PLEASE ADVISE. My question has to do with the close quarters in general--whether just 5-7 feet from an M80 is less than optimal no matter what the volume (probably true for an M60 as well, but I imagine it could be a non-starter for the M80). I went for the 600 sub because this room is open at the left side. It's a house where the kitchen eating area and den span the length of, well, three rooms. However, it's not a very deep den. Even the optimal watching/listening position on the couch at the back wall is just 10 feet from the front speakers and TV. Thanks everyone.
