I hear Boss is coming out with subs that handle 1.21 jiggawatts. Might want to save your $ for those. But then you will have to do the thunderstorm mod to your electrical system so you can power your amp with lightning strikes.
One of the reviews on SMD said it will hit so hard, that you will go back in time because the extreme sound pressure rips a hole in the space time continuum. The low notes will hit harder so those will send you farther back in time than the higher notes.
