You will need absorbers and diffusers for certain. Just look at my house of stereo. Too much work involved to put it in a post and it's all room dependent anyway. Keep at it, you will make mistakes, persevere and you will be glad you did.
Absorption, Diffusion or a combination of it all?
Looking to add more acoustic treatment on the wall behind the speakers. Currently using GIK absorption panels (242).
Planning to add two more panels that would hang pretty much directly behind the speakers on the upper part of the wall (higher quality image on my system page).
Any benefit going with diffusors?
Thanks!!!
