JBL S400WG (After 2005)
The JBL S400WG is a bookshelf speaker made for the Japanese market, built after 2005. Most of JBL's effort went into the cabinet: carefully selected cherry natural wood with a high-gloss coating. The company described the finish as time-consuming and labor-intensive, and said it gave a luxurious feel. This was a premium domestic-market variant, not a global release, so documentation outside Japan is thin.
Inside is a 2-way, 2-speaker bass-reflex system. The low end comes from a 20 cm paper-cone woofer with a pure pulp diaphragm, mounted on JBL's signature square (irregular quadrilateral) high-rigidity aluminum die-cast frame. Highs go to a horn-type tweeter with a 2.5 cm pure titanium diaphragm, and the horn itself is cast in rigid aluminum. JBL also added its proprietary directional control technology to cut unwanted reflections from walls and ceilings. The whole speaker is magnetically shielded, so it can sit near a TV. The enclosure is MDF, bass-reflex loaded.
Specs are respectable for the size: 50 Hz to 35 kHz frequency response, 6 ohm impedance, 88 dB/2.83V/m sensitivity, 100W maximum music input, and a 3 kHz crossover. Each speaker measures 237 x 374 x 259 mm (W x H x D) and weighs 9.0 kg. The original price is listed at ¥88,000 per unit, with a May 2005 sale record on file. A separate Japanese listing shows ¥176,000 tax-excluded, which likely represents a pair.
JBL offered matching accessories, all finished to match the wood gloss cabinet. The S400WG Stand ran ¥37,000 per piece and measures 270 x 558 x 330 mm. The universal MTC-U1 bracket (¥9,000) handles wall or ceiling mounting - and in the normal orientation it needs the optional MTC-S4 4" shaft (¥3,000). The record on this model is otherwise quiet: no production years beyond "after 2005," no owner reviews, and no driver model numbers have surfaced. A 2021 Russian listing asked 68,000 rubles, later dropped to around 52,000.
