Has anyone tried these products?

Looks promising....thanks for posting !

Never saw this Jim, but I would be a bit weary if indeed it absorbs 95% of the sound as they claim. It would seriously deaden the room imo. 

Agreed with @baylinor . You want more of an acoustic diffusion rather than just absorption. A lot of people get these panels for big noisy rooms or churches or attic Studios or things like that. There are several purveyors of good two feet by 4 ft acoustic panels out there. You can also try this:

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.

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.

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.

@8th-note 

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.

I suggest getting a few of their smaller panels. They are light enough that you can hang them with some strong double-sided tape and experiment by moving them around. 

While on absorption...what do you guys think about adding absorption to enable higher volumes?  I've had a lot of success making sure parallel surfaces are very well treated but that's about it with carpet and heavy curtains.  I can go super loud but wonder about the dynamics of the other characteristics of sound.  They can get lost a bit when getting really loud.  Thoughts?  These panels would seem to be good for this application.

unless you have a reference mic and Rev (free room analysis software) then just placing an absorber on the wall isn't going to do what you think its going to do. there is no such thing as 95 % dampening unless its 24" thick foam or glass battens or an open window. all dampening materials have only a select frequency band that they absorb, so what you will end up having is a room dampen too greatly in one band of frequencies while another band wont have enough and what you end up having is a bad sounding room that no eq is going to fix. 

One way to avoid this besides using forementioned reference mic and software is to build a book shelf like phase diffuser, which like the names says is a diffuser that splits the frequencies up and refracts them at different angles such that standing nodes are well dispersed. 

but considering REV is free and these days reference mics are quite cheap - especially for room analysis, it would be a good way to go. 

a book shelf works very well as a phase diffuser - plus it adds a bit of elegant snobbery, especially if the books look intelligent (you don't have to read them btw) but used books are cheaper than phase diffusers by a far amount.

Floyd Toole of NRC fame ( he is now with Harman) was the one that suggested this to me while building my studio many years ago, while at a AES meeting in Toronto.

Having phase diffusers will not alter the tone of the room but will reduce or eliminate nasty resonate room nodes. The only area they are not so good are low frequency (150 hz or below) where open windows and bass traps are your best friends. Again if you spent $5k on your hifi equipment, at least spend $500 (at the most) on a reference microphone and REV or similar software
