The story
MTX audio was called Matrecs in 1979. The MTX name came in when Loyd Ivey, then owner of his own company American Acoustic Labs, bought out the Matrecs name in 1979 and changed it to MTX under Ivey’s parent company Mitek. In 1991, MTX Audio acquired Soundcraftsmen, a defunct audio equipment manufacturer which was located in Santa Ana, California, and was called MTX Soundcraftsmen until 1999.
In 1984 MTX created the first mobile audio enclosure.
