KLH Audio is an American audio electronics company based in Noblesville, Indiana.^[2] Originally founded in 1957 as KLH Research and Development Corporation in Cambridge, Massachusetts, the company takes its name from the initials of its founders: Henry Kloss, Malcolm S. Low, and Josef Anton Hofmann.

History[edit]

The original aim of the company was to design and produce loudspeakers in speaker enclosures.^[3] KLH had sales of $17 million, employed over 500 people and sold over 30,000 speakers a year before it was sold to Singer Corporation in 1964.^[4] In 1970, KLH became a wholly-owned subsidiary of Electro Audio Dynamics (EAD) of Great Neck, New York.^[4] EAD moved KLH's headquarters to Canoga Park, Los Angeles, in 1980.^[4]

Japanese conglomerate Kyocera acquired KLH in 1982,^[5] and production was shifted overseas. Kyocera later decided to stop manufacturing audio products, and sought a buyer for the KLH brand. In 1989, KLH was acquired by Wald Sound of Sun Valley, Los Angeles.^[5]

In 2003, Sony filed a lawsuit against KLH (then Lavcon, Inc., trading as KLH Audio Systems) asserting copyright infringement of a Sony home theater system.^[6]

In January 2017, Kelley Global Brands bought the company and renamed it KLH Audio.^[7][8] The company makes premium high-end speakers.
