The HEDD Type 40 Main Studio Monitors bring flagship monitoring performance to professional recording, mixing, and mastering studios in a remarkably compact, full-range design.
Taking over from the acclaimed TYPE 30 MK2, these powerful three-way active studio monitors combine HEDD's signature hand-built Air Motion Transformer (AMT) tweeter, high-performance midrange drivers, and a massive high-excursion woofer to deliver exceptional clarity, precise imaging, and deep, controlled bass response. With 1300 watts of DSP-controlled amplification per speaker, advanced HEDD Lineariser technology, and a sealed cabinet design that reaches all the way down to 20 Hz, the Type 40 Main delivers the authority and accuracy of a large-format main monitoring system without demanding a massive control room. Whether you're making critical mastering decisions, dialing in the perfect mix, or simply wanting to hear every detail of your recordings, the Type 40 Main provides the confidence to get it right. At the heart of the HEDD Type 40 Main is an advanced three-way driver configuration featuring a 10¾-inch high-excursion woofer, dual 4-inch midrange drivers, and Klaus Heinz's renowned Air Motion Transformer tweeter. The symmetrical D'Appolito MTM arrangement positions the AMT between the two midrange drivers, creating a focused acoustic center with controlled vertical dispersion and a consistent horizontal listening window. This carefully engineered design helps minimize unwanted floor and ceiling reflections while delivering exceptional stereo imaging and accurate instrument placement. The fully sealed enclosure provides tight, articulate low-frequency reproduction with excellent pitch definition, making it easier to evaluate kick drums, bass guitars, and sub-bass information without relying on a separate subwoofer. The result is a truly full-range reference monitor that offers outstanding performance in professional control rooms, including spaces around 20–30 square meters. The Type 40 Main also incorporates HEDD's sophisticated DSP processing and Lineariser technology, providing precise control over frequency response, phase alignment, and transient accuracy. The Lineariser's zero-phase mode uses advanced FIR-based processing to time-align the drivers, creating a coherent acoustic response with exceptional imaging and detail. Additional operating modes include Flat for frequency-response correction without phase linearization and Off for minimum latency during tracking and real-time performance. HEDD CTRL software adds convenient remote system management, allowing engineers to adjust monitor settings, optimize performance for their listening environment, and save presets for different workflows. Balanced analog XLR and digital AES/EBU connectivity provide flexible integration into modern studio systems, while onboard shelving and desk filters offer additional room-tuning capabilities. And when your studio needs even more output and low-frequency headroom, the modular Type 40 platform can expand with up to three optional Type 40 XTD extension modules per side. Designed and assembled in Berlin, the HEDD Type 40 Main represents a serious monitoring solution for engineers who demand uncompromising accuracy, powerful performance, and room to grow.
