Hi, I just picked up a pair of Fisher XP44B speakers, and it looks like the cabinets are about all that is original. My research so far only tells me they might be based on a Wharfedale design. They have 6" woofers and 3" tweeters. If I wanted to refurbish these speakers, any ideas on what kind of drivers I should get? I know the original drivers would be hard to locate, but maybe I could get some recommendations on suitable replacements? I would like something similar to what would have been in them originally, but I don't even know what those are. Any help would be appreciated. I have not looked at the crossovers, but for now I will assume they are shot also. I am not trying to make a top notch audiophile speaker out of these, my budget does not allow it. I would like to make them useable again. I would appreciate any help. Thanks!
