Physicist Klaus Heinz and his son, Mastering Engineer / Musicologist Dr. Frederik Knop founded HEDD Audio in October 2015. As acoustic professional and music enthusiast, Heinz’ life oscillates between the worlds of physics and sound. For the past forty years, Klaus Heinz (founder of HEDD and ADAM Audio) has dedicated himself to developing loudspeakers that have become established constants in diverse fields: from music production to professional mastering and finally home HiFi, his loudspeakers can be found in a great variety of contexts.

Heinz’ loudspeaker designs have always stayed true to the same ideal of sonic excellence: they have, above all, aimed to produce complete accuracy and outstanding signal fidelity while being less concerned with tinging recording audio material with pleasing tonal colors. It comes, therefore, as no surprise that that HEDD R&D is fully committed to the idea of creating versatile and surgically precise studio monitors and HEDDphones® that producers, sound engineers, and high-end enthusiasts can enjoy.
