All of it ! alternate absorption and diffusion , use absorption at the first reflection points.
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!!!
