Blown tweeter B&W DM2000

Anyone know of an aftermarket replacement that might work for a B&W DM2000? It's an older speaker and of course the tweeters are long out of production at B&W.

thanks so much in advance.
Are you sure they are blown? Did it just happen - if so have you given the protection circuits 24 hours to reset themselves?
Those were my first speakers many years ago and my brother still uses them today. If you activated the protection circuit it takes a while for it to reset itself. Maybe someone else can add input on aftermarket tweeters if blown.
Good luck.
