I built five 2 x 4 foot quadratic diffusors for my front wall. I bought the plan from Acoustic Fields. Check out their website they offer a lot of good information. They really added depth, width and clarity to the soundstage. It was a lot of work but well worth it.

I "think" im in need of some sort of diffusing on front wall of small listening room...I would be really interested to hear some experiences of some that have been through it...don't think I need an absorber type...as I have some bass traps in lower corner...just lacking clarity of sound stage...diffusor?
