Physicist Klaus Heinz and his son, Dr. Frederik Knop founded HEDD | Heinz Electrodynamic Designs in October 2015.  For the past 40 years, they have developed high-end loudspeakers that have become established constants in diverse fields: from music production processes, mastering studios to radio broadcasting, installation and finally home Hi-Fi.

Their designs are centred around the Air Motion Transformer technology, creating  surgically precise studio monitors that producers and sound engineers use as tools. Their most recent innovation, HEDDphone, is the world’s first full range Air Motion Transformer headphone.
