JBL PR10

The JBL PR10 is a professional-series loudspeaker, and the documentation on it is essentially limited to a single manufacturer product page. No production years, original pricing, or third-party reviews have surfaced in the available record — what's known comes straight from JBL Professional's own specifications. A 1968 Audio magazine installation feature described a philosophy of making a maximum initial investment in top-quality components, acquiring them one by one as funds permit (Audio, February 1968, p.9).

The PR10 is a two-way design built around a 12-inch woofer with a whizzer cone and a 1-inch titanium compression driver, crossed over at 3.6 kHz. The woofer uses a dual voice coil, dual gap system, which is the notable engineering feature here. The cabinet disperses sound at 100° × 100°, and the speaker is rated for 250 watts RMS (500 watts program) at 8 ohms, with a sensitivity of 95 dB SPL (1W@1m) and a frequency range of 48 Hz to 18 kHz. It weighs 33 pounds and measures 22.1 × 14.6 × 11.0 inches.

JBL positioned the PR10 for performers, DJs, and sound rental companies — a working speaker rather than a hi-fi showpiece. Beyond that, the record is thin. No details on cabinet construction, input connectors, or crossover type are documented. It's a straightforward professional PA speaker whose specs tell most of the story that's available.
