speaker. The record doesn't establish whether the PR15C is the same product under a different name, a variant, or something else entirely. What follows is what is known about the PRX415M, which may or may not be the model this page is meant to cover.

The PRX415M is a powered speaker — a 15-inch woofer paired with a 1.5-inch compression driver, driven by a 500-watt Class-D amplifier in a bi-amplified configuration. The internal amp is split: one Class-D module for the woofer, another for the high-frequency driver. Digital signal processing handles the crossover, EQ, and limiting. Frequency response is rated at 60Hz–20kHz (-10dB) and 75Hz–20kHz (±3dB). Inputs are XLR and 1/4-inch. The cabinet is plywood, in a multi-angle trapezoid shape, with a dual-angle pole mount socket. It weighs 48 lbs.

Audio (April 1983, p.82) ran a classified ad in the same era mentioning other gear, but no period review of this speaker has surfaced in the available documentation.
