Home-made pepper spray works for me. Spray the area around the speakers as well as the grills (remove the grills, take outside and spray generously). Here is the recipe for the spray:
Mix 1 cup water with about 2 tablespoons dry red pepper flakes (seeds - like the type you would shake on pizza). Microwave until very hot, but not boiling. Let steep and cool overnight (cover with plastic wrap.) When cool, strain off the pepper flakes.
Pour the brew into a small spray bottle for use.
The concoction will make your eyes water and you may sneeze when spraying, so spray quickly and leave the room. When dry, you will not be affected but your cat will not come near that area - ever.
This technique works wonders, is cheap and should not stain darker fabrics (like speaker cloth).
You can use this spray on the sofa arms (etc) as well.
