OK guys, I'm ready to work on sound treatment. I've been doing some research and it looks like some people prefer absorbtion only, some prefer diffusion only, and some say you need both.
I am in an L shaped room. Speakers are about10ft away. I've added some padding to the wall behind the couch because I sit right against the back wall. The rest of the back wall is bare and the front wall is also bare.
Should diffusion panels be on the rear and absorbtion on the front wall?
