There are some light marks on one of my L19's LF surrounds that could be the first signs of rot. It is only over a 3-inch area and the rest of the surround appears fine, as does the other woofer. The seller thinks they have never been refoamed, so it would be long overdue.
Is it ok to go on using the speaker until it gets worse (if that's what it is) or should I get them done soon?
Thanks
