I feel your pain. Getting my room to work with a minimum of treatment has been quite a challenge! Mine is 18 X 31 with open beam ceiling (12' peak), spanish tile floors, front wall 80% floor to ceiling glass, back wall is all glass.
After a revolving door of efficient speakers and components I finally have a magical system!
I have settled into Magnepan 3.5Rs (awesome midrange when bamped! 3.6Rs would be a great choice, to) My system is fully balanced and biamped(critical). Wyred 4 Sound 250 SX on the mids PS Audio GCA 250 moded by Underwood for the ribbons, a Behringer CX3410 active cross over and a Raysonic 168 with cryoed NOS tubs. Tube out eliminates preamp. The bass is supplemented with a powered SVS Ultra subwoofer.
PS Audio Premier Power Plant
Cable choices will make or break the natural sound, especially in lively rooms. My preference is Clear Day Solid Core Silver cables (shotgun) Morrow power cords, DH Labs/PS Audio/Morrow silver interconnects.
Consider a thick artistic large area rug in front of the system, matching or comlimentary smaller ones on front wall.
