Mary, unless you move your listening position closer your M60s should be separated by at least 10 feet and toed-in slightly so that the tweeters point at your ears. Another basic positioning rule is that the distance from the woofer cones to the floor and each of the two nearest walls should be unequal. It should be okay to have one of those three distances very short, but experiment.
