Dark Grey convuluted foam

Thanks for the responses.
The stuff from Foam by mail looks like the stuff I was thinking of.
I dont know if I need it as much as I thought it would look cool behind my speakers.
I also thought the idea was to have a dead end behind the speakers and a live end behind the listener.
Anyway, now I am confused,by some of the comments, if putting this stuff on the wall behind the speakers will deadin the dynamics.

Ryder, Thanks for the response.
I do not have a problem with high frequency at all.
I was thinking of soundstage depth.
With my Big Sony in between the speakers, I am sure that limits my options.
Covering the TV while listening to music is ok, but, I also watch Sports while listening to music.

I am using ASC 16" Round Bass Traps in the Corners and on the side walls I have ASC products on the first and second reflection points.
Behind my Sony LCD is a half moon ASC trap and above it is an Echo Buster on the wall.

I was seriously thinking of treating the entire wall behind the speakers to create a dead zone .
I have read that that is desirous along with the area behind the listener as a active zone.
So, behind me is my thousands of CD's on racks providing reflection surfaces.

Chadnliz, yes thanks. It looks like it only comes in the color natural(whatever that is)

Timrhu, good tip. Thanks everyone .
I just looked at the web site and it stinks!
I mean, I was not able to find anything as to the price of the products. I hate that!
The room calculator was nothing more than giving the web site my name,home adress, and email. The calculator then would not work !
Also, I could not find any mention of the Roominator kits.

How did you guys know what to order?
Must I find some dealer in order to find out these things?

Thanks!
