Scroll down a few post in this link and you'll see the freq waterfall for the Darla tap scene. The red indicates where the strong bass in the 30Hz - 35Hz region. There's bass below 10 Hz, but it's not nearly a strong as the 30 -35Hz stuff.

Great bass scene thats intended to sound like a boom, boom not a tap. Like others have said it's supposed to be from the perspective of being in a tank of water.
