how to remove tower speaker grill

these speakers stopped working. i know there is power at the wire so i am guessing the speakers are no go. could someone tell me if i can remove these grills? or can they be?

Yes you can take the grills out. I took mine out to paint them. Use a small screwdriver and start prying gently around where the mesh and the black ring touch working your way all the way around the speaker. Take your time and be gentle they will come out.
