Yes.
Many "reconing" companies exist. They can replace the entire cone, but that is expensive. (usually good classic speakers have this done to them) You can buy just the foam surround too, and using rubber cement glue it in. You MUST make certain that the cone is centered properly or it may rub the voice coil and make icky noises. (playing the speaker with no surround present is very very bad for the voice coil, it may wear out from rubbing, and ruin the speaker)
I have a friend, who has some $30 big old JBLs. we "repaired" the surround with many many bits of duct tape cut in trapezoid shape and making a large enough curved lip to let them work pretty well for $30 speakers. They have been in use for at least 5 years that way... no complaints.
