How would I go about removing the spider from the cone?

The spider is glued on the cone and so is the voice coil. I think you can use a cotton swab dipped in acetone and carefully apply the acetone to the edge of the spider. Maybe someone else has a different suggestion.

I can't remember, but there was a particular product for loosening glue on the more modern "spiders", used post-war, and also to loosen the glue that holds the cone to the speaker frame. Can't remember what it was but GC cements used to sell it. Probably the same stuff needed to remove the spider used on a 91.

I'll give the acetone a try and let you know.

I do not have much experience with speakers, but acetone sounds right. It does not affect paper but does dissolve about anything else that has polymers in it, like glues, plastics etc.
