Finally, I should have mentioned that the room has hardwood floors. Despite that, I wouldn’t characterize the room as “live” nor “dead”.



I too have hardwood floors. No rug, and very little on the walls. My M60's still don't sound "bright". A recent guest who stopped by to give the Axioms a demo even commented on it. He had said that he'd heard that Axioms were bright. He also disagreed. Hardwood floors won't be a problem.
