No way to know without testing. It's not just the coil material that sets the power limits, but also the former, the diaphragm and horn, the magnet, the heat conduction properties of material surrounding the coil (ferrofluid or air), how much radiated heat is dissipated and how much air surrounding the coil can convect it away.
