When choosing a dedicated listening room, try to avoid rooms with equal distance on all four sides, or rooms with length exactly twice as long as width. Geometry as such will increase the echoing effect and increase coloration.
If possible, place seating in between the two walls where rear speakers are mounted. The closer speakers are to corners of wall, ceiling and floor, the larger volume of bass will be heard. However, sometimes bass can be overloaded.
