KLH 35 (1965)
The KLH Model 35 is a floor-standing, two-way speaker system introduced in 1965. It was priced at $57.50 each. KLH's own advertising around this period was already positioning the company's speakers as exceptional values in their price class. The 35 was aimed at listeners who wanted an honest, uncolored sound. The original 1965 ad copy called it "an honest speaker with honest sound," meant for people who wanted to hear exactly what their amplifiers and pre-amplifiers had to offer.
The Model 35 paired a 10-inch direct-radiating woofer with a 4-inch direct-radiating mid-high frequency cone driver, crossing over at 800 cps (cycles per second, the era's term for Hz). Advertised frequency response was 38 to 20,000 cps, with an 8-ohm impedance. The cabinet measured 15 inches wide, 31½ inches high and 12 inches deep, and weighed 45 pounds. KLH specified that the 35 was designed for amplifiers producing 15 to 30 watts of power.
The enclosure type is a muddle. The 1965 ad describes a "bass reflex type cabinet with ducted port," while the same source page that preserves that ad also describes the 35 as using both "acoustic suspension design" and "transmission line" loading. Those are mutually exclusive approaches, and the contradiction hasn't been resolved. The ducted-port description comes straight from the period advertising copy, so it's the most credible claim. Treat the enclosure type as an open question until a service manual or a hands-on inspection settles it.
The 1965 ad copy also claimed the 35's highs were "clean and open," the mid-range "natural and uncolored," and the bass "full-bodied and well-controlled," and that it reproduced realistic sound with modest amplifier power. That's manufacturer marketing, of course, but it fits how KLH positioned its speakers in this period: competent, affordable and honest rather than flashy.
Beyond that, the record is thin. No production end year, no sensitivity rating, no crossover component details, no finish options, and no independent period review of the Model 35 has surfaced in the research. The Radio Museum database lists it as a speaker, but no specs from that entry were extracted. The cabinet dimensions and driver complement above should help an owner confirm what they have, and pulling the grille would be a good start on the enclosure question. Contemporary KLH advertising in High-Fidelity (November 1970, p.91) promoted the company's speakers as exceptional values in their price class.
