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.
It looks like you are discovering one of the most annoying "secrets" about audio. It can literally take years to discover the ideal placement of speakers. Results are quite unpredictable, and shockingly small movement can have BIG sonic consequences.

When using the "Sumiko Method," sometimes moving the speaker an inch in one direction will significantly alter the bass balance of the speaker. This is both frustrating and positive (gives one hope of finding a really good location).

just keep plugging away.
