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.
Not only are HEDD’s loudspeakers produced in Berlin, they also feature an unprecedented level of digital signal optimization (HEDD Lineariser®), improved diaphragm materials as well as ultra-efficient amplifiers. Last but not least, brand-HEDD Audio takes another technological step in the development of the Air Motion Transformer.
30 years ago HEDD founder and CTO Klaus Heinz designed the first compact and marketable AMT tweeter based on American-German Physicist Oskar Heil’s original Air Motion Transformer invention. Since then, Heinz has increased its sonic quality in several fundamental revisions for his loudspeaker tweeter designs at ADAM Audio and HEDD.
In 2019 Heinz has started developing a full range Air Motion Transformer to break new grounds for this superior transducer principle. In order to reproduce the complete audible frequency band (and beyond), the HEDDphone® incorporates VVT® technology (Variable Velocity Transform). It introduces a new, variable diaphragm geometry that expands the AMT principle to a linear full range (10Hz–40kHz) headphone transducer.
Years ago, Heinz revolutionized the professional world of audio production by introducing his first Air Motion Transformer. Today, AMT systems are used wherever an extremely precise and vivid reproduction of high frequency material is called for.
