Hi Kevin,
It's great that you are designing a room from scratch! If you use dipoles, you may want to consider diffusion behind them. I've spent a good amount of time with dipoles in a room 14.5x18x11 (slanted ceiling from 8 to 14 feet), and you will need treatment. Maggies and other dipoles don't have a lot of side reflection, but plan to bring them out into the room a decent distance (e.g. 5 feet). Even more specifically, I'm writing about your choice of Maggie 20.1's. They are absolutely great speakers... a very natural sound. I've had them in my room. I've upgraded them with Mye stands, biamping with an excellent custom Xover, quite a few different amps... and my overall opinion is that your room may be too small for the 20.1's. They really need some room to breath. And while I found them to be more dynamic and spunky than my Quad 988's, they never really reached their potential in my room. I've finally gone over (back) to the other side of conventional (cone) speakers and am using Avalon Indras, which I am enjoying immensely. Do remember, it takes a lot to get the most out of Maggie 20.1's. Perhaps you might want to entertain the idea of a pair of Emerald Physics - which may fit the scale better. In any case, good luck and let us know how it goes.
