More on this project...
Since this is a home theater I decided to use diffusers over the listening area, even close to the listener's position (I am aware of the "bad" sound of diffusers near the listener bla bla bla... don't care)
This is to preserve some live acoustics characteristics of the place and not turn the room into a dead space. RT 60 will be around 0.2 to 0.4 s at mid frequencies, good LEF above 20 % for spaciousness with first reflections being diffused rather than absorbed.
