Has anyone tried these products?

@simao 

Thanks for the link,

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

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.

Hey Greg,

 I have a second system in “Bonus” room in the system. With the exception of a couple of CD racks and my listening chair, there’s not much else in the room to defuse or absorb the sound. These looked like an inexpensive way to cover some of the wall space with the benefit  of helping taming the room.

Thanks for the reply.

The room has two concrete walls and does have carpet and pad, but it’s on a concrete floor and that’s it. I was hoping that for just a few hundred dollars, I could calm it down a bit.
