I have an Axiom 5.0 system (sub is Adire) in a room that is so "hard" (wood floors, walls, windows all pretty much bare) as to be almost puritanically Scandinavian. I have not found the Axioms to be too "bright" (by which I understand annoying in the treble range) at all. On the contrary, the sound is quite neutral. That being said, the system is in the forward half of a "great" (family/kitchen) room, so the sound waves can "escape" the listening area more easily than would be the case in a smaller, more enclosed room.
