JBL 2365A

Name: JBL 2365A
Brand: JBL

The JBL 2365A is a two-way, bi-radial horn-loaded loudspeaker system from JBL's professional 2000-series, made for theatrical and performance sound reinforcement. It was the least expensive of the four bi-radial horn models JBL offered. It was built around JBL engineer John Eargle's Bi-Radial® horn geometry - a fiberglass horn throat and mouth that gives the system its boxy, 3½-foot profile.

The driver complement is a 2202H 12-inch woofer and a 2445J compression driver. The 2445J loads into the large bi-radial horn, which accounts for the system's 105 dB sensitivity (1W @ 1m). The 2365A was designed to be used with the JBL 2312 crossover and, for extended top-end, the JBL 2405 UHF driver. Neither is built in, so this is a component in a larger system, not a self-contained speaker. Recommended crossover point is 500 Hz or higher.

Surviving documentation is thin. No production years, original pricing or period reviews have surfaced in the archive. What the record does show is a professional-grade horn system with serious output and a clear intended role in cinema and performance venues. The specs that are documented are consistent across the manufacturer's spec sheet and the trade press that covered it.

Sound and Communication (January 1988, p.33) listed the 2365A among professional sound reinforcement offerings of the period. That places it in the installed-sound market, not consumer hi-fi.
