HEDD Audio Type 20 A-Core marks a significant step forward in the brand’s professional monitoring lineup, delivering a powerful three-way studio monitor designed for larger studios, mixing rooms, and mastering environments. Built around a fully analogue signal path, it focuses on accuracy, headroom, and musical integrity without relying on digital signal processing.
A Three-Way Monitor Built for Serious Studios
The Type 20 A-Core has been developed to meet the demands of professionals who require detailed sound reproduction at higher listening levels and across larger spaces. As part of the A-Core series, it strips away onboard DSP to concentrate on core acoustic performance, offering a latency-free workflow that integrates naturally into both analogue and hybrid studio setups.
This approach reflects HEDD Audio’s philosophy of combining traditional analogue design with advanced transducer technology. Drawing on the engineering foundations of the company’s flagship MK2 and Tower Mains systems, the Type 20 A-Core delivers a listening experience that emphasizes clarity, depth, and tonal balance. The result is a monitor intended not just for accuracy, but for long, fatigue-free sessions in demanding production contexts.
Advanced Transducer Technology and Amplification
At the heart of the Type 20 A-Core is a carefully engineered three-way configuration. High frequencies are handled by HEDD Audio’s signature Air Motion Transformer tweeter, originally developed by Klaus Heinz. This design is known for its exceptionally fast transient response and smooth, detailed high-end reproduction, making it particularly effective for critical listening and precise mix decisions.
The midrange and low frequencies are driven by custom honeycomb woofers designed to provide tight control, extended low-end reach, and a coherent transition between frequency bands. These drivers are paired with a refined analogue crossover network that preserves natural phase relationships and ensures a cohesive stereo image.
Powering the system are high-quality ICEpower Class-D amplifiers from Denmark. These amplifiers offer a combination of efficiency, reliability, and sonic transparency, allowing the Type 20 A-Core to reach high sound pressure levels without compromising detail or control.
Designed for Accuracy, Flexibility, and Longevity
The enclosure of the Type 20 A-Core is constructed from robust MDF, carefully optimized for airflow and driver performance. This solid cabinet design contributes to reduced resonance and consistent performance over time, supporting both accuracy and durability in professional environments.
Simple bass and treble EQ controls are included to facilitate basic room compensation. These analogue adjustments make it easier to adapt the monitors to different acoustic conditions without introducing latency or complexity. Connectivity is equally versatile, with balanced XLR and TRS inputs alongside unbalanced RCA connections, ensuring compatibility with a wide range of audio interfaces, DJ mixers, and playback systems.
With a frequency response extending down to 32 Hz and maximum output levels reaching up to 120 dB SPL, the Type 20 A-Core is capable of delivering both deep low-end information and high-level monitoring without strain. Each unit is manufactured in Berlin and supported by a five-year warranty, underlining HEDD Audio’s commitment to build quality and long-term reliability.
