I think that width which is offered in Trifield has to be the soundstage.

Ie: as you move the center speaker away from the screen it is often a term used that the soundstange becomes wider (greater less centered)

I have found since I did my last room correction and also adjusted the phase of each speaker that the phantom center is not there but its more across the front 3.

My question is: When setting the phase I was told by Meridian that I should choose the sound that was wider. So naturally when you add all those wider speaker settings you will have a wider result and lose the phantom center

Is there another way to select which way a speaker should sound with phase. Some are negative and some positive in my system with no sense to it. ?
