Kenwood LS-770A Rare HiFi Loudspeakers

🎶 Kenwood LS-770A HiFi Loudspeakers — Vintage Japanese Audio Classic

The Kenwood LS-770A (often referenced as LS-770-series: LS-770A / LS-770) is a vintage Japanese-made HiFi loudspeaker system, representative of Kenwood’s high-fidelity ambitions of the 1980s. Though they’re now considered “retro,” these speakers still have character — particularly for lovers of dynamic, warm, and somewhat raw vintage sound.

Special design / engineering notes:
The woofer uses a “double voice-coil” design, which reportedly allows better control and power handling — helping the woofer avoid “breakdown” under heavy load and improving low-frequency performance.

Some versions allow level controls on mid/high frequencies — enabling tuning of tonal balance depending on room or listener preference.
