These excellent
speaker grills are printed from Carbon-fiber-reinforced polycarbonate, but I don't like their open design or hex pattern. So I bought some Aluminum mesh that's similar to the front speakers' molded grills (but about twice as coarse), and some acoustically-transparent cloth, and wrapped the grills. I think they look much closer to stock, although they'd certainly be improved by finer mesh and an outer bezel like the front grills have.
