The fronts should be placed the same as in 2-speaker mode, i.e. to the sides of your monitor. For cards that don't use HTFTs on the rear it means that the rears are not terribly sensitive to placement, as long as they are behind you, and spread apart from each other. My personal preference is to have them pretty far away from me (they sound more ambient that way because you hear more of the rear sounds reflecting around your room - you're also less likely to trip all over them if they are far away), and spread apart quite a bit. If you have HRTFs on the rear speakers then placement becomes a little more critical with respect to how far apart they are but its not critical. - Updated: November 29, 1999
