Kenwood KX-660HX (c. 1988)
Little is documented about the Kenwood KX-660HX beyond a single equipment profile in Audio magazine. It was a moderately priced cassette deck, reviewed in April 1988, and the reviewer genuinely liked it. The manufacturer's specs in that profile (Audio, April 1988, p.82) put frequency response at 20 Hz - 16 kHz with Type I tape, extending to 17 kHz with Type II and 18 kHz with Type IV. The measured -20 dB responses were commended as very flat across all three tape types over nearly the entire band (Audio, April 1988, p.84). The same issue listed Kenwood's U.S. office at 2201 East Dominguez Street, Long Beach, California.
The review highlighted the deck's Zero Stop, Index Scan and Blank Search functions. Blank Search was the reviewer's personal favorite. His verdict was that for its moderate price the Kenwood performed very well in most respects, and its many features offered real benefits (Audio, April 1988, p.86). Recordings sounded quite good, though on at least one tape the reviewer backed the record level off a couple of decibels from his initial setting. Later tape-type notes in Audio (March 1990, p.66) observed that Type IV formulations delivered higher 125 Hz MOL and a slightly better 0 dB response.
That period coverage is all the solid documentation there is. No service manual, brochure, or production-date records have surfaced in the archive, so collectors working on one of these are largely on their own.
