My MG12's are only 63 inches apart (tweeters on outsides) but 7 feet from the wall behind them, my room is 12.5 feet by 15 feet by 8 foot ceiling (short wall placement) and I ABSOLUTELY LOVE THEM.
But my listening sweet spot is only one cushy chair wide.
Chair is about 18 inches from back wall.
I did find that a power amp with SERIOUS quality and power made a HUGE improvement even at low listening levels. The maggie MG12's are not the last word in bass slam, but they seem to be really there for ability to transduce high end rythym and harmonies provided you have the source components that can deliver those qualitys.
