JBL S1500C

The JBL S1500C is a center/satellite speaker system, originally priced at ¥95,000 per unit. It was designed to pair with JBL's S3500 and S2500 models in a home theater setup. Documentation on this model is thin. Nearly all technical facts trace back to a single Japanese spec database. What's recorded shows a substantial, well-built center channel.

It's a 2-way, 3-speaker bass reflex design with magnetic shielding. It uses two 16.5 cm pulp-cone woofers with JBL's traditional corrugated-rib diaphragm construction, plus a horn-loaded tweeter with a 2.5 cm pure titanium diaphragm on a Bi-Radial horn. The horn/driver section can be rotated 90 degrees, so the cabinet works horizontally as a center speaker or vertically as a satellite. The enclosure is finished in cherry natural wood veneer.

Rated specs are a frequency response of 55 Hz–50 kHz (±0 dB), output sound pressure level of 89 dB/2.83V/m, 6 Ω impedance, and 75W maximum allowable input, with the crossover set at 3 kHz. It measures 682 × 251 × 200 mm (W×H×D, excluding horn projection) and weighs 15.4 kg.

Beyond those figures, the record goes quiet. No production years, no period reviews, and no owner impressions have surfaced. A single ended Yahoo! Japan Auctions listing (May 2026) sold a used example from Gunma Prefecture, described as having fine scratches on the wood grain, with operation unconfirmed. The final price was 3,900 yen. The Japanese price-comparison site kakaku.com lists the S1500C but notes no current price information is registered.
