Page 8: Cop: Closed Or Ported
«CoP» Closed or Ported The HEDD Type 20 MK2 and Type 30 MK2 can be used in either closed or in ported mode. These are two fundamentally different systems that are available for the user to compare and choose. There is no definite better between the two systems. We recommend to compare carefully to find the optimal option for your environment and listening habits. - Page 9 Closed Mode In closed mode the HEDD BASS subwoofer functions as an infinite baffle speaker. This results in a cleaner sound and increased resolution. However, a 6-10 dB reduction in maximum sound pressure level (depending on the audio material) for low frequencies is the consequence.

Satellite Offset With HEDD MK2 monitors and HEDD BASS subwoofers it is possible to build completely linear phase Satellite-Subwoofer set-ups.

Page 20: A Brief History Of Time
A Brief History of Time (within subwoofers, this time) by Klaus Heinz Subwoofer are in use since many decades, their integration into the reproduction chain allows to add fundamental frequencies where small speakers meet their limits. However, the use of separate bass units often shows two typical unwanted side effects: the woofer section appears to be separated or not really integrated into the overall sound image, and the low frequencies themselves tend to sound somewhat boomy or weakened. - Page 21 Impulse Response (IR) of the subwoofer under consideration. The IR’s of BASS 08 and BASS 12 have been measured in the big anechoic chamber of the Technical University Berlin and implemented in the DSP boards to deliver that information.
- Page 22 We think we have found and eliminated the main reasons for inhomogeneous and boomy sound in Satellite-Sub systems. We at HEDD would be happy if you take the time for an audition, the proof as we do know is in the listening.
