I have to give a shout out to the cave scene in 'Ironman'. After all it kicked off the whole debacle with my EP800 in style. When an EP800 has problems with a scene, you know there's some serious LFE going on boys and girls!
Also, being a big Quentin Tarantino fan, I can tell you that LFE lurks ominously around in his soundtracks. The chase scene in 'Resevior Dogs' where the cops are running down Mr. Pink and as he turns the corner he unloads his entire clip into their general direction... turn that scene up when the old lady isn't paying attention and she'll hit the deck trying to escape the burglar who just broke into your home and opened fire on her!!!
