JBL 2310

Little is documented about the JBL 2310. What the record shows is a 2-way crossover network, a component intended to split an amplified signal between a woofer and a tweeter in a two-way loudspeaker system. Beyond its basic specifications, almost nothing else has survived in the historical record.

The known specs, drawn from a pair of dealer listings that appear to share a common upstream source:

No production years, original price, or weight have been found. No design or construction details — crossover topology, slope, component quality — are documented. There are no period reviews, no owner commentary, and no confirmed relationship to other JBL models of the era. The two sources that list these specifications are verbatim identical, so they do not independently corroborate one another. This is a genuine gap in the record: the JBL 2310 clearly existed and was sold, but the paper trail around it is remarkably thin.
