Kenwood LS-X9 (c. 1976–1977)
The Kenwood LS-X9 was the middle child of Kenwood's late-1970s LS-X speaker family. It sat between the 3-way LS-X7 and the larger LS-X11. It's a floor-standing 4-way bass-reflex design that weighs 39.5kg, so nobody moves it casually.
The driver lineup is a 30cm cone woofer, a 12cm cone midrange and a 6cm cone tweeter. The 4-way arrangement suggests an additional 6cm midrange driver handling the upper frequencies. Crossover points are 300Hz, 2.5kHz and 7kHz. Kenwood rated the LS-X9 at 130W maximum input, 8 ohms impedance, with a frequency response of 25Hz - 25kHz and sensitivity of 88 dB/W/m. The cabinet measures 406 × 855 × 381mm (W×H×D).
The original price was approximately ¥98,000 in the Japanese domestic market. The Vintage Knob dates the model to roughly 1976 - 1977, though exact production years aren't firmly documented. HiFI-Stereo (May 1993, p.18) covered Kenwood's new products of that era, but by then the LS-X9 was long out of production. The company had moved on to combi-players and home theater gear.
Documentation on the LS-X9 is thin beyond its basic specifications. No owner reviews, market values or common-failure information surfaced in the research, and the exact driver configuration of the 4-way system isn't fully clarified in available sources. It was a high-mass speaker from the era when Japanese manufacturers were pushing hard into the high-end loudspeaker market, and it shared its family lineage with the smaller LS-X7 and the flagship LS-X11.
