What type of diffuser goes on the back wall?
 

What type of diffuser goes on the back wall? In other words, what frequencies will I build for, low to high?

http://www.mh-audio.nl/DiffusorCalculator.asp

The front wall is 3" rockwool, sides will be with rockwool as well as ceiling. 1/2 of the back wall is 3" rockwool.

Dimensions of room, 8 ' ceiling, 12 feet wide, 20' in depth.

Thanks!

What is the room going to be used for? HT? 2 channel? Studio? I assume HT?

Diffuser will go at the top of the garage door.

Up there it's more for flutter echo so I would build for higher frequencies.

What's considered higher frequencies?

Also, would it be a better idea to move the absorption panel to the top and put the diffuser at the 2/3rd's spot? If so, would I build diffuser for different frequencies?

How far behind my AT screen should my speakers be? 2"? 6"?

Are you leaving the garage door as functional? We stuffed ours with insulation, and screwed it together to stop it from vibrating. We also built a fake wall up in front of it and stuffed it with insulation.

Yes, it will be functional.

What do you consider "higher" frequencies? Is it 500 to 20K?
