Here is my current listening room: Subpar diffusor behind the speakers Subpar absorber at side wall Speaker placement: Slightly angled up to avoid table (which I am fricking keeping) Toed inward slightly, even at the listening position. The intersection of the drivers would be slightly in front of me. This helps with center image, wider sweetspot, and avoids side walls as much as possible. Positioned from the back wall just to give me the right amount of bass / lower mids. More bass if pushed in more to the walls. Less bass if out. I will probably DIY some absorb panels to go to the left and right of the window, then I am done. Or maybe I won't bother. I don't let room treatments get in the way of musical enjoyment. It is a live sounding room and why I left the "BBC curve" in the frequency response.
