Kenwood LS-3000 (1975)
The Kenwood LS-3000 is a bookshelf speaker from 1975. In some markets it was sold under the TRIO brand, which was common for Kenwood's export models of the era. Documentation is thin. Nearly everything known about this model traces back to a single classified listing and a couple of forum mentions, so the record here is lean.
The available sources agree on the basics. It's a two-way design built around a 20 cm cone woofer with a crossover at 4 kHz. It's rated for 40W maximum input at 8 ohms, with a sensitivity of 91 dB/W/m and a stated frequency range of 40 Hz to 20 kHz. The cabinet measures 257 × 572 × 243 mm (W×H×D) and weighs 10 kg. Take that frequency response figure with the usual period caveat. It's likely the manufacturer's nominal rating, not a measured ±3 dB window.
Beyond those basics, almost nothing is recorded. There's no original price, no driver details beyond the woofer size, no cabinet construction notes and no owner reviews from the period. A Dutch forum post dates a pair to 1975, and a Moscow classifieds listing offered a pair at 36,200 rubles. That's the extent of the market trail. A Yahoo auction listing for a pair noted the TRIO branding, which fits with Kenwood's export naming conventions of the mid-1970s.
If you own a pair, you're holding a piece of Kenwood's early speaker history that simply didn't leave much of a paper trail. The specs suggest a modest, competent two-way bookshelf design typical of the era — nothing exotic, but solidly specified. That's about all the record supports.
