Yeah, two per driver. The mesh cup actually compresses them slightly too, whereas the RP18 has a solid ~1cm between the damping and the back of the cup. Also, God, every time I put this headphone on after work it just sounds so incredibly "right". So sweet and clear. I don't want to sound like I'm fanboying, but just... wow. It's been months and this headphone is still surprising me. The Z7 never did that... nothing has ever done that.
