"The room can totally wreck, or make, a system"

Too bad all speakers aren't as easy as Ohm. You tell them the room volume and they give you the appropriate speaker.

I'd rather start with room friendly speakers. From what I hear, 1st order like Thiel are the worst. Even my B & W with steep x-over got bad room reflections when volume was turned up. Sound became confused and muddled.

Research proved that in a live musical environment, approximately 30% of what we hear is direct sound while 70% is reflected from walls, ceilings and floors and only reaches our ears a few milliseconds after the direct sound. The human brain uses direct sound for identification and to calculate location, but uses reflected sound to determine musicality and spaciousness, as well as direction.
