Call me crazy but I have lots of experience using two speakers for the centre channel and in no case did the sound ever appear to come from two distinct points. In fact it appears to come from a point halfway between the two speakers (ie. centered on the screen.)

In one set-up I had two speakers, one velcroed to each side of an HDTV. The vocals appeared to come from the screen, and not from two different points.

I currently use two 60lb floor standing full range 33" speakers, aligned tweeter to tweeter, suspended above my HDTV, in a custom built frame, achored to the wall and tethered to the ceiling. Vocals appear to come from the centre line of the screen - and not as two point sources.

Take amy two speakers and make an equilateral triangle with them and yourself. Play a mono vocal source. What do you hear? Answer: sound coming from mid-way between the two speakers.

curegeorg: what is your personal experience with using two centre channel speakers?
