Buttkicker or Aura Bass Shaker.

There's no comparison - the Buttkicker is much better than the Aura. You have to make sure that you have a 30Hz high pass somewhere in the signal chain, as the impedance of the BK drops a lot, which tends to let the magic smoke out of amplifiers (except Macrotech 3600s).
