Would center channel benefit audio only room?

I have a fireplace in the middle of my front wall with the speakers on either side. The fireplace has no effect on my perception of the size or proportion of the stereo image, which is life size.

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. :-)

Orpheus10, at what decibel level do you listen, and how far from the speakers do you sit?

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

I have a potential solution; it will require: 2 tweeters 3500 to 20K, 1 electronic crossover, 1 small solid state amp fed from 2 output pre. Tweeters will be in ceiling 2ft from fireplace wall, aimed at that wall. The reflected sound will blend and it will emanate from high in the center channel where I want it. I hope this will give you brilliant people out there something to ruminate on.
