Were these ever measured anywhere? I'd love to see a waterfall chart of the bass region.
I've tried my favorite damping material, cotton, on the cup and while it does help tame the treble down I don't think it help the upper bass, it still sounds a bit blurred. Be careful with damping the cup though as it could reduce the sound stage significantly, and dynamat is notoriously hard to remove, maybe you could try with blutack first to be safe.
Beside the one on the back of the box I don't think anyone has ever measured HP100 unfortunately.
