Yes and in the words of many people: to D'Appolito or to not D'Appolito that is the question.

The main reason most people don't use three identical speakers is because its impractical and once you leave the plane of the mains, alot of acoustical complications kick in. Joseph D'Appolito got it right with his asymetrical MTM configuration as the best solution to this problem. Fleishman's views are very out of date.
