Question: Sound Treatment behind the Listener?

Thanks,

I'm not sure how many of the Alpha 6a's would need to be acquired. 3 of them with shipping is $763.

I use Rockwool @ 35Kg per M3 floor to ceiling in height as a Absorption Room Corner conditioners. Directly behind and spanning between the Speakers I use a Diffusion Panel.

Each Side Wall has a diffusion pane.

The Rear Wall has a Aborption and Diffusion Panel set at a height of the listeners ears.

The sound is managed in a manner that has improved attraction with these measures in place.

Would it be identified as a accurate treatment using tools the can measure room modes is an unknown for me. 

Thanks Vinyl Shadow for the info.

I'm getting some advice from GIK but also just started a dialogue with Jeff at HD Acoustics who I found when searching here. It won't be free but it will (should?) be unbiased and sounds like he knows what he is talking about....because I don't w/ acoustic treatment on the rear wall.

I have found the Acoustic Insider channel on YouTube to be a good source of information around treating your room.  He mostly discusses treatment for small home studios, but the theory still applies to a listening room.  

As far as I can tell, he's not selling anything.  He does reference a document you can download, and I have no idea if he charges for it or if that is a gateway to purchase other stuff, but I've never looked into that.

Thank you, I will check out those sites.

It sounds like GIK wants me to get 6 of the Alpha 6's. I'm not sure if $1500 would better the sound that I have now with the cd rack.

I may try some convoluted foam I have behind me first just to see if absorption is where I wanna go.
