The Aura's have a good punch, but, when I get my dream HT done I might upgrade to the Buttkickers as I have a couple of Carver amps not being used that put out 250 watts per channel or 500 when bridged...
Wow, mounted to the side of the waterbed, awesome... going to have to drain and mount underneath (will likely steal one from my HT & order another to replace)...
