How much room for Magnepan 1.6qr?

I'm setting up a secondary system for my office. I've got a Bryston amp and I've heard they pair very well with Maggies. I've never owned planars, and I wondered how much room I need. The room is about 10 by 12. I sit about 5 feet from the back wall, off center in the room, but centered between the current speakers, which are only about 5 feet apart from each other and about a foot off the front wall. I can bring them A LITTLE bit into the room, but not hugely. Are Magnepans appropriate for this set up? Thanks. -Dave
