"It's a scene in "Finding Nemo" where a Little girl (Darla) taps on the glass of an aquarium. It is an incredible LFE (Low Frequency Effect) which rattles walls, and is considered a good test of a subwoofer's ability."

And a good test of the structural rigidity of your house. You'll find rattles you've never heard before.
