After hearing QS4's as mains before my M80's arrived I wondered about the potential of using them as dual centers, one above one below the screen.
Then the thought went off on a bit of a tangent.
Lets just say a guy could afford QS4's or QS8's for each position...
I don't know what I'm thinking. I do want to hear your pro's con's do's and don'ts...
