The foam surrounds of a driver can be replaced. Company like Orange County Speaker is a good place to send speakers to be repaired. They have a list of speaker brands, on their web site, that they do repair work on.
As far as replacing those speakers with new ones, you have dozens of choices.
Its been years since I've listened to a EV speaker, so I don't know what brands would have the same basic sound, if that's what you want to go with.
But many speaker companies, that sell over the internet, both ID brands and traditional retail speaker companies, have return policies, so if you don't want to keep the speakers you've bought to do an in home audtition, its just a matter of sending them back.
