You are right, the KH310A, is sold that way. You can however, use an additional L or R KH310, for center. I'd go for the KH120for surrounds. As for Atmos... anything goes IME. .I don't understand something. In shops, I see model Left and Right, what about center?
What do You think, is KH80 enough for rear, back and Atmos speakers, or better buy KH120?
