Hi, I would be sparing with the spray but it is not likely to harm anything as long as you keep it off the speaker cones. I doubt that you are generating significant heat inside the enclosures. Figure that about an average of 1-5 watts of power is being dissipated in the speakers unless you are doing something really odd like compressed music at a concert. Then maybe you would see up to 10% of what the amplifier could deliver.
