HEDD Type 07 Studio Monitor Pair  From HEDD

Innovative "Air Motion Transformer" Tweeter design and flexible I/O cpabilities make these monitors perfect for any listening environment. 


Manufacturer's Description from HEDD

Our Type 07 studio monitor could be described as a classic nearfield monitor speaker, although that would not nearly do justice to its versatility and powerful sound. On first glance, this model’s standard size and classic setup with a 7” woofer and a HEDD Air Motion Transformer do not leave much room for additional technological advances. Yet the careful adjustment of its various components, particularly the way in which casing, amplifier, and diaphragm interconnect, creates a degree of sonic stability, strength, spatiality, and transparency that amazed us from the very first stages of this model’s development on. With its 2×100 Watt amps and its extremely well balanced frequency response, the Type 07 monitor sounds much bigger and more mature than its moderate size and sleek design make it appear. It is precisely for this reason that there is hardly a field of audio production, which the Type 07 is not ideally suited for: its clever design makes it an especially good player in broadcasting contexts as well as in recording and mix-down studios.


Our Type 07 studio monitor comes, like all models of our Series ONE, with XLR and RCA connections. In addition, it also features an empty slot that allows for a wider range of digital functionality. At the moment, we offer HEDD Bridge modules that can handle Dante (Audio-over-IP) transport.


About Manufacturer

Physicist Klaus Heinz and his son, Mastering Engineer / Musicologist Dr. Frederik Knop founded HEDD | Heinz Electrodynamic Designs in October 2015. As acoustic professional and music enthusiast, Heinz’ life oscillates between the worlds of physics and sound. He is the founder of several renowned companies, among them loudspeaker manufacturer ADAM Audio, as whose Managing Director and Head of Research & Development he served for many years. For the past forty years, Klaus Heinz has dedicated himself to developing high-end loudspeakers that have become established constants in diverse fields: from music production processes in professional recording and mastering studios to radio broadcasting, installation and finally home HiFi, his loudspeakers can be found in a great variety of contexts. Despite their application in diverse tonal and professional contexts, Heinz’ loudspeaker designs have always stayed true to the same ideal of sonic excellence: they have, above all, always 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 the product development department at HEDD | Heinz Electrodynamic Designs is fully committed to the idea of creating versatile and surgically precise studio monitors that producers and sound engineers from a wide array of musical branches can use as tools for their audio monitoring processes. HEDD’s loudspeakers can thus be understood as the newest and most advanced products that Klaus Heinz and his team have developed over the years.


Not only are HEDD’s loudspeakers produced in Berlin, they also feature an unprecedented level of digital signal optimization (HEDD Lineariser®) and connectivity (HEDD Bridge), improved diaphragm materials as well as ultra-efficient amplifiers. Last but not least, these brand-new studio monitors take another technological step in the development of the Air Motion Transformer. 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.

The HEDD team consists of musicians and loudspeaker nerds, electrical engineers, graphic designers, and admin pros, all of whom are fully committed to the creation of this new brand.
