So after I saw the Youtube video by Tech Ingredients on these DMLs a couple of weeks ago I was instantly intrigued. Since then i ordered two Visaton ex60s for first experiments and started to build some XPS panals.
I already experienced some of the properties these panels have. The LF for example get much stronger when using 30mm thick material compared to 20mm XPS, also overall volume is really dependent on panal size. All of that is probably nothing new to you but never the less fascinating to experience in person.
Now to my questions: Has anyone of you tried the method described in the video, where weights are placed to dampen some of the resonances? I see Bertagni has implemented something similar... I guess.
What thicknes of endgrain Balsa would be appropriate? In some other forum a person chose 3mm and said that thicker panals would make it sound slow/mushi? but in the video ist seems to be about 1/2". This material should also be interesting for a cfk laminate I can imagine (good dampening of the cfk resonaces) ? Kind of like tectonics panels.
After my order was already placed I read that the Visaton do not produce the best sound quality (still very impressed by the result),so for later builds I would chose a different one. Any suggestions? Is the Dayton Ultra still the one with the best "Hifi" potential or are there others that don't break that often?
I am really looking forward to your replies! In the meantime I will start reading on this paper which seems to be very informative: https://urresearch.rochester.edu/fileDownloadForInstitutionalItem.action?itemId=32717&itemFileId=182509
