Okay, this is gonna sound like a dumb question....because that's what it is. Nothing new for me.
AverageJoe and I were munching down some bacon and eggs yesterday and were discussing speaker performance. (It doesn't get much better than that!

) We got to talking about soundstage and speaker effects...such as the below deck scene in Master And Commander where you can hear footsteps on the ship's deck above the actors (who were stowing gear and loading cannons, etc). So just how does a speaker, even in DD 5.1, make you think you're hearing footsteps
over your head when your speakers are at ear level?? Auditory illusion?
