Kenwood S-3 (1975–1977)

The Kenwood S-3 is a 2-way bass reflex speaker system produced from 1975 to 1977. Documentation is thin. No original brochure material or launch pricing has surfaced. The specs that do exist come from a German database and a single owner's blog, and they describe a serious, substantial floorstander from Kenwood's mid-1970s lineup. Kenwood was advertising its new top-of-the-line receivers in HiFI-Stereo (June 1974, p.58) around this era.

The cabinet houses a 300 mm cone woofer crossed over at 3,500 Hz to a horn-type tweeter. Frequency response is rated at 50-20,000 Hz, impedance at 8 ohms. Power handling is the one spec that varies between sources. One lists 55 W nominal / 80 W maximum, the other 60 watts. The exact figure is uncertain, but this was clearly a speaker meant for real amplifier power. Dimensions are 360 × 625 × 300 mm and it weighs 12.5 kg.

What little is known about real-world reception comes from a collector who acquired a pair as new old stock in Europe, where they were apparently hard to find. He paid $180 for the pair, which he called very reasonable. He described them as "beautiful and powerful-sounding," with impressive depth and a knack for handling rock and electronic music at high volumes. The same source calls them a "12-inch 3-way" in one breath, while the spec table says 2-way. That may mean the horn tweeter was perceived as covering two ranges, or the blog post wasn't carefully edited.

No service manual or marketing materials have surfaced, and period reviews are limited to Kenwood's broader product line. Details on crossover components, connector types, and common failure points remain undocumented. For a speaker of this era and construction, a recap and check of the crossover is the usual starting point for restoration, but that's general practice, not specific knowledge about this model.
