Looks like the inside of an alien craft, perhaps they‘ve been studying humans a long time and decided a guitar motif reminded them of their favorite snacks (humans)!
The argument for/against room treatment
- Thread starter MadFloyd
- Start date
If i fell asleep in a listening room with Wadax gear surrounded by those diffusers, i would definitely think i had been kidnapped by a Klingon Byrd Of Prey spaceship upon waking up !I don't know, it could double as a climbing wall
LOL ! I wrote this before seeing Bobvins post ! 
Thanks Cal ... I did read that ...I think the picture is worth a thousand fractal fibonacci golden rectangles
I'm not doubting they used those geometries as it is spooky how the maths throws them up in so many fields but the reflective pattern away from the median plane ( thats the horizontal listening zone in the room ) would be the key to this IMO
I have seen acoustic engineers set up the paremeters for this sort of device ( less complicated) in excel and run the program overnight to optimize it .. its very cool and it does what it says on the can

That is just a horrible comment. I had a genuine scare you might have been serious the company I'm thinking of branched out. Horrible comment.
My bet is on one too many viewings of "Heavy Metal" back in the day.
Sound control is even more important inside a spacecraft, of course!
That practicality is probably Giger's primary inspiration... https://www.hrgigermuseum.com/
In fact, DHDI claims that as long as the trade secret angles/patterns of non-parallel surfaces are maintained the Zero Reflection technology can be incorporated in something as thin as window curtains:
ZR QuanTex
Thin as velvet and elegant as victorian drapes, custom ZR Fabrics are lush, beautiful and imbued with the ability to make sound vanish. The latest evolution in Quantum Acoustics is concealed within any beautiful drape, curtain or textile that your architect or interior designer can envision...

If they don't absorb, diffuse or trap, what DO they do?
Peter, that is so helpful, thank you. I would have guessed you would have said something like "they make money for the manufacturer"
They "deconstruct"the sound waves at the level of the air molecule (sound rides on air) before reflections can form by bouncing the air off of thousands of tiny non-parallel surfaces (of a specific angle and pattern) per sf of panel. Explanations, reviews, client lists, etc. appear repeatedly earlier in this thread and in my thread "Trying the ZR Acoustics Panels" where I document my experiences testing them head to head against conventional acoustical panels, and provide photos of my ultimate deployment of them in my listening room. At the risk of repeating myself, the client list speaks volumes:
Naturally people steeped in traditional acoustics and/or with no experience with the ZR panels are skeptical of what appears to me to be a disruptive technology.

I am sure they do work but not by the method stated or to the extent. They are very shallow, not too offensive looking and easy to install so people like them.They "deconstruct"the sound waves at the level of the air molecule (sound rides on air) before reflections can form by bouncing the air off of thousands of tiny non-parallel surfaces (of a specific angle and pattern) per sf of panel.

As far as I can see there are no measurements backing up the claims. I did see a post that referred to a patent application... I think ? that stated a range somewhere around 250 to 1500 Hz which is very good for the depth so it may well be they have generated a reflection pattern that causes primarily sideways reflection or cancellation or fuzzed it up in some clever way that makes it appear deeper to the sound hitting it so good on them. There are well known ways to do these things.
I think it is the marketing blurb that everyone objects to - it would not be the first product in audio that makes very complicated claims about a new breakthrough that dramatically overstates the case but then show no measurements to back it up. Unlike other areas such as cables this is easily measurable.
I don't think you would get so much eyerolling if you just said you really liked how they worked and avoided repeating the manufacturers claims.
My view on this subject is that "room treatments" are not how we should think about the room, rather it should be acoustic design of the room where all the sound issues likely to arise are considered and dealt with with the minimum of devices that are optimal for the purpose .... this can include furniture, artwork (mount off wall and locate acoustic blanket behind), drapes etc
Banquette seating can become a bass trap, peter A's timber louvres used as diffusers - it goes on and on - if you think about what you are trying to solve use a functional piece of furniture to do the job and where that cant be done you move into the dedicated panels that are specifically designed for the issue identified - it always pains me to see panels all over the place like they were vomited into the room
My own belief is that if you have a calm elegant room that follows these principles you achieve a visually calm and acoustical logical space that enhances your appreciation of the music - its like the visual and aural flow are in balance and you relax more and focus on music... but of course I might be dreaming
I understand from studies in concert halls that the better your view of performers the betters it sounds regardless of the acoustics ... same with quality of airconditioning - it all allows you to relax and focus on the music - less fatigue etc.
Thats why I would never use ZR panels regardless of how well they worked - the psychedelic era is well gone for me

I personally love the look of the wood panels; I'd hang them just for that alone.
The manufacturer's explanation makes sense to me. I don't have any basis for disbelieveing it. I've already talked at great length about how they actually sound - as opposed to speculating.I am sure they do work but not by the method stated or to the extent. They are very shallow, not too offensive looking and easy to install so people like them.
