KLH Model 354 (circa 1977)
Little is documented about the KLH Model 354. The record shows a speaker system that appeared in the January 1977 issue of HiFi-Stereo (formerly HiFi/Stereo Review). The magazine reviewed it alongside the JVC 1R-SR00 AM/FM Stereo Receiver, the Marantz Model 1250 integrated amplifier, and the Micro Seiki DDX-1000 turntable. It published tone-burst response photos of the 354 at 100, 2,000, and 10,000 Hz. The speaker showed no signs of erratic response or sustained ringing when driven with 10 watts into an 8-ohm load, with the input adjusted to maintain constant acoustic output.
Beyond that review, almost nothing survives in the public record. No brochure, service manual, or specification sheet has turned up in the usual archival sources.
