I just finished resurrecting an H13 10-1/2 Inch speaker for my 650. The original opt was bad and the cone & spider was bent out of shape but the vc and field coil were good. I had planned to attempt a recone when I found an opt and Philco 650 at an estate sale for ten bucks. The cone fit perfectly in my original frame. I used contact cement around the cone's flexible edge to reinforce the paper. I left the cone slightly loose with the speaker face down on the workbench and played the radio on and off for about a week to see if some distortion could be alleviated and it worked. The vc had centered itself.
The gap for the voice coil was really dirty. I used a thin feeler gauge with a vacuum cleaner to get it clean.
