Query: Tight powerful bass

This is the best reasonably priced powered subwoofer around. It has tons of power and gives a nice tigght bass sound - not overly boomy. There is a dial on the top to adjust output. (My daughter LOVES to play with the dial when we are not looking . . .)The only reason I deducted one star is that the subwoofer is always powered on. It does not have a circuit to simply sense when there is a signal to power itself on. Others have that, but I'm sure it uses very little power when not in use.It is heavy and looks great.
