spkr repair
you can difinitely repair them if all materials are intact. there is special speaker glue which can be found in any pro audio hardware store or any P.A. company. (sorry can't give you the name but it is a common item) I have a pair of JBL century 100's, the first studio monitor converted for home use. they are 32 years old, have been reconed and remagnetized and they sound better today (less harsh) than ever. you can't beat pro but, they are never the best bang for the buck.
