They all have, like most movies, STRONG bass in the mid 20's with some lower levels in the 15 to 20 Hz range. When you watch the graph, for example, with "The Incredibles", you can see the 115 dB stuff at 28 Hz with some 95-100 dB stuff in the 15-20 Hz range.

By the way, I am liking this subwoofer a LOT.
