The formula doesn't work well in my room b/c the speakers would then be in the middle of the room, not too wife friendly. The 7-9 feet seems a little more then where I am now. I think they are around 6'6" center to center, the soundstage improves as I keep adjusting but still not there. They (Vandy 2ce sigs) also sound too harsh with more than an inch of toe-in. I didn't think they would have any center image with 8-9' ft of spacing center to center. I'll continue moving them around & see where it gets me I just didn't know where most folks are running their speakers as a general rule of thumb.
What determines speaker distance?
What determines the spacing between the speakers? I've seen a 1.3 formula for setting the distance between each. If I have a 9 foot distance from the speakers to the listening chair that would make the spacing approx 7 feet? Seems a little wide to get a good soundstage. Are there are any other "general" guidelines for getting a basic spacing between the two?
