Krunch, yes that was an interesting discussion, both as to an MTM center speaker and none at all, employing a "phantom" center. These options have been discussed here several times in the past, and it has been pointed out that others, such as Tom Nousaine, have described essentially the same difficulties. It should be remembered that the MTM arrangement devised by Dr. D'Appolito was specifically intended to have broad horizontal dispersion when positioned vertically and to narrow vertical dispersion to help minimize problems with floor and ceiling bounce. When positioned horizontally the opposite result occurs.
