Don't get steel wool anywhere near a speaker! All it takes is a few fragments to migrate onto the speakers cone - over time it will work it's way thru the cone or dome into the VC gap - not a good thing. Had several customers trash their speakers by refinishing them with drivers in place. If you're going to refinish a cabinet with anything ferrous - remove the drivers first and before you remount them go over the whole cabinet (inside and out) with a magnet to pick up ant stray bits.
