Buy someAC filter foam and glue it to the baffle. Don’t forget to remove the old foam first.  The speakers were probably voiced with foam so I would not use felt unless you want to alter the sound.

I'd call the manufacturer first and see if they have repair kits or use something like this or make one from sheet stock.
