for those interested in only the DIY part of it skip the italic section 
a fortunate (IMO) coincidence made me take a look on the local audio forum's advertisement section and that ended up in my buying a pair of used Dynaudio Audience 52 speakers the next day. they have been optically damaged. most likely they have been dropped during transportation to my previous owner which resulted in cracked edges and also both tweeter domes have dents. which is kind of weird considering that the material is some kind of rubber treated fabric - not rigid that is - and it should restore itself to original shape. any idea what might have caused the permanent dents?
considering that they used to cost EUR 800 new (now out of production) and that I couldn't find anything wrong with them sonically I think I paid a good price - EUR 300. maybe many would think that's too high considering the physical issues they have, but the sound is rewarding, detailed yet not forward, exceptionally good soundstage (wide and deep), decent bass and overall very musical and neutral IMO. I know that there are many decent bookshelves that sell for even less than that price but in my town there isn't any dealer so the occasions for listening tests are scarce so I preferred to buy these which I was acquainted to. and I'm satisfied with my decision
and I get to DIY on them a bit too...
now... for the DIY part. they sound waaaay superior to my DIY Morels (see thread here http://www.diyaudio.com/forums/mult...parts-zaph-seas-l18-seas-27tbfcg-speaker.html).
but I'm going to experiment a bit.
first I'll reverse engineer everything and post everything unless the mods think I shouldn't
meaning box params, filters, drivers and box measruremets (now why did I sell my ECM 8000?).
then I'll restore them, re-veneer and cover the baffle with leather imitation.
but first... I'll just replace the tweeters with my MDT32S Morels just out of curiosity, maybe they work. I haven't measured the Dynaudio tweeters (only Re which is nearly identical) but who knows?
fortunately the face place diameter is nearly identical (less than 1 mm difference). I just need to drill 3 more holes (the offset of the mounting holes is slightly larger on the Morels) and that's it.
in the end this will be my reference for tweaking the Morels and getting them to sound better. I want to understand how Dynaudio did it. after all Vance Dickason himself says that one needs to have a reference.
will get back with more pics and reports on the replacement later.
