Hi,

I'm thinking of refoaming a passive radiator of L222. The previous owner had the foam surround glued to the top instead of the under-side of the cone. Maybe it was because he couldn't find the correct foam surround.

My question is, how do I remove the newly done up foam surround? I will try to use a pen knife to try to remove as much foam as possible, but I suspect that would not produce a clean job. Is there some kind of solvent that I can use to clean up the cone and basket edges before I glue the new surround?

Thanks.
