HRTFs are used on the front speakers. The fronts basically do similar processing as they do in 2 speaker mode until the sound moves in the region behind you. At that point the rear speakers kick in to fill in panning information for the behind locations. This gives you the best of both worlds: nice spread, immersion and some up/down by using HRTFs on the fronts, and strong behind cues from the rear speakers. - Updated: November 29, 1999
