Paul, I have first generation Homage's in a rectangular but asymetrically dimensioned room equivalent to 20' X 18' X 12' (ceiling height). My opinion is the room just barely handles them at normal listening levels. I do have some real acoustical challenges (back wall virtually all glass, one side wall rock, other side wall partial 9' celiing). It is hard to "lose" these speakers visually (not that I want to), but I have finally (after a few years) gotten them tweaked to disappear sonically. All-in-all I wouldn't part with them for the world, and certainly not for Anniversario's. I know they were supposed to be an upgrade, but not to my ears. Be sure to audition both. Good luck.
