JBL 4304H
Documentation on the JBL 4304H is thin. What exists comes mostly from Japanese sales and buyout listings, not period reviews. It appears to have been a compact 2-way monitor sold in the Japanese market around 2005 - one unit was recorded selling for ¥53,000 in January of that year.
The spec sheet is clear enough. It's a 2-way, 3-speaker bass-reflex bookshelf design with two 13.3 cm pulp-cone woofers and a horn-loaded tweeter using a 2.5 cm pure titanium compression driver. Dual woofers with a horn tweeter is an unusual combination for a small monitor. JBL positioned it as a flexible option for both stereo and multi-channel systems, specifically as a center or surround speaker alongside larger main speakers that used compression drivers and horns. The compact size and high output were said to allow placement behind an acoustically transparent screen.
The woofers use accordion-pleated edges and aluminum die-cast frames. The cabinet is high-strength MDF with a black ash finish. It's magnetically shielded, which makes sense for home theater use near a CRT television. Wall and ceiling brackets were offered separately. Frequency response is rated at 60 Hz to 35 kHz, impedance 6 ohms, sensitivity 91 dB/2.83V/m, crossover at 3 kHz, and it handles 150W of music program material. It weighs 7.7 kg and measures 345 × 300 × 194 mm (W × H × D).
The one bit of real-world commentary comes from a Japanese buyout shop, which noted the previous owner had been using it for AV surround sound and was upgrading to a more expensive model. A used example from another dealer was described as having few scratches and clean condition after three years of ownership. That's about all there is. There are no production years, no detailed reviews, and nothing on how it fit into JBL's broader monitor lineup.
