When configuring your speakers in Windows Vista there is a section which says the following:
"Satellite speakers usually have a limited dynamic range and require that they be used with a subwoofer. If your configuration includes full-range speakers, select them below."
You can then choose the placement of any full-range speakers you may have.
Thing is, what the heck is "full-range"? It doesn't define it. I've assumed that most if not all PC speakers don't fall into this category, but I was hoping someone could confirm.
