Would center channel benefit audio only room?

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.

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.

If you are going to cop an attitude like that, Orpheus10, why even come on this forum and ask for help? You have been asked to simply provide more information about your set-up and your end goals, and you respond with a tone I am accustomed to hearing from a 14 year-old. Go figure.

Good luck with your quest.
