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 ?

Hi Blueskies,

Have you solved, or at leat diagnosed, the problem with excessive brightness?
I have added 2 diffusion panels and the doors behind the seating area. They have helped but I continue to move my speakers around and am still testing various positions. This is difficult to do by oneself. My music club will be here next week so 4 other pairs of ears is always helpful.
