I removed the magnet cover off the back of the 15" woofer and see a large aluminum color surface almost as big as the cover itself,, is this just covering the magnet or is it part of the actual magnet,, photo below,,

when I place a screwdriver next to it there is very little attraction,, have read here on the forum about having them recharged,,

what about the magnet in the horn, are the of the same character losing their strength with age,, reminds me of my own body,,

the magnets in my old AR2As that I just reworked from the late 60s, I could hardly pull the screwdriver off those 11" woofers and can't imagine them being much stronger when new,,

thanks
