I got some thin flexible foam and cut a surround out 9" inner 10.5 " outer.

I used some adhesive from another surround I did (good stuff)

After several hours spent clearing old adhesive off of the cone, I glued the surround onto the cone, using a small plastic ruler to press up from below the surround. This process took a couple of hours as I had to do a little at a time. Let that dry overnight

Next day I hooked up an amp and CD player to the speaker, applied the glue to the outer surround-to-frame edge. Playing the 30Hz test tone allowed me to align the cone as to not touch the coil. Each ten minutes I test again to make sure. Also test in horizontal position as this is the normal position of the speaker

I also cut out a 4mm thick ring of open cell foam to use as the gasket

I'll re-install the speaker after it cures

VICTORY! It sounds fantastic

The multi-sonic control is effective and the base is sweet and controlled

The gaskets are important to flush the speaker against the cabinet

I think I spent 30 hours of labor on fixing the woofer alone
