Altec Lansing, Inc. is a U.S. audio electronics company founded in 1927. Their primary products are loudspeakers and associated audio electronics for professional, home, automotive and multimedia applications. Engineers at Western Electric, who later formed Altec Services Company, developed the technology for motion picture sound that was introduced in 1927, with the release of The Jazz Singer. Originally, Altec Services Company serviced the theater sound systems the company founders had helped develop. In 1941 the Altec Services Company purchased the nearly bankrupt Lansing Manufacturing Company and melded the two names, forming the Altec Lansing Corporation, and with the manufacturing capabilities of the former Lansing Manufacturing Company, they quickly expanded into manufacturing horn loudspeakers. In 1958 the Altec Lansing Corporation was purchased by James Ling who made it part of LTV Ling Altec. LTV spun off Altec which it loaded down with debt first. By 1974, the company was saddled with debt. It was reorganized under Chapter 11 as Altec Corporation and continued for 10 years. Altec filed a second bankruptcy. In 1984, Gulton Industries purchased the brand out of Chapter 11 bankruptcy. Gulton was acquired by Mark IV Audio.Since then, there has been a string of owners, purchased in 1986 by Sparkomatic, with the Pro equipment still made by Mark IV Audio, Mark IV sold out to Telex, who closed down the Pro division and folded its products into Electro-Voice. In 2005 Altec Lansing Technologies was acquired by Plantronics, 2009 bought by Prophet Equity, and has been owned since 2012 by the Infinity Group, a company which acquires struggling companies. Popular loudspeakers included the Altec Lansing Duplex 600-series coaxial loudspeaker, studio monitors from the 1940s to the 1980s, and the Altec "Voice of the Theatre" line of loudspeakers widely used in movie theaters, concert halls, and also in rock concerts from the 1960s to the 1990s, such as custom designs used at Woodstock Festival.
