From what I've experimented with, the server scene from the movie Pulse can be especially difficult for even good subs when it comes to port noise. The repetitive, droning sound, which I believe is right at 16-17Hz, is right around the port tune of many quality subs. It's a demanding scene that pushes a lot of air.
