Hello everyone.
After reading a few posts about surrounds, foam vs cloth vs rubber and their life expectancy, I thought I would add a comment. I have had my JBL S/3100 for over 20 yrs now and the aquaplased foam surrounds still look and sound like new. I am not surprised by this as it is what I would have expected but I often do hear about surrounds drying up and splitting. I wonder if the coating has anything to do with this or is it that I do not listen at high levels? In any case, I am very happy about it and hope they will last as long as I do (I'm 71 now).
Still loving the 3100!
