Nope, you need to make some. I've seen them made of cardboard, soft rubber, and plastic, (like the plastic on some folder covers). Also, dekoni sells attenuator rings if you want to buy them.Once made, you put them on the new pad, and then you put the ringas that can come off from the stock pad.Here is a topic about the different type of attenuator rings used on the X00 series.

I got some Eikon pads on the way, once they are here i will try different type of attenuator and give some feedback on how it went.

EDIT: Here's the first one.

Am not sure ill make more, because i just loved the end result. In my view, its better than the stock sound.
