JBL 4206
The JBL 4206 is a passive, two-way bookshelf speaker with a bass-reflex enclosure — a compact near-field monitor from JBL's professional-leaning 4200 family. It pairs a 200 mm (8″) woofer with a 19 mm (¾″) dome tweeter, crossing over at 3 kHz. Rated sensitivity is 89 dB, impedance 8 ohms, and power handling 10–150 W. Frequency response is specified at 55 Hz–20 kHz. Two dimension sets appear across sources: 253 × 419 × 258 mm (hifi-wiki.com) and 9-7/8″ W × 16-1/2″ H × 10-1/8″ D (Vintage JBL). The cabinet weighs 7.8 kg. Connection is via 5-way binding posts.
One source identifies the 4206 as the home-audio version of the JBL Control 5 Plus studio monitor, with the same drivers and crossover and only the cabinet cosmetics differing. That relationship appears in a single source, so hold it loosely. The review also reported that both models' internal magnetic shielding caused no picture distortion when placed beside video monitors (Mix Magazine, May 1992, p.75).
Beyond that, the record is thin. No production years, original price, or crossover component details are documented. The driver materials (polypropylene-coated cone, titanium-laminate dome) come from a single source. No owner impressions or long-term reliability notes have surfaced in the research.
