It sounds like the woofers have fairly standard foam surrounds. There are several places where you can buy new surrounds with instructions on how to replace. The new parts for last pair I did for a friend cost $30 delivered.
There are also many people who will do this for you. Figure a $100 or perhaps a bit more for a pair.
No need to replace the whole driver if only the surrounds have deteriorated with age.
