Ok. I guess the first step will be to see if I can open up the damn things to get to the crossovers. As for the binding posts, is that a pretty straightforward swap? Anything general I need to know?
In related news, the amp powering these speakers is an Adcom GFA-2, which, as far as I can tell, still works fine with the exception of the blown fuse. I emailed what I thought was the central Adcom parts place and they want $19.95 for the schematic/service manual. That seems kind of cheesy for a 20+ year old amp, doesn't it?
