home speakers

[liteitup]

Anybody here know anything about rebuilding speakers? I've got some old school speakers that were pretty nice back in the dinosaur days and I'd like to revive them. The company has long since gone out of business and I'm basically clueless about things like crossovers, ohms and frequency responces, etc. I've found a couple of sites on the net that sell parts but I'm sure they're going to ask questions I can't answer.

I'll need a couple of 10" woofers and a couple of tweeters of yet undetermined size.Do crossovers go bad?How would you know? Anything else I need to know?
