You could also try toe-in the speakers pointed directly at your ears and near field listening. You'll hear more speaker and less room.
Room treatment
My listening room sounds overly dampened, and I want to look at options for making the sound brighter. The room is 4 meters by 7 meters by 2.75 meters. Two walls are mostly covered with bookcases, and two walls are partially covered by curtained windows. The floor has wall-to-wall carpet. What should I consider?
