Please list your listening room(s) dimensions (width x length x height).
And if you have any acoustic treatments...list those too, and approximately where they're placed.
For instance:
My listening room is 15.5 feet x 39.5 feet x 9 feet (~4.7 x 12 x 2.7 metres). I have two bass traps in the front corners behind the front loudspeakers - 2' x 4' x 4" thick. Elsewhere around the front three loudspeakers I have 20-24 Sonofiber squares on the front wall and on the side walls to absorb early midrange reflections in order to improve imaging.
