Even with a cat's front claws removed, you're not out of the woods. Several years ago, my declawed cat jumped on top of my speaker, and the back claws got the tweeter. Had to remove the tweeter and send it off for repairs.
So: (1) Get the front claws removed, and (2) keep some boxes on top the speakers when not in use, to discourage the cat from jumping on top of it. Corona 12-pack boxes are great for this. I've never had a problem since.
