2008 350 Cabin Speaker Covers

Mich350

I want to inspect and maybe replace the two cabin speakers on each side of the cupboards above the couch.  They have the black felt fabric covering them.  I have tried to gently remove\pull\turn them by hand to remove without success.  Worried about damaging them.  Hoping someone has already done this and can confirm the best method to get to the speakers.
