Heinz ElectroDynamic Designs (HEDD) is a high-end audio manufacturer founded by Klaus Heinz (former ADAM Audio developer) and Dr. Frederik Knop. Drawing on a rich history in audio creation and reproduction, the German company builds handcrafted professional studio monitors and headphones in Berlin since 2016. HEDD’s advantage is the in-house developed signature Air Motion Transformer driver, HEDD Lineariser® and CoP Technology, as well as introducing an entire Phase Linear Sub-Satellite System.

The 2021 Debut of HEDD Audio's BASS 12

The BASS 12 (12“ honeycomb woofer) is an extremely powerful subwoofer that extends the low-frequency range of any midfield or main monitors down to 20Hz, and is designed for midsized and larger control rooms. Not only maximising the full potential of the new HEDD MK2 Series, but the BASS 12 can be seamlessly combined to previous HEDD models, as well as any other active monitor speaker system. The BASS 12 houses a robust 12" woofer with a 2.5" voice coil driven by a 700W ICE Power amplifier.

Equipped with a powerful DSP board, HEDD BASS 12 enjoys the same three exciting features shared with MK2 Monitor Series: 

1. HEDD Lineariser®

The HEDD Lineariser® function, that is now built-in to the speaker, which flattens the phase response, creating perfect impulse response. This dramatically helps with spatial reproduction opening up the stereo image offered by your speakers. 

2. >>CoP<< Technology

HEDD's innovative CoP technology give users (for the time) the option to choose from closed or ported cabinets, so you can adjust the bass response to suit your preferences. The speakers come with removable plugs for the bass ports, combined with DSP-based FIR filtering. By opening or closing the ports and setting the switch at the back accordingly, you can switch between optimum accuracy (closed cabinet) and a dynamic, low-reaching design with increased SPL (ported cabinet).


HEDD Audio introduces a completely phase linear Sub-Satellite System. This feature tries to improve the relationship with HEDD subwoofers using Group Delay Compensation to compensate for the distance between speakers and subwoofers and create Linear Subwoofer / Satellite system. Listeners can compensate eventual distances between subwoofers and satellites to stay with linear phase reproduction for the complete system.


Engineered and tested in Berlin to the highest standards. HEDD's new Mk2 and BASS Series combines handcrafted loudspeakers with cutting-edge innovations across the entire range. Based on a strong unibody casing for better durability and satin lacquer-finished ensures that the cabinet remains stable and provides effortless audio, even at full power. Sourced from Denmark the ICE Power amplifier offers 900W and is universally powered for compatibility anywhere in the world.
