Thanks all.
Pops: It happened in every recording I listened to -- about 6 or 7 different ones. There were two sources (CDP and computer), one amp. But the salesman listened with me and then again later and was convinced that there is an audible problem. Believe me, if he had ben able to make it go away by switching amps or some such, he would have, because he knew I would have bought them.
Don't harsh on the dealer. They took them in on trade having been told they were not working -- as a favor to the client upgrading. When I called asking if they had any used speakers I might be interested in, they didn't even mention them. They had some others I wanted to check out. When I got there, I saw the 3.6s -- which I have wanted but haven't shown up locally -- and was told they didn't work, and were likely to be sold as cabinets alone. I asked what was wrong and whether they could be fixed. they said they'd check them out. When I called a couple days later they said that much to their surprise they were working. So I went for a listen, and discerned the balance issue, which was subtle, but pretty definite once you became aware of it.
Surely these speakers can be fixed! The question is whether I should undertake to get that done without knowing exactly what the problem is. And so far you 'gonners seem to think I should not.
