They are very similar is dimensions to the Wilson Sasha.
One thing I found about the Sasha is how easily they integrated into my current 14x17 listening room. They were a breeze to setup and do not couple nearly as bad as some of the Sonus Fabers and Dynaudio I've had in the same room. If the Magico are similarly forgiving, that would be great and should be no problem for a larger 16x26 room.
