Question Adjusting zero position Subwoofer

Dear members,

I have a problem with two ElectroVoice DL18MT subwoofers. The zero position of the cone is to far to the back. The spinner seems a little dry. Does anybody know how to soften or regenerate the spinner and / or the outher ring of the speaker? The spinner seems to be impregnated with a kind of epoxy material. Perhaps a solvent can work.

thanks in advance

I got a pair of speakers where the cone was mis-aligned.

I pushed the cone forward by adding stuff between the basket and the cone. I left it for a couple of nights and it was close enough.
My work:

Acetone will soften the phenolic resin in the spider. Don't overdo it and get it on the glue joints.

If you have an MTL4 it is a good idea to rotate the top and bottom woofers every year or so. Rotate the left and right woofers 180.
