Throughout four decades, the words “world’s first” have been closely associated with MK Professional subwoofer design and development. We introduced the world’s first integrated satellite/subwoofer system, David & Goliath, in 1975, the world’s first self-powered subwoofer, the Volkswoofer, in 1977 and the world’s first Home THX loudspeaker system, featuring the world’s first powered THX subwoofer in 1992. The list of MK innovations goes on and on.
