Lexicon is an American company that engineers, manufactures, and markets audio equipment as a brand of Harman International Industries (HII), with offices in Salt Lake City. The company was founded in 1971 and headquartered in Waltham, Massachusetts. It was acquired by HII in 1993.
Lexicon traces its history to the 1969 founding of American Data Sciences by MIT professor Dr. Francis F. Lee and engineer Chuck Bagnaschi, developers of digital audio devices for medical heart monitoring.
The company is widely known for the design and development of the multi-speaker audio system for the Rolls-Royce Phantom — in addition to the Hyundai Genesis, Hyundai Equus, and the Kia K900.
