Thanks for the kind words. I don’t have a youtube channel, however the video that helped me a lot was the series on acoustics that had Anthony Grimmani as a guest. He was kind enough to correspond by e-mail and really helped me with implementing his "acoustic recipe". The recipe was a good starting point and then you roll up your sleeves and start hanging products. Auralex was the vendor I chose and they were great to work with. I used the Dolby specs for most of my speaker placement. For the size of my room I divided up the room using the fibonacci ratios for seating and treatment placement.
The MLP is at the 50% point exactly between my front and back wall so those speakers are equidistant from the MLP. Front speakers with tweeters at ear level, the bottom of the screen starts at eye level.
If you look at my ceiling you’ll see absorption in the front third of the room, at the mid point I have those diffusors, "geofusors" based on the geodesic dome, that are filled with polyfil so they double as bass traps. At the two thirds point between front and back wall I have my surround and top middle surround speakers. Then 75% of the distance from the front wall I have my PJ and the "acoustic cloud" hanging which is a 3D diffusor. The second row of seating is just below it.
The panel placement on the walls are asymmetrical. If I have an absorber on one side wall (yin) it is mirrored by a diffusor on the opposite wall (yang). Then each side wall is interleafed (absorption, diffusion, absorption, etc)
The panels are also placed at the same fib ratios, 1/3 from the front wall, 50%, 66% and 75%. This worked for me because of the length of my room, for a longer room you would need to add more rows of seating, have a bigger screen, etc.
