The deal is done...
I picked up the speakers this morning. I paid $400 and I couldn't be happier. These speakers are pristine. There isn't a mark on the cabinets, the grill cloth, the drivers, tweeters... They literally look like they could be brand new.
I had planned to take a battery with me this morning so I could fuzz the speaker inputs and make sure the drivers moved... I forgot it this morning. When I got home I did check them... Much to my dismay one of the drivers in the right speaker wasn't moving. I thought about magnet shift but couldn't see how that happened since we were so careful. Anyway, I took the driver out of the cabinet, disconnected the wires from the crossover, and it worked fine. I went ahead and put the driver back in and removed the passive radiator, wiggled the wiring harness a little, and once again fuzzed the speaker. This time the driver moved, but not to the degree the others did. I stopped there, since I plan to upgrade the crossovers and tweeters before I listen to them. I figured something in the crossover was limiting the signal... Not sure if I'm right/wrong, but for now I'm going to go ahead and see what happens.
It looks like these are pin/blade. I have all the original paperwork, cables, etc... that came with them. The previous owner got a heck of a deal when he bought them new... he paid a little over $900 for them in 1990.
Now I need to see about ordering the tweeters and start studying on how to de-solder and re-build the crossovers. Looks like phone calls early next week. Can anyone tell me if the old tweeters are worth anything? Can I sell them on ebay or on here? That would help offset the cost of new.
Thanks again everyone... I am one very happy camper!
