I have experience with M2OW and M5OW. There is no need to toe in either. They provide great imaging and if they are 3 feet or more away from side-walls, they will provide a wide soundstage right out to the room boundaries. With you sitting 12 feet away, at louder volumes I expect the soundstage to wrap around the sides.
