I have a couple more thoughts here: M&K S150C Centre Channels and S150AC Angled Centre Channels Now the standard right and left S150 speakers are complementarily angled in the horizontal plane to give a bit of automatic "shoe in". The standard centres are not angled in any way and have a square front baffle. Are there any comments or possible benefits in having 3 identical centre speakers instead of the normal LCR? According to the M&K site the angled centres have the front baffle angled 7.5 degrees in the vertical plane. Alternatively what about three angled centres either wallmounted above the TV angled to point down or wallmounted below the TV and angled to point up? Could you therefore have the 3 identical fronts positioned side by side right next to each other? I assume an SPL can still be used to fine tune. The latter approach will help with placement because ear height is a difficult height for me to place the front speakers. They need to be higher or preferably lower. I know it is very theoretical: are forum members more traditional in the positioning of the front speakers?
