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.
