Hey guys,
after receiving some helpful info in my first post, I now have a chance to contribute a bit of my own.
Recently I bought a "new" set of MW 6502's & decided I'd take some time to use Polksaladanni's JB Weld insurance policy (http://www.polkaudio.com/forums/showthread.php?t=73629&highlight=magnet) on my 4 drivers before they failed.
However, I began doubting that the location shown in his pictures was the correct area to glue when compared to the repair shown here (http://www.audiokarma.org/forums/showthread.php?t=130808).
So as I began prying on my seized driver, It popped apart & guess what?

That's not the right spot!
So please update, your bookmarks, stop the presses & make note of how these things separate. ;)
The "inner plate" is not likely to ever shift as it has 4 solid mechanical attachments to the basket. What does fail, however, is the magnet & back plate (pole piece) just behind it. My picture is a little blurry, but you can see the original ring of glue on the magnet.
So if you'd like to help protect your drivers against the slip of death, apply a generous bead of JB Weld to the following areas:
1. Where the magnet ring meets the inner plate
2. Where the magnet ring meets the outer plate (pole piece)
And Polksaladanni, thanks for the JB Weld idea & I hope you'll forgive me for the correction. :)
