Manufacturer's Description from HEDD

The Type 05 model is a real multitasker. Its strong performance, digital connectivity, and compact size turn it into the ideal choice for mobile broadcast stations, recording studios, multichannel-setups, and VoIP conferences. The Type 05 is based on a 2-way-system that provides a solid fundament and a high degree of accuracy in the frequency range between 45Hz and 50kHZ by coordinating the interplay between a 6“-woofer and a high-resolution Air Motion Transformer (HEDD AMT).


Type 05 is, like all of our Series ONE studio monitors, additionally equipped with a modular connection system. Besides standard analog XLR and RCA connections, the Type 05 features an empty card slot that we have designed to read Dante (Audio-over-IP) and other digital audio protocols.



Implemented in the MK2 and subwoofer models is the HEDD Lineariser®, a phase linearisation tool that leads to perfect impulse responses andan audibly improved spatial reproduction.


»CoP« TECHNOLOGY (Closed or Ported)

Ever since there have been loudspeakers, there have been 2 different design approaches toget a good bass response: closed box design, sometimes called infinite baffle, and bass reflexspeakers, or ported designs. By offering removable plugs for the bass ports, combined withadvanced FIR (Finite Impulse Response filtering), we now give our users the choice betweenthese two worlds: A pin-point transient response / optimum accuracy (closed cabinetapproach) or the advantages of a dynamic and low-reaching bass-ported design withincreased SPL.



(GDC for Group Delay Compensation)

We are introducing a completely phase linear Sat-Sub system, a real first. These are the first Satellite Sub systems that are completely “...right in time” by applying switchable group delay at the satellite output. The potential listener distances between subwoofers and satellites can be compensated in a ± 2 m range, together with HEDD MK2 monitors a Linear Phase satellite system can be realized.




About Manufacturer

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.
