After a cold night in the garage (the speakers, not me...), this morning I unloaded them with the help of my son and moved them to the basement.
After looking at them in detail, performing the whole SDA check list including resistance measures, and obviously listening to them, I can say they are in great shape. Next step will be to upgrade the tweeters, since the highs at loud volumes do sound somehow annoying compared with my 1B's that have the new tweeters.
I took all the drivers out and they look like new; noticed that all the wire terminals were really loose, so I tightened them. Could not take any of the tweeters out, because all of them have at least one very damaged hex screw......when I get the new ones some drilling might be needed :)
Also unscrewed the crossovers just to take a peek....and even though I had plans to upgrade them with solen/mills, I must say that I don't think I'll have the courage to do this....all the wires that go to drivers/tweeters are soldered, and just taking the crossovers out will require some surgical work..I think I'll pass...I have soldered some easy connections, but I think this is too much for me...we'll see.
The black gloss looks great IMO; there are a few scratches, some really bad, but nothing that cannot be fixed.
Did I say they sound great? Oh my God; my 1B's with new tweeters (and all 8 new drivers also....) sound great, but the presence of the SRS's is unbelievable. You really feel surrounded by instruments.
Some pictures at home; including the bad scratches...
Edit: One of them is missing one of the adjustable feet (?); anyone knows if I can get an original somewhere?
