MTX Audio is an American consumer audio company that manufactures sound equipment for many applications, including car audio, home audio, marine audio and live sound products. They are best known for their car audio products and they specialize in subwoofers and subwoofer amplifiers. MTX Audio is a brand name owned by the Mitek Corporation. MTX Audio, as well as Kicker and JL Audio, is known as one of the pioneers of the car audio industry. MTX Audio's parent company, Mitek Corporation, patented the square speaker design, which has more surface area for its nominal diameter as it is not measured diagonally. The patent was filed and published in 2007. The MTX Jackhammer 24 is a 24 inch square subwoofer and one of the largest available on the consumer market.

MTX Audio was founded in 1979 by 26-year-old Loyd Ivey in Winslow, Illinois, when Ivey turned his hobby of building speakers into a business. 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.
