Request for assistance please room treatment

I do have it treated now, but I don't think it's correct. I need to treat it properly. I've tried a multitude of different positions, absorption, diffusion, trapping, etc. and my walls are starting to look like swiss cheese. I'm at the point now where I need to strip the room, putty, sand, and paint. But when I re-install the room treatments, they have to go in the correct position the first time. This is where your assistance comes in. I've tried many different web sites and so on, but it all seems best guess. I'm hoping to lean upon your "experience".
My room is 22'long, 11'wide, and 7'4" high, and is in a finished concrete basement. I look forward to reading your suggestions.
Thank You.

I am also wondering what exactly your room treatments are trying to fix? There are some holy books out there now. I forget the title but it's something like "Get Better Sound Now" ..??? not sure but you see it mentioned all the time with his advice to get your components out from between your speakers. Did you try to search for old threads on the topic, that may prove useful.

FWIW, while I too would like to hear what you think can be changed or improved by the use of room treatments, I think that the photos of your set up suggest (to me anyway) that one of your problems may be related to side wall reflections which might just be cured by toeing in your speakers until the axis of your speakers cross in front of the listeners chair.

I might also mentioned that the rooms dimensions could easily cause substantial nodes/nulls which could be avoided to some degree by careful speaker and listening position changes. You might consider getting a SPL meter and a frequency test disc which will help you identify the nulls and nodes which need to be addressed.

It's very easy to overdo room treatment. My system greatly improved and got more alive when I removed most of it. A number of friends had the same experience.

Room acoustics is 90% science and 10% the "black arts". You need to measure your room to understand what is going on and what needs to be addressed. You must take a scientific and pratical approach to treating a room. It takes time with a lot measuring and remeasuring, listening and relistening, the proper treatments with an understanding what they do, trial and error, and a ton of patience.

You haven't stated the problem area with the sonics in your room. Based on your photo, the room is very well damped (maybe over-damped).
BTW, I agree that toeing-in the speakers might make a change for the better.
