Sound "appears" to come from far left and right, well outside the speaker placement width.
It also appears behind the speakers, in front of the speakers, apparent height is also heard, and if you have a nice setup you can actually hear sound that appears to come from behind the listener.
You don't need expensive equipment to hear this. A definitely not audiophile, fully studio manufactured, recording I use for a lot of demos is Led Zeppelin II, side one. If you can't hear the swirling up and behind your head on track 1 your speakers/room are not set up properly.
Chesky demonstration disks can show all of this.
