JBL C35

The JBL C35 is a compact two-way bass reflex loudspeaker. It uses a 200 mm woofer and a 25 mm dome tweeter, with the crossover at 3500 Hz. The load is a nominal 8 ohms, and power handling is rated at 25 watts. Frequency response is specified at 50-20000 Hz (±6 dB). It measures 280 × 430 × 230 mm (W×H×D) and weighs 6.0 kg.

Past those basics, the record on the C35 is thin. No production years, original price or market positioning have turned up in the available documentation. A single eBay listing for a used pair calls them vintage JBL bookshelf speakers in good working condition, which fits the compact dimensions.

The C35 name also shows up in period JBL advertising. HiFI-Stereo (1959, p.9) ran a JBL ad listing a "Model C-35 Enclosure" alongside a lowboy variant, the C-37. That suggests the C35 designation may have first referred to a speaker enclosure in JBL's component line. Whether that enclosure relates to the later C35 bookshelf speaker described above is not documented. The specifications from hifi-wiki.com are the only complete technical record found.
