That is a good idea. I'll do that tonight. Yes, the bad drivers are on the same side. One is completely dead, and the other seems to be going out. I'll hook up the network to the other speaker, which I believe is good, then see if the tone is the same. As for the deal, I essentially got them for free, so spending $350 or so isn't too big a deal, but the wife will not be happy.
Thanks everyone!
