Thanks in advance for taking a look at this.
I've made some improvements to my components and swapped speakers and things are sounding so much better. But, I have a horrible room and looking for advice on tweaking it.
First, based on the features of the room and layout, I cannot think of a better way to arrange the listening configuration. Open to opinions on that but WAF and other things that are not pictured (windows, HVAC venting on the ceiling) also limit the possibilities somewhat. I know the placement of my sub is quite suboptimal.
It is a basement, finished w drywall, fully carpeted with "popcorn" ceiling about 8 ft tall. I have done some sound treatments:
-insulated the HVAC room walls and doors with various things(pink stuff, carpet, big peices of plywood and drywall). This dramatically reduced the background noise
-soundproofing in an adjacent unfinished store room to block sound to the living room directly above it (wife naps there. nap time = hi fi time for me.)
-made 2 1.5x1.5ft panels using 3.5in R14 wrapped in felt. Affixed to the ceiling half distance between where my ears typically are and the book shelf speakers. Did this to fight first order reflections.
My biggest issues with the sound (I think) are around imaging and the general presence of that wall between the speakers. I swear I can hear that wall. There is imaging but most of the sound appears to come distinctively from one speaker or the other.
What I am really most curious about is options for room treatments such as diffusers, absorbers etc. I was wondering if a diffuser of wood slats in various widths/angles on the front wall or behind me could help? Not a lot of space to work with as the space is also kind of a hallway.
I attached a diagram (scale is approximate!) and a picture to help you visualize the space.
If it helps here is my equipment.
