And fwiw, so is a PS3. That little plastic ring is there to dampen overtones. Granted it's not a big foam ring....and certainly not the same extent as stuffing the bass drum with a blanket, but it's still a pre-muffled head nonetheless.
Like I said, they used little to no muffling. Felt strip is nothing compared to these pathetic glued on foam rings I keep reading about falling apart.
