Martin Audio is a British professional loudspeaker manufacturer founded in 1971 by Dave Martin, one of the early pioneers of professional touring sound. Headquartered in High Wycombe, Buckinghamshire, England, the company built its reputation providing PA systems for supergroups of the 1970s, including Pink Floyd, The Who, and Supertramp. Dave Martin is credited with developing the folded horn-loaded bass cabinet principle and the MH212 'Philishave' midrange speaker before his passing in 1992.
