I just built 2 2x4 Bass Traps loaded with 4" of roxul to augment what I already have in the studio. I had originally planned to mount them at a 45 degree angle at the ceiling/wall corner behind the desk and move the clouds that are currently mounted about 18" from the wall to a position parallel to the ceiling directly above the desk. But now I'm thinking that I should put them on stands and place them horizontally behind the monitors (partially blocking the window) and leave the clouds where they are. The wall opposite the desk is covered with 3 2X4 panels with 2" roxul. The back of the desk is also about 18" from the wall. I thought it might be cool to see what suggestions other members of this discussion group might have about the placement for my new traps. All polite opinions are eagerly awaited.
