what to do with a pair of AR-9's

When I was 16 I was able to save enough to purchase a used pair of Acoustic Research AR-9's. Today I am 28 and upon returning to my Parents house and uncovering the gentle giants, I find have found all of the cone type drivers (four passive side firing 12's and a pair of 8 inch lower mids) have dry rotted away. I though I might try to install new surrounds but my non-audiophile father tried to repair them himself and accidently dissolved what little foam was left. I fear that even if the surrounds were replaced there may be permanent damage to the voice coils. I am therefore hoping that someone could suggest some moderate to low cost replacement drivers. If I can repair them they will become a background music speaker in our living room. If not does anyone need a large pair of cabinets with crossovers and high range drivers? I need help. My wife (Emily) thinks this is a lost cause) Thanks, Curt
