They both have name plates, unfortunately it only states SDA 1 Left Channel - Serial Number L SDA 1 7934 and SDA 1 Right Channel - Serial Number R SDA 1 7910. All I know I am very happy. I really liked the Paradigms, and was even contemplating upgrading my 5seMKIII's with a pair of 7seMKIII's that were about 40 minutes away.
These were on Craigslist last week, and I called they guy. He had a higher offer from a guy in Michigan, but he felt that the man may balk once he got the freight quote. Sure enough, he called me Sunday saying the other guy backed out and he had someone else locally email him for what I offered. He called me back because I called first. Talk about KARMA.
Yes, there are some scratches and the grille fabric could be replaced, but sonically these are kick ass. I may have to replace one woofer as it was acting up a little at higher volume when we first hooked it up, but it seems to have gone away (maybe a slight shift in something when moving?) If it appears again, he has some replacement woofers at home, and said to give him a call if it keeps acting up. (So far it has been quiet, so I'll keep my eye on that one).
I have been playing them at a relatively comfortable level (da' rats is in der beds), and they seem to be opening up sonically somewhat from when we first hooked them up. I am truly happy!
