JBL 4312 BMKII (1999)

A three-way bookshelf speaker system with bass reflex design, released around 1999.

Overview

The JBL 4312 BMKII is a compact, three-way speaker system designed for high-fidelity audio monitoring and home use. Manufactured by JBL, it features a bass reflex enclosure and is configured as a bookshelf-type speaker. The system uses three dedicated drivers: a 30 cm cone woofer, a 12.5 cm midrange, and a 2.5 cm dome tweeter. It was sold in Japan for ¥78,000 per unit around 1999. One known used purchase occurred in the early 1990s for $75, though that reflects a secondhand transaction unrelated to the original MSRP.
