HEDD Audio is thrilled to introduce the TYPE 05 A-CORE and TYPE 07 A-CORE active speakers, our most advanced analog designs to date and a bold new chapter in HEDD Audio’s journey of uncompromising sound. The new 2-way models draw from over 40 years of loudspeaker innovation, beginning with Klaus Heinz’s groundbreaking work on Air Motion Transformer (AMT) technology in the 1970s. Rooted in the brand’s analog heritage yet refined with modern precision, they offer a deliberate take on the fundamentals of sound in a world of increased digital complexity. Handcrafted and assembled in Berlin, A-CORE speakers are built with a dedication to durability, acoustic authenticity, and ease of use.
Premium Components, Proven Performance
At the heart of the TYPE 05 and 07 A-CORE are the same premium components found in the company’s flagship MK2 monitor line and Tower Mains system:
∙ Klaus Heinz’s hand-built Air Motion Transformer tweeter, offering ultra fast transient response and lifelike detail ∙ Custom-made woofers made of Honeycomb compound, delivering tight, articulate mids and unusually deep, controlled lows ∙ A heavy-duty MDF cabinet construction that unlocks the full potential of the drivers, even at high volumes ∙ High-efficiency Class Damplifiers
A-CORE and MK2 models may share components and sonic DNA, but they offer different signal- and workflows. In short: MK2 offers extensive digital control and a level of sonic refinement that is only possible with DSP, whereas A-CORE focuses on immediacy and pure analog performance. A-CORE active monitors are crafted for customers who value ease of use, rock-solid build quality, and honest, emotionally engaging sound. With versatile XLR, TRS, and RCA connectivity and intuitive bass & treble EQs, A-CORE is aimed at artists, sound engineers, and music lovers that just want to create without the tech getting in their way. Just set, connect, and listen.
Trusted by artists such as Q-Tip, top engineers including Heba Kadry (Björk) and Tchad Blake (Arctic Monkeys), and Oscar-winning composers such as Hildur Guðnadóttir (Joker) and Volker Bertelmann (All Quiet on the Western Front), HEDD’s commitment to precision and musicality continues with A-CORE.
