Today my 8 inch speaker cones arrived from MAT Electronics, and I re-coned the speaker. It was actually fairly easy because the original spider and voice coil on mine was perfect despite the rest of the old cone being in shreds. All I had to do was trim a tiny bit from the outside of the cone mounting edge so it would fit in the frame. Then I carefully glued the original spider / voice coil assembly to the very center of the new cone using 2 part, 5 minute epoxy. One must be very careful to center the coil in the center hole of the cone, inserting it through the front of the cone. Once the assembly was centered well and beginning to stiffen, I let it dry suspended on a pencil standing straight up, with the point through the center screw hole of the spider, so that gravity would let he cone weight hold it on the spider assembly. Once the voice coil had set up to the cone, I then reassembled the cone into the speaker frame, and glued the outer edge of the suspension to the edge of the frame, again using 5 minute epoxy. One must keep going back and making sure the suspension glues down well all the way around, but eventually it will. I do notice that the speaker suspension foam is a tiny bit higher than the edge of the frame, so I will have to make 1/4 inch spacers for the 4 mounting screws.  I will have to wait now until the radio is all fixed to see how it sounds. My process was similar to this guys, but with less headaches...  https://www.youtube.com/watch?v=H023zMrYDTU  .
