KLH is an audio company founded in 1957 as KLH Research and Development Corporation in Cambridge, Massachusetts, United States, by Henry Kloss, Malcolm S. Low, and Josef Anton Hofmann originally to produce loudspeakers. KLH had sales of $17 million, employed over 500 people and sold over 30,000 speakers a year before it was sold to Singer Corp. in 1964. Later it was bought by Electro Audio Dynamics Inc. and moved to California in 1980.
KLH was then acquired by Kyocera Ltd, a Japanese conglomerate, and production was shifted overseas. Kyocera decided to stop manufacturing audio products in 1989, and sought a buyer for the KLH brand.
The company was formally known as KLH Audio Systems and for a while located in Santa Ynez, California. It was also known as Wald Sound and Verit Industries.
Later down the line, David P. Kelley (long time Klipsch and VOXX Executive) bought KLH Audio Systems and renamed the company to KLH Audio. The headquarters is now located in Noblesville, Indiana. Today the company makes premium high-end speakers.
