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.
