KLH Model Nineteen (1958)
The KLH Model Nineteen is a loudspeaker system from 1958. Per the period record at radiomuseum.org, it ranks among the most successful speakers KLH ever produced. The same source notes that its basic design carried over into several later KLH systems. It was the successor to the KLH Model Ten, though little else about that predecessor is documented beyond its name.
The spec sheet is short but concrete. The Nineteen handles 14 watts, covers 45-13,500 cps, and presents an 8-ohm load. It weighs 28 lb and measures 20 x 12 x 9.6 inches (W×H×D as listed, though the order isn't confirmed). Driver count, crossover details and enclosure type are not recorded in the available documentation.
KLH's own advertising in the mid-1960s pushed the Nineteen as a "terrific thing" for $299.95, with effective controls that could tailor the sound to anything from a one-room shack to a grand ballroom - and noted that the tuner in the Model 19 was essentially the same as in another KLH design. HiFI-Stereo (September 1965, p.28) carried that campaign, as did High Fidelity (September 1965, p.26).
Beyond those fragments, the record is thin. No original price from 1958, no driver sizes, no sensitivity figure, no enclosure type and no production end year have surfaced.
