They have an interesting article on hearing that talks about barn owls and how they have one ear above eye level that points down, and the other ear is below eye level that points up. This allows them to hear up or down sounds which in turn allows them to hone in on where the sound is coming from very accurately.

I was thinking it would be worth checking out propping one speaker up on a cd case at the front, then propping the other up 2 cd's at the back and one cd at the front. This puts them facing slighty up/down with a little difference in the level as well. I'm not sure if it's helping imaging, but I'm going to play with it a bit more.

I'd be interested in hearing if anyone has played with this before.
