Anticipating counterarguments, rooms are not that important. Sure, you can spend hours with a SPL meter and glue foam/fabric traps all over the room and get anal about things. But a typical placement in a triangle with your listening seat is usually fine. I adjusted the distance apart, toe-in and distance from wall with my speakers and they sound pretty good. I'm sure a dedicated listening room would be better, but a little work has them sounding better than the HD-800.
What. I don't know you completely understand sound treatment, and especially bass traps. It's just not about glueing random foam traps somewhere..
I disagree with this statement, and say that the room is far more important than the speakers that are in the room.
