most important spot to put first slab of absorptive material

[ardy77]

I currently have an ugly corner desk that turns my equilateral stereo imaging triangle into a diamond!! I heard you should not have your setup in a corner so I am going to be rearranging and moving my setup to a better location...so let's say I'm facing a wall now instead of a corner...where would it typically be most important to put my first slab of absorption/diffusion?? I would think it would be directly behind the monitors against the wooden walls...is this a good place to start? Also, some acoustic foam has the familiar "teeth" cut into it..others look completely flat (and still other look like carpeting wrapped around a peice of wood)...whats better/best?

Thanks =)

Long story - Basically, you *might* want a small amount of foam on the side walls between you and the monitors.

You most definitely will want broadband / bass trapping in the rear corners (that's the 4" thick rockwool/mineral wool/OC703 stuff you normally see wrapped in cloth).

Probably start here - www.realtraps.com and go to the acoustics articles. That will make a lot more sense than I do before my first cup of coffee.
