Ooohh A subject near and dear to my heart. aa
If I've got one shot at knocking somebodies socks off at low frequency effects (LFE's), it would have to be:
War of the Worlds Pod emergence scene (Chapters 5,6 I believe)
As a couple members here have found out first hand.

If they want some more bass I might play some (two channel music) Japanese drums from:
KODOIt's amazing how much bass can be had from a drum that's 6' across.
Need some more? How about:
Finding NemoThis one you'll want to 'sneak up' on the bass. The chapter with the little girl banging on the aquarium (your perspective is from
inside the aquarium), starts INSTANTLY as soon as the chapter starts. Simply press [next chapter] on your DVD remote as it's not very far into the movie. But careful, it'll damage a sub if you're not careful.

How about another movie? This one with 'tactful' bass (unlike War of the Worlds that's designed to make your pant legs move):
Bad Boys II Chapters 5,6. This is the longest chase/blow.stuff.up/edge.of.your.seat/eye.and.ear.candy scene I've ever seen.
Harry Potter; The "Whomping Willow". Very nice.
As mentioned before, I'll second these...........;
Matrix: Helicopter/building
Blackhawk Down: Crash scene
Master and Commander: Various scenes.....Basically anytime a cannon is fired.
Donald Fagen: Morph the Cat (CD)
Star Wars: Pod Race (cliche at this point I'm sure, but it'll help you get your rocks off)

More, more, more.........there's sooo much more.
Actually, there's a site called "RemoteCentral.com" that has a
several dozen page thread on this very topic, but I can't find it.
Great thread Rob!
