Fathom® - f112-GLOSS - Home Audio - Powered Subwoofers - JL Audio: These guys make the best subs. Musical but will literally shake your house violently during movie action scenes. No weaknesses. The first sub I've owned where I actually had to turn down the intensity. This after finding all the pictures on the wall hanging sideways lights on after the opening sequence of Flight of the Intruder - no lie, my pants were flapping - that is some serious low energy! Awesome.
