In this video, we are back once again with Graham and Mike of Music City Acoustics to talk through how to treat a studio space, and this time we're covering diffusion. Studio sound diffusion can be a difficult topic and there is certainly much more to discuss here, but we hope this video not only sheds some light on what kind of diffusion you can use in your studio but also how you can build your own sound diffusion DIY style.

ADAM Audio was founded in March 1999 in Berlin. Since then the company has been developing, manufacturing and distributing loudspeakers in the field of Professional Audio.
The development of the X-ART (eXtended Accelerating Ribbon Technology) tweeter based on the 1960’s invention of the Air Motion Transformer by Oskar Heil was largely responsible for the company’s founding. Producing sound not with a piston-like diaphragm as is done in most of the loudspeakers that are on the market, but using a pleated diaphragm that is capable of moving the air 4 times faster than the folds themselves are moving was the appealing idea behind it all. The achieved results were intriguing and gave ample reason for moving forward.

Of all the searching sound acoustics for all the years, this is the most organized maker I’ve seen. Yes, I’m jealous. I wish I had that factory inside my garage!
I have been looking for easy to build & effective DIY diffuser designs for MONTHS and I have to say, these are probably the easiest, and most cost effective build I have found. My biggest question is, how do they perform?! I'm willing to build some to find out, so we'll see how it goes. Going to start on them today, but wanted to also share a few thoughts for anyone else considering building these.
The DIY design they run through in the video is basically an extremely dumbed down version of how to build these with minimal cutting, minimal labor, and minimal tools. They altered some critical components of the design in order to make it as easy as possible to build yourself. As a builder myself, here are a couple recommendations I would make to anyone willing to put in a little extra effort, and has the tools available:
- Solid wood, especially the common board mentioned in the video, likes to move, bend, twist, etc over time. Using 1x material over a 48" distance this is likely to happen. So even if, initially, you are able to find straight pieces and build them straight and square, over time they will start to move and probably not be straight & square after about 6 months or a year. So just be prepared for that. I am planning to build these out of 3/4" plywood instead. It will be more labor intensive and require a table saw to cut the plywood down, but plywood is much more stable than solid wood, so will have better longevity. That's probably the primary reason they use birch plywood in their production models.
- In the same realm as above, using 2 screws to hold the pieces together is ok, but I would caution people to be very careful when driving the screws, especially when using solid wood. Solid wood is prone to splitting when you drive a screw too hard, especially on the ends. A better design would be to drill dowels where the two pieces join together, and use glue. This will be a much stronger joint and you don't run the risk of blowing the wood out with a screw. Again, slightly more labor intensive, and requires some waiting time for glue to dry, but would yield a much better product. You can buy dowel jig kits at the hardware store for ~$30-$40. These will help to make sure you drill the dowels in the right spot so that you keep the two pieces flush when you join them together.
do you know there is no the one and true mos effective technique for build?
if you screw, drill, paste with your own tech, it does not mean you are the best proved excellent top of the builders.
if you were experienced builder, you should know there are different ways to work, no tonly yours is the one to recommend
@@antonio.x22 I don't think I ever said my way was the only way to do it. I merely pointed out some issues that people could encounter when trying to build it in the way the video describes, and offered some suggestions on how to avoid those issues.
@@mdhalls86 that's the same with Indonesia
Are you actually 🧠💀
My dad was a carpenter and i helped him for years. everything this guy said was true. You on the other hand have the grammar of a 6 year old. @antonio.x22
ty very much. so the question would be: how do they perform?
I just built the Scatter Face. Works really well. Thank you so very much!! 🎉🎉
what is that black background made of?
much respect showing us how to do it at home.
Excellent video!
Thanks for watching 🙏
Thank you so much for the Pdf guide 🙌👏
44 by 7/8 😂 man that imperial measuring system haha
Confounded by fractions?
Not particularly. Of course my generation received a proper education unlike yours, so I understand why converting fractions to decimals is difficult for many. Must be terrible going through life with a high school diploma that is equal to our 8th grade education, and perhaps a bachelor's degree that was our high school equivalent.
@@scoutdogfsrhaha butthurt! I know it rarely does to Americans but did you consider the fact that people might not be from the states? We don't need "education" in applying the imperial system because we use a sensible system where it's not required.
@@scoutdogfsr Your incredible education taught you an incredibly unnecessary conversion skill
@@rufusstewart762 factual statements seems to insult weak minded people now.
Can you teach us how to build a space coupling diffuser? Those things sound soooo beautiful
whats the difference between the diffuser with slats and the onces with all the holes drilled into it?
Thank you so much for this video!! 🤟
Hi @stvticsteve7249, Thanks for tuning in! :)
Very informative video, thank you.
What is the black stuff at the back of your scatter faces - is it fabric?
it's a sound absorber, it's usually a thick box, about 4" thick, stuffed with some dense insulator like rockwool
Would the Scatter Face diffusor work well for a tiny room to help with first point reflections?
Regarding the space coupling diffuser, do you mount it directly to the wall or should there be an air gap between the diffuser and wall? It looks like the diffuser is about three inches thick and the slats are 1/4 inch thick?
I'm considering having one made 72"X42" for behind the couch which is close to the back wall.
Thanks for your information!
thanks for sharing this guys!!
What frequency range will the scatter face panel in the pdf help with?
Did you ever get a answer for this?
@@TyGuyPS5 Nope
Hi Steve!
For any other information you might have, you can contact Music City Acoustics, they´ll be happy to answer your questions www.musiccityacoustics.com/contact-us
Did you get a answer?
Did you try this?
Scattered looks cool and weird at the same time. I’m trying to wrap my head around if it’s feng shui?
Great video! I downloaded the PDF. However, I'm building 48x32 acoustic panels. What would the board spacing specs need to be for the ones I'm building, since your panels are 48x24?
My rectangular absorber panels are mounted horizontally, at random distances from the wall. I am trying to add diffusion to the back half of the room. I was considering putting some sort of scatter face over the absorption panels toward the back of the room. I would love to see some kind of visualization of the interference patterns off of one. I was planning to rip random-diameter large-diameter plastic pipes (rather than Sonotube) longitudinally into long 1/3 sections and mount them over the absorbers. I understand that it's the interference between discrete somewhat specular reflections that causes the diffusion, yet somehow the idea of discrete reflections bothers me; I suspect I haven't got my mind around what the timing between these refletions would be. I am trying to visualize what the horizontal duffuse field would be like, versus the vertical. The bottom line is that I am considering mounting the scatter face slats the wrong way, horizontally instead of vertically. Of course that idea was originally born out of using curved sections of pipe or sonotube rather than a flat scatter plate.
How to make all three defussers in diy style ? Hope to see in next video, thanks
We certainly will look at doing these videos in the future!
@@ADAMAudioBerlin 🙂
Cap
What if I use metric system like a normal person?
How much space do you need for a root diffuser to make sense?
What kind of diffusion would you recommend above the piano 9ft ceilings.
Hello,
Would it make sense to create scatter face hexagon shaped versions?
I'm sure it would work just as well, but it's a lot more difficult to make
Did I miss that part when they describe the panel that they install the scatter face on???
My question, exactly.
Tried to download that "free design" with no luck ???
Hey , awesome guide. What is the black material behind the panel?
I believe it’s just fabric. I didn’t like how they just skipped to the end but I guess the pdf in the description is more detailed?
@@emyhR Nah, just the cut list. They don't have a suggestion for screw sizes either. I wound up using 3" and 1 5/8".
@@emyhR Nope. Just the frame is shown in PDF
Any reason you didn't use MDF? It is easier to work with and no bows etc.or is it because wood looks better.
I suspect the MDF would require bracing as cut into strips it wouldn't be as rigid as the timber section.
If you put a screw that way on a MDF will split.
nope, MDF will work fine, in any case just pre drill a small hole. It doesn't need to hold 30 kg's .. just a bit of wood and foam.
If you want to be cutting all those slats yourself with MDF which is not healthy to breathe in and heavier and needs glue...
I just made a diffuser. So cool! What is the model lined with? What is the black material?
Can you clear up a doubt? I'm wanting to build a Scatter face, and I don't really understand if I need to put some type of material like rock wool inside it, or just a fabric. How did you make yours?
I know I'm not OP, but I did end up lining mine with 100% cotton. It was a thicker material made out of leftover pants. If I would have purchased materials, I would have gotten a Duck Cloth.@@klaytongaldino5261
Hi Eric!
thank you so much for your interest! Under the following link you can find further information regarding the assembly of the scatter face diffusers:
static1.squarespace.com/static/614a68d7da23344679d80759/t/6247023a0bfcf20cd01cac18/1648820798130/Scatter+Face+Assembly+Guide.pdf
You can see there that the scatter face diffuser is placed on top of an acoustic panel. I hope this answers your question!

I’m having trouble reconciling the cultist with the board spacing. It seems the 1x3” will be reduced to 2 1/2”, while the 1x2” will be reduced to 1 1/2”; is this correct?
Hi @MatthewPSorensen! If you´d like to have more detailed information on that topic, feel free to reach out to Music City Acoustics directly:

Fantastic guys, thank you
Is there a way to build a space coupler diffuser?
Hi @ikeogueri9429! We will make sure to cover the topic in future videos :) Stay Tuned !
What is the spacing of the vertical boards on the scatter face?
Just added the PDF guide in the description 👍

You said there would be a PDF link in the description. Doesn't appear to be here. Can you post it please?
Just added it!
@@ADAMAudioBerlin Thank you!
What is the cleat for
Hanging it on the diffuser that's behind it
I live in an appartment with hardwood floor and have neighbors above, under and next to me. My main concern is I want to watch movies and play music while disturbing them as little as possible. Any tips on diffusion, absorption or anything els that would let me use my sub without needing to worry too much? Cheers
I recommend acoustic absorption rather than acoustic diffusion
I'll add: find a way to suspend your sub and not have it in direct contact with the floor.
Although low frequencies will carry through your hardwood, it's the vibrations from your sub being in contact with (a) surface that will cause the most noticeable disturbance.
Dream on. I used to live in a second floor apartment and had everything the same as you. I really tried to practice my bass guitar at a soft volume but I could hear the lady upstairs saying to someone: "This is what I have to listen to every night." The people downstairs would yell my name at 2am due to the floors squeaking when I walked. They were even letting the air out of my tires on my truck and turning down the temperature on my hot water heater which was in the common basement area.
Apartment living, especially on the second floor, is no place for woofers or sub woofers, even at soft levels. Put in for a different apartment on the ground floor in a corner as isolated as you can find. Then maybe all you will have to do is sound proof the ceiling.
They are called headphones
Awesome video's! Thanks guys.

I wish he was my brother !
44 7/8 inch? How much is that in cm? Would be great to have the measures in cm and how much distance there is between each bar
And what is that black surface behind the scatter face?
Hi 2pandaemonium2! You can just type in the value and let google convert it to cm. In this case it is 113,98 cm.
Regarding the material, you can reach out to Music City Acoustics. I Am sure they will be happy to help: instagram.com/musiccityacoustics/
All the best, Daniel.
I didn't put any acoustic panels sound Dolby Atmos perfect 👍
Hello Guys, what would happen if you took your diffuser, say a QRD, and filled the wells with a material like rockwool? Would sound get both diffused and absorbed? Thanks
🤔WHERE IS MY PDF? The link should download a pdf instead it solicits your email (WHICH I HATE) I reluctantly entered it AND STILL NO PDF?!! I don't want to be sold anything!!!!!! 🤨
Was Graham bitten by a vampire? Hope not :)
he said ,,,
we have jetzt , he means now , that was very funny , germans and englisch hhhhhhhhhh 0:52
where are the measurements? comparison? without evidence, people can speak and from the age of two they know how
I like your spirit man but all these designs you see here are well documented on the internet. Plenty of measurements and comparisons of these are readily available everywhere if you search for it :) Have a great day and all the best, Tobi
I only have one question: Was Graham bit by a vampire? 🤔
Interestingly, this video is about sound quality, yet the audio backing track (as I listen on my Android) is just distracting with only the high hat coming through sounding like a repedative glitch.
Go figure.
