Yes the saucepan is simply a convenient diameter to rest the speaker on during removal of the dust cap and drying time of the epoxy, keeps any pressure off the cone and coil.
When I saw the cone in the pot, along with the comment about softening the glue, I was picturing heating the glue on the stove top. I have to say that I’m a bit disappointed that the real answer is less exotic. It seemed like it might have been a opportunity to learn a new technique. LOL.
I’m looking forward to seeing the final, successful repair.
