Pernilla,
I think Sean has a great idea (wish I'd thought of it). Another bit of information: there are companies out there that are able to replace the surround (and the spider I imagine) of various drivers. I've not tried any of these services before. Perhaps others at AudiogoN have? That said, it seems that this would be cheaper than replacing the drivers in your speakers and help retain more of the sound that you've enjoyed for so many years.
