I think I'd avoid the ML's for this application. Although they do meet your requirements, I doubt they'll be very good in your room: it's too small, especially if you have to put office furniture in it. MLs just about have to be 3-4 feet from the back wall, and in a 11x12 space that's a major disruption. (I am a big ML fan and my main system is fully ML, it's not that I don't like them.)
My first thought was a used set of Magnepan 3.6Rs, but they will have a lof of the same problems as MLs, and they are even bigger.
