Jamo cbr 1702 re-furbishing

Hey Oakes, recently got a set of speakers Jamo cbr 1702; really nice speakers but the woofer and midrange speakers are worst for wear, they are old speakers and in need of some tlc I think I need to get them re-conned or something (not sure what you call it but the spungy sides of the speakers are all perished), any idea who might be able to do a good job at fixing them for me, I'm in jhb north, but dont mind travelling to get it done right.  thanks.
