Who makes those diffusers? Have you ever measured your room with REW or something similar? Just curious how it looks.........
Just got back from Transformers 3.
I never did do official sweeps with the RS meter. I loaned out my test disc so cannot do it now. I'm sure it has the expected modes but the bass is well trapped and the diffusion has made the sound more 3 dimensional.
The room has 6 different diffusor brands:
Gik D1's sides, back, door
Gik Gridfusors directly behind seat
Real Traps Near diffusors behinds the speakers
RPG diffusors ceiling
Auralex T'fusors ceiling
DIY prime 53's side walls
Plenty of 703 in the room in the corners, on the ceiling, in the moveable boxes under the side wall diffusors and back corners. The side wall diffusors and ceiling diffusors made the most impact in my opinion.
