Kenwood SW-X1 (1987)
The Kenwood SW-X1 is a subwoofer speaker from 1987. It survives in the historical record mostly through a single German vintage audio database entry. That entry lists a 250 mm woofer rated at 120 W peak music output, with a frequency response of 75-2000 Hz and an adjustable crossover spanning 75-200 Hz. Impedance is 8 ohms. It weighed 13.5 kg and measured 397 × 380 × 370 mm (H×W×D). The original German market price was 599.00 DM. The period press covered speakers with similar specifications, such as sealed designs with 6.5-inch woofers and 100 W power handling HiFi-Stereo (1997, p.112).
Beyond those basics, documentation is thin. The fact sheet gives no details on whether the SW-X1 was passive or powered, its cabinet construction (ported vs. sealed), finish options, or input connections. The unit does appear on the used market occasionally - one recent listing on Reverb offered it at $200 in "Very Good" condition, plus shipping.
