Sound diffusion panels--do they reduce brightness?

My listening room is still a little too bright
The doors behind the seating area have 2 absorbing panels. It has been suggested that adding 2 diffusion panels in this area of first reflections will cure the brightness. Does anyone have experience with these diffusion panels ?

Blueskiespbd - have you an update on your "brightness" problem?

I added a QRD diffuser to the side wall to treat the 1st reflection from the main speaker on the opposite side of the room which reduced a bit of HF glare while improving musical details. So, using a miror I found the spot on the left wall that is the 1st reflective spot of the right main speaker and vice versa for the other side wall, and placed a 2ft wide diffuser there at ear level. Worked well as would a thick absorbing panel. You might try it.

I added 2 RPG Diffusers behind the listening area and 2 absorption panels there also. The room is now tame and sounding most excellent.
