@amir_asr , I walked the walk, my "nodes" are fine as you can see in my profile. As for yours, IDK what you are teaching but apparently you still have a lot to learn.
I suggest you pick up a copy of Geddes book "Premium Home Theater Design and Construction", you don’t even have a decent room for your gear yet from that pic @prof shared.
As for Toole, come join us in the FR thread, I have some stuff posted that may help you get your FR straightened out, that graph @prof posted of your room looked a little sloppy, you are abusing the DSP, it isn't designed for a total makeover.
