Kenwood LS-770E
The Kenwood LS-770E is a two-way, two-speaker loudspeaker system made in Japan. It is rare. It shows up on the secondary market so seldom that one Polish seller called it "extremely rarely seen." Documentation is thin, and almost everything known about this speaker comes from a handful of classified listings rather than period reviews or service manuals.
The listings agree on the basics. It's a bass-reflex design with a rear port, built around a 20 cm mid-bass driver and a 25 mm soft fabric dome tweeter, crossed over at 2 kHz. The cabinet is solidly built. At 270 × 480 × 259 mm and 10 kg, it's a substantial bookshelf-or-standmount box. Rated sensitivity is 88 dB/W/m and impedance is 4 ohms. Power handling is listed at 70 W nominal / 110 W music. Frequency response is quoted at 45-20,000 Hz.
One German listing calls the LS-770E "aus der Vorserie" - from the pre-series - which suggests it came before later Kenwood LS models, though no explicit lineup hierarchy is documented. A period marketing note from Ters Audio claimed the design had "been around for quite a while" and was brought into the UK mainly to satisfy customers who wanted matching badges across their Kenwood systems. That's a candid admission that brand cohesion drove it as much as new engineering did.
A Polish owner's description says the sound leans toward strong, confident bass with good depth, a clear and balanced midrange that handles vocals naturally, and a bright but smooth treble without metallic edge. The same seller noted the cabinets "look significantly better in person." A Belgian listing simply called them "very solid speakers" in near-new condition with heavy enclosures.
No production years, original price, or detailed circuit information has surfaced. The LS-770E remains a genuine collector's find — a well-regarded but sparsely documented Kenwood two-way from the company's Japanese speaker era.
