i have the m80s, and unless your able to get a good 12-15 feet away from them,i really dont think they would be a good choice,dont get me wrong i love the m80s but they seem to need their space....using 4 of them for surrounds in a 20x20 room will definitly blow you away volumewise,but,you probbably wont get seamless sound experience your looking for........just my oppinion ....... ron
