I use phantom center. I actually have 5 definitive bp8 tower speakers and denon 3805 receiver and no sub, but use 4.0 setup because my current setup doesn't have room for my vertical tower "center". Anyway... I'm looking for a DTS demo in any format (cd, DVD, online mp3 or video) that has voices that circulate through each speaker separately. Sort of like someone saying "left front" in the left front, then "center" in the center channel, etc, etc. Does that exist?
