Would center channel benefit audio only room?

onhwy61, the fireplace is the only thing that will explain my soundstage. It is at a proper height on both sides of the fireplace which is in the middle. Since all things are relative, I can lay on the floor and listen, that way my soundstage will be up high.

Orpheus10, Just start a fire in the fire place. The rising heat waves will taking the sound waves with them and you will thusly have great soundstage height. And you will have a pretty fire to watch and not think about that hole in the wall so much. :-)

Perhaps some 2d 3d diffusors from rpg are worth a try.
