A pragmatic factor is that 8" deep absorbers are cheaper than 2 or 4" units because the absorbing material is cheaper!
GIK sells what people buy. They provide treatment advice also. People also treat performance spaces and depending on the desired result, such absorbers may exactly what is desired. If you want more information about that then post the question separately.
You did not answer my question about where you got that information.
Welcome to the world of acoustics. Good luck!

Ah, thank you much for clarifying that for me. I understand now. I guess there's no need for 2 inch panels for me since I'm not concerned with real estate.
I plan on doing:
2 vertical soffits (4ft, 17x17" each) in the 4 power corners = 8 soffits total
2 soffits horizontally in the crease where wall and ceiling meets = 8 soffits
4 inch panels on front, back, side walls, and ceiling cloud
For the panels, I know it's best to have air gaps behind then so it's not flush against the wall, but would having them flush actually worsen it's effect? I dont see why it would hurt the sound, it just wont be as effective, right?
