Anyone tried using 3 Magnepan MMGs for L-C-R?

Eldartford-
do you use stands to get the maggies off the floor? do you think that a vert. speaker works well for a center? what type of amp do you use? have you ever had a chance to compare the MG12s to the MMGs? Are the MG12s worth twice as much $$?

bigger and smaller room is so relative though. my room is 13'8'' x 11'3'' carpeted and one side is open to a balcony. will i get much more bass with the MG12s vs the MMGs? i will be using a sub and more than likely crossing over at 80Hz.
