Room treatments behind or between speakers?

Thanks guys. I have already treated my first reflection points on the sidewalls and it made a big difference. I have Realtraps bass traps too. Now I am just wondering about front wall absorption, directly behind speaker, in between speaker, or both?

I put mine behind the speakers. Why? Because I had two of them.

But seriously, I understand absorption directly behind and diffusion between. I can't remember where I read that but the explanation made sense at the time.

Tboooe,
If you have already purchased the room treatments, then I think you should try it out in both the places:
1. between the speakers on the wall behind
2. directly behind the speakers on the wall behind

Chances are you will most likely choose option 1. This is what "locked" down the center image in my case. My room being small, the center of the wall behind the speakers was reflecting a hell lot of sound. Once I put the absorption panels in there the images became very stable.

So indirectly, I guess, the answer is - it depends a lot on your room. Good luck!

What are you trying to deal with, what is bothering you when you listen.

Thanks Milpai. I look at your system page a lot. I love the simplicity of it. If you think your room is small you will think mine is tiny. It's only 9x10 but the rear is open to my family room.

Samhar, I am not sure what I am trying the achieve. I don't know what I don't know right? :). Like all audiophiles I am always looking to improve my system.
