Well congrats! Let us know how you like it. You're right, the Ultra is quite the big boy. Mine sort of acts as an end table/lamp stand in the corner of the "L" shape between two couches, so it works out nicely.

I notice though that the PB12 plus is only about an inch smaller in all dimensions! Are we talking about the same sub?
