A-CORE Our Most Advanced Analog Speakers Yet
The A-CORE Series distills over 40 years of loudspeaker design by HEDD founder Klaus Heinz into a new generation of pure analog monitors.
Hand-assembled in Berlin and made with the same premium components found in HEDD’s MK2 series — including the acclaimed Air Motion Transformer tweeter and custom Honeycomb woofers — A-CORE delivers stunning detail, low-latency performance, and great musicality, without digital processing or software reliance.
A-CORE is designed for creators who want the essentials: high-resolution sound, reliability, and simplicity. Whether you're in a home studio, DJ booth, or immersive setup, A-CORE speakers integrate seamlessly and let you focus on what really matters.
TYPE 05 A-CORE Analog bliss in a compact form
The TYPE 05 A-CORE is the compact model in the series — engineered for smaller spaces without sacrificing performance. It pairs HEDD’s signature AMT tweeter with a 5” custom Honeycomb woofer, delivering exceptionally clear mids and highs with surprisingly deep bass extension (down to 43 Hz). Its plug-and-play design, analog signal path, and minimal footprint make it ideal for creating in the nearfield, portable setups, and compact Atmos configurations.
KEY FEATURES
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.
