Foam around treble units/ tweeters

My speakers have foam - maybe 1/4 inch thick around the treble/ tweeter units.

Foam is getting old and some fell off. The foam is about 6 by 6 inches and 1/4 inch thick.

Any idea of what type of material to use to replace the foam? What is it used for?

Thank you.

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.
