Fixing Vandersteen 2c's?

My father has handed down his old 2C(maybe Ce)'s to me. They are shot to sh**. I'm guessing that the woofers and tweeters are possibly blown. The only Vandersteen dealer near me is 2 hours away. I'm wondering if anyone knows of an economical way to fix these up. Do I need to use genuine Vandersteen replacement components? Or, is there another, more accessible, brand that is compatible? The shipping to Vandersteen in California would probably eat up half of the money I'm willing to spend here. Thanks.
