Has anyone tried these products?

I could not find any technical information at the Audimute website.  

I haven’t emailed them yet to get any information and being only 1.5” thick, I’m guessing the absorption is limited. I also agree with @baylinor , that there’s probably no way they can absorb 95% of the sound.

I’ll try to send them an email and see what they say.

@simao 

Thanks for the link,

but I wonder how effective they would be at only .38” thick?

@curiousjim  that's the thickness of the backing. The slats themselves are an inch thick.

I have a number of Audimute panels throughout my listening room along with a couple of GIK diffusers and they were a big help.  I have the fabric covered 2" panels, not the same as those you are looking at. 

Where is the wall in your listening space?  Front, side, back?  What issues are you experiencing that you're trying to tame?  Slap echo, side reflections, etc.  Make sure you get the right tool.  Absorbtion can help or hurt.
