Sound absorption panels for unside stand??

Ya, Dynamat adds MASS to whatever its attached to, makes that harder to vibrate with sound waves. I am looking for Absorbing. Like the eggcrate type foam that you see in anechoic chambers used for sound measuring.

The egg crate type foam helps with reduction Hi frequency sound waves reflecting off of surfaces (echo)and thats why its so good for sound measuring rooms,but as its a lightweight open cell foam it wont do much for the reduction of sound waves transmitting Through the surfaces of the stand itself. Thats why i would like to try a few different materials, in layers as this is the best method for reducing sound. I have seen a few products that i believe that will work well. I just cant remember the brand names or where to get them here in Vancouver i know they are available as i see them on allot of different job sites. So ill make some inquiries when I go to work on Monday.
