Has anyone tried these products?

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.

Panels such as these have been engineeered for maximum sound absorption per unit of thickness. Their specifications are credible.

Nobody is going to plaster these panels on all of their wall space. They are intended to reduce reflections in a live sounding room, especially in a home theater setup where you want the speaker locations to provide the imaging.

The nice thing about this product is that it is cheap and you can experiment with it without spending a huge amount of money. I am about ready to move into our new house that has a dedicated listening room and I intend to use this exact product. I have some Japanese banners that I am going to use as covering and the flexibiliity of these panels is a great asset.

Deadening a highly reflective room can dramatically improve the imaging of a two channel system. Unless you want to spend big bucks on a professional evaluation, design, and installation, the Audimute panels are a great option.
