Kenwood LS-77 (1988)
Documentation on the Kenwood LS-77 is thin, even by vintage speaker standards. What the record shows: it was a speaker system sold under both the Kenwood and Trio names (Trio being Kenwood's domestic-market brand), and it dates from 1988.
The driver layout is the interesting part. Sources describe it as a "same axis horn type" - a coaxial design, with a horn-loaded tweeter mounted on the same axis as the woofer - paired with a passive radiator. That's an unusual layout for Kenwood, which mostly stuck to conventional multi-driver baffles in this era. The passive radiator approach was more common in Japanese domestic-market designs of the late '80s, where small listening rooms made compact bass loading attractive.
Owner chatter is scarce but mildly positive. One French forum post from the period calls the LS-77 "tres sympa" (quite nice) and groups it with contemporaries like the Bose 201 Series III, JBL TLX300, and Chario Syntar MkII. A Japanese auction listing from 2023 shows a pair of LS-77s selling for ¥1,621 (roughly $12 at the time), described as used but operational.
That's about all that's documented. No power handling, impedance, frequency response, dimensions, or weight figures have surfaced. No original price, no detailed reviews, no known failure points. If you own a pair, you're holding one of the more obscure corners of late-'80s Kenwood — a coaxial curiosity from a brand better remembered for its amplifiers and receivers than its speakers.
