The opening scenes in "Master and Commander" are great for checking out your sub. The creaking floorboards and creaking ropes floating around the room are suddenly overwhelmed by the cannon shots followed by the strikes of the cannon balls hitting the ship. As my son would say: "woof"
The opening battle scenes in "Gladiator" get the job done as well, as does the "The Fifth Element"
There is some pretty good low frequency information happening in parts of "Blade Runner" too....
If you are into it, the "Drumz/Space" section of the Grateful Dead DVD "Truckin' Off To Buffalo" will energize your room.
