I’ll tell ya what works for me:
My room is 19 x 29. The ceiling has a gable on one side and dormers on the other. The gable roof is 12 ft at the apex, 3 ft at either wall.
The ceiling is covered with 17” of rock wool. The walls have 6”. NO SHEET ROCK: I covered the insulation with fire resistant burlap.
My 3,000 book snd 6,000 LP library line some of the walls.
The floors are plank hardwood. I cover the floors almost completely with throw rugs. Only four small windows: blankets cover the windows in the dormers during listening.
This has given me a fairly dead, semi-anechoic room. The acoustics are superb. Most people notice immediately upon entering the room the difference in how their voice sounds.
The room was added to my system three years ago. My system has otherwise been the same for 36 years. The room lifted the overall quality to a place where I don’t feel any need to be looking for a anything else to make it better. I sit back and enjoy the music.
My room was designed by a Cooper Union/Harvard trained architect (and friend) who came up with this concept with a classmate who is a “sound scientist/architect”.
The Square shape of your room is a problem. I would put a wall in to create a 4.5 ft wide room along the length, and put your equipment in there, and your record library in there (yes, I’ve made an assumption there, but whatever).
