Bill Legall at MillerSound. He is the BEST at speaker driver repair...period.
Newbee...there are lots of DIY foam surround kits out there. I've tried it myself and totally effed it up, but maybe you would have better luck. I really recommend letting someone who knows how to do it repair it.
Just because it has a foam surround doesn't mean it will be any easier. The foam surrounds are usually a little cheaper than the butyl rubber ones, but they go on the same way.
