JBL PR15

Little is documented about the JBL PR15, and what survives is fragmentary. The one solid reference point is a 1969 issue of Audio (1969, p.74). It lists the PR15 as a passive radiator priced at $237.00, noted as combinable with the "Olympus" system. The same listing puts the PR15 next to the LE14A 14-inch low-frequency driver, which was offered for use in cabinets as small as 1.5 cubic feet.

Beyond that listing, almost nothing is recorded. The PR15 appears to have been a passive radiator - a non-powered driver used to augment bass output in a sealed enclosure - rather than a complete speaker system. The "PR" designation in JBL's naming of the era supports this reading. So does the fact that it shows up in a speakers-and-cabinets price list rather than among complete systems.

The $237.00 price suggests a substantial component, and the Olympus association indicates it was meant for JBL's higher-end offerings of the period. No specifications have surfaced in the available record, though. No dimensions, no frequency response, no impedance, no power handling.

Known facts:

- Listed as a passive radiator, $237.00

- Could be combined with the "Olympus" system

- Appeared alongside the LE14A woofer in period pricing
