Take the core diffusors units and put them at the first reflecting points on the side walls.
To find the FRP place a mirror on the right side wall, sit down in your listening chair,
when you see the right speaker,
that's the place for the Diffusor.
next do the same for the left.
When you hear the improvement take it up a step further by diffusing the left speakers reflection off the right wall find this by placing the mirror on the right wall, when you see the left speaker that's where you place the next diffusor and repeat for the other side.
