I own (and like) Cremonas, but you might want to think about speakers with a more limited dispersion pattern. If you're willing to move the speakers out into the room when listening (and back when you're done) a narrow planar (Final, Martin-Logan, etc) might do the trick. If you're unwilling to schlep, you might consider a horn or horn/subwoofer set-up. Either way, you'll be pouring less off axis energy into the side walls.
Good luck.
