The bottom ply of the ICE WHITE Reflector uses Aquarian's heavy-duty smooth white 10mil drumhead film which is stiffer and brighter than our standard drumhead material. The top layer uses Aquarian’s Classic Nu-Brite 7 mil film for warmth. The result is a two-ply hybrid head that is warm, resonant and musical at lower volumes; bright and articulate when played hard; clean and focused when played fast!
