Just load up the room with a couple dozen 5’ - 6’ artificial Ficus trees. They are cheap and very effective. Use along the walls, between the speakers and alongside and behind the listening position.
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.
