Evans Power Center Clear Drum Heads are made out of a single ply of film of different thicknesses depending on the diameter: 10 mils on 6" - 15" heads and 12 mils on 16"/18". This design decision keeps the smaller toms resonant and open, and gives the bigger toms more focus and punch.
These heads also feature a reverse dot that adds more reinforcement, enhancing attack along the way.
