I've been going through this same search... first, as was mentioned before, Master & Commander is out now
on Blu-Ray. I don't have this one yet, but do plan on getting it on Netflix and most likely ultimately buying it.
One of the best room-filling bass scenes I have heard is on the Hitman Blu-Ray. There is a gunfight scene that includes a background soundtrack that just plain rumbles the room. The scene runs about 2-3 minutes. For me, it's better than the Blackhawk down scene, which I also like, but it's not quite as good. Hitman is currently my #1 demo disc for this scene. Highly recommended.
