Hopefully the pictures will explain the process. I bought new cones from Ebay, the second set worked out. You will need a new cone of the right dimensions, speaker gaskets for the rim, plastic shims for the voice coil adjustment, and glue-the kind to refoam speakers. My original cone had been punched out but the voice coil and spider were ok. I also tested all of the other electrical components for continuity. Luckily, everything tested ok for ohms. Speaker cone dimensions: VC diameter 2" cone diameter 11.8"(or very close),depth 2.8". Ebay seller speakerguy2002, cone #7122022-BC.
Carefully remove old cone by cutting it away from the voice coil. DON"T cut the VC leads! The spider is held on by 3 nuts to 3 screws that are loose. Don't worry, the screws won't fall out. Scrape off cone from rim of speaker frame. Clean voice coil gap carefully and check with plastic shims. Go to next post for more.

Check new cone for fit after mounting VC in place using shims to space the VC in the gap. Make sure VC moves freely in gap without shims and then make sure the VC centers properly with the shims. If the cone size matches with no or very little gap, and if the depth is correct, attach spider to frame with the 3 nuts, keeping the shims in place. Glue the cone to the outside of the VC former making sure you get no glue in or near the gap. Allow to dry over night. If you have re-foamed speakers before, the rest is easy. Glue the cone to the rim and glue the gasket to the rim, keeping the shims in place. I use large clips to secure the gasket to the rim. Allow glue to dry thoroughly before proceeding. Remove clips and shims, carefully check cone movement. You should be ready to test. Mine woks perfectly, no rubbing, no noise, just music. I may put on a dust cap to finish the project and give it clean appearance. **Thanks to Mike H. at the Scott Collector site for his advice and encouragement.
