Are parts still available for vintage Klipsch?

I recently found a pair of Klipsch Cornwalls for $130.00 at a pawn shop. The cabinets have seen better days but, I can always refinish or paint them. The grills are in good shape and they sound great. My question is, are parts still available for these 30+ year old speakers? I have not talked to anyone at Klipsch as of yet. Does anyone know if woofers and horns are still available? I would like to have them checked out and have new binding posts installed but, I don't want to spend too much money if they were to suddenly die. Jim
