Extremis has some pretty impressive xmech, although the Seas is not far behind.
Also ran a high power sine sweep from 20 to 100hz, both drivers do rattle and buzz a little bit but it's actually pretty good as far as mid/basses go (that I've heard). I have some other drivers here that sound like a helicopter taking off
and of course a Koda 10" that's dead silent.
