Front or Back wall diffusers

Without more info, you only will receive useless advice. Need to know speaker position, listening position, etc.

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.

Also, about 6 years ago, when drawing the original plans for the house of stereo, GIK told me that the front wall should be addressed last if at all. Just saying.

That's interesting. After I fully treated my room I noticed that my music wasn't very lively and imaging wasn't very good. I began to remove panels from the front wall and the more space on the wall, the better it sounded. Now I have no treatments on my front wall and music sounds better than I could have hoped for. Listening to large scale classical I'm experiencing a wide 3D soundstage with concert hall ambience.
