It's obviously room dependent. In mine diffusers/absorbers on back wall and diffusers only on rear of both sidewalls. Also diffusers at first reflection points on sidewalls and absorbers right next to them on second reflection points. Plus diffusers on ceiling between listening chair and speakers. Hardly any diffusing on front wall specially since speakers are 54" from front wall. I believe many audiophiles put diffusers on front wall because they like to look at it. To each his own. I go strictly for sound. You questioning the matter is smart. You can see most of my acoustic setup on my house of stereo system. Enjoy the journey.
Front or Back wall diffusers
Front or back wall diffusers, I have a 14' x 24' x 8' stereo audio room with Wilson Sasha DAW speakers. I want to know which wall to place it on. I have seen many photos with diffusers on the front wall, this is the most recommended, but I have doubts. Please some suggestions.
