Kenwood KL-777DX (1983)
A floor-standing loudspeaker system released by Kenwood in 1983, notable for an unusually wide frequency response range.
Overview
The Kenwood KL-777DX is a stereo loudspeaker system introduced in 1983. It measures 16.3 x 27.8 x 10.75 inches and weighs 36 pounds, so the cabinet is a big one. The claimed frequency response runs from 7 Hz to 50 kHz, far wider than typical speakers of the era. That reaches well below and well above the audible range. Total harmonic distortion is rated at 0.03%, though the test conditions and frequency range for that figure are not documented in available sources.
