Yeah, all of the 20 speakers have the stiff internal spider.

Two sources for speaker cones:

MAT Electronics also carries external accordion spiders.

There are other sources for these as well, I am sure.

I have yet to find a source for cones suitable for use in the 10-1/2 inch diameter Philco speakers. 10 inch cones are too small, 12 inch cones are too big.

I've only done a little bit of reconing for myself, and only 8 inch speakers so far. I consider my reconing work to still be in the sloppy stage, compared to a pro such as Hank Brazeal, But so far, all but one have turned out really well as far as sound quality is concerned. I'll eventually redo the one that did not turn out so well...
