JBL 4318

Documentation on the JBL 4318 is thin. It appears to have been a two-way bass-reflex studio monitor built for the Japanese market. audio-database.com describes it as a "Japanese class studio monitor," and the model number fits JBL's long-running 4300-series monitor naming convention. What the record shows is a compact monitor with an 8-inch (200 mm) cone woofer and a 1-inch (25 mm) horn/dome tweeter, crossed over at 2200 Hz. The cabinet measures 254 mm × 508 mm × 318 mm and weighs 13.5 kg.

The published specs are consistent across the reference sites that list it: 55 Hz to 40 kHz frequency response, 8-ohm impedance, and 150 W maximum input power. No production years, original price, or period reviews have surfaced. The only user report found is a brief Audiokarma forum mention from an owner who had been using a pair for over two years, paired with VTL amplifiers and Apogee Duetta Signatures. That says something about the company the speakers kept, if not much about the speakers themselves.

Surviving listings suggest current asking prices range from roughly $499 to $649 USD (one Canadian listing asked $1,950 CAD). None are dated, so treat those figures as loose indicators, not a firm market value.
