I currently have just 2 GIK 242's at the first reflection points but am looking at adding some more treatments to improve the room. I don't have a ton to work with so I am trying to get away with the bare minimum and add more later. I was looking at going with ATS (I have the GIK sold) as they seem to be inexpensive and fairly decent looking. Here is the obstacle I am working with.

As you can see I have about 6" or so from the sidewalls to the outside front edge of the mains (toed in a bit). This obviously creates a less than ideal setup. The other problem I run into is, there is a door beside the right side speaker which makes it tough to place any treatments there should any be required.

I ran the reflections program and here is what it came up with.

1). It shows quite a bit of reflection on the ceiling. Would it be better to use absorption or diffusion up there. I was thinking of placing one row of three 2" squares about 1' apart from each other at the first reflection point.

2) Place acoustic panels to try and cover a large area around the first reflection point. This would consist of two 4x8 ft panels and 1 2x2 foot panel. This might stick out too far based on my room width but I thought it might look cool and the center panel having an air gap would probably help a little with the lower frequencies.

3) Line the whole stage behind the speakers with egg crate foam (lined about 4' up side and rear wall) and place some 3" corner foam for the lower frequencies.

4) Later down the road I could add another row of 3 panels on the ceiling and a couple on the back wall.

All inputs and suggestions are appreciated.
