Lol subwoofer isn't nearly as directional as a speaker but its placement definitely has effects on the way you hear it depending on it's position relative to different walls. You don't have to be an audiophile to notice this. The way vibration works and how air moves given subwoofer displacement and it's size, it is actually a very big factor. There are lots of common misconceptions about it as well.
I agree with everything here, guess I just didn't agree w/ how you said "Couldn't be MORE wrong", because he could have been more wrong..lol
