K I got my swatches from myfabricdesigns and these guys actually put on a color spectrum on each piece thankfully. Here's what I found:

Breath test (in random order for each category):
High: Performance Knit, Modern Jersey, Polyester Slub Jersey, Polyester Pongee Silk, Polyester Crepe Jersey, Faux Linen Slub Sheer, Flame Retardent Faux Linen Canvas, Silk Crinkle Linen, Silk Crepe de Chine, Organic Cotton Sateen
Medium: Quadri Performance Sport Knit (borderline high), Faux Linen Slub, Faux Linen Canvas, Interlock Blend, Organic Cotton Jacquard (borderline high), Linen Cotton Canvas, Cotton Silk, Cotton Voile, Organic Cotton Interlock Knit, Cotton Poplin (borderline low), Premium Cotton, Basic Combed Cotton, Polyester Velour
Low: Polyester French Terry, Silky Faille, Heavy Cotton Twill

Printing quality (in random order for each category):
High: Modern Jersey, Polyester Pongee Silk, Polyester French Terry, Silky Faille, Cotton Silk, Heavy Cotton Twill, Organic Cotton Interlock Knit, Organic Cotton Sateen, Cotton Poplin, Basic Combed Cotton
Medium: Performance Knit, Interlock Blend, Silk Crinkle Linen (good colours but possibly too see through and with lines visible), Linen Cotton (same as previous, less see through), Silk Crepe De Chine, Cotton Voile, Premium Cotton
Low: Quadri Performance Sport Knit (lines throughout), Polyester Slub Jersey, Polyester Crepe Jersey, Faux Linen Slub Sheer, Faux Linen Slub (bright colors but visible lines bother me, might not for other people), Flame Retardent Faux Linen (by far worst), Faux Linen Canvas (holes make blurry image), Organic Cotton Jacquard

Using this info, I think there are a few top options.
Modern Jersey - Colours are sharp, well defined lines, very little bleeding of colours, not see through at all really. Fabric is very stretchable if that's something you want, which obviously hurts the print quality. Breathability is high and one of the better for good quality print options.
Polyester Pongee Silk - Basically the same description as Modern Jersey while edging it out ever so slightly in light grey colour as well as breathability. Black not as black though and colours not quite as bright. Medium Stretch
Organic Cotton Sateen - Good colours and black level, odd print shape that looks like the fabric moved in printing that is scaring me away from this one.
Basic Combed Cotton - Really good print quality, colours come out great and next to no bleeding in the text and colour wheel with good black levels. No stretchability. Little bit more see through fabric with slight visible lines up close but not at arms length. Slightly worse breathability, but at the higher end of the medium level for it.

Haven't decided which way I want to go yet. Picture shows the 3 main options IMO.

Not entirely scientific test number 2, i played a movie on my phone and covered the speakers and i honestly didn't really notice a difference between most of the fabrics, outside of the least breathable fabric and even that wasn't a huge deal.

In the end I went with Basic Combed Cotton, mostly because the lines come out crisp and has the least amount of bleeding/blur. I also wanted to get a fabric that doesn't stretch because I don't want to distort the image. Who knows if that's the right call but I think it should perform well enough.

***BONUS*** While these fabrics are already pretty cheap, it is worth noting that they are actually having a sale until the end of Sept for 25% off when you use the coupon code HIP so it comes in even cheaper than that if you order soon.

Very helpful writeup! Would be great to see how these turn out.

I might add 3 more posters to my room and my fabric design seems substantially cheaper than fabric on demand so will probably get the prints here based on your feedback.

I also got cross spetrum labs calibrated umik-1 and in the process of measuring the in room response with and without the posters to see if it shows up on graphs.

I'm rethinking my purchase now too to go with modern jersey. I initially thought it might be better to go with a non-stretch material but have been debating that since I purchased it.

EDIT: So I've called now and am changing it to modern jersey. they are checking to make sure they can go through with it, but sounds like they should be able to because they are so early in the process.

If you have any questions to help you out with the swatches let me know and I would be happy to help.

I now have to reorder my posters using the new fabric which I plan to do tonight, so hopefully if there is any objection to using the prints I will get them long before the end of September so that everyone waiting will be able to make their orders still using the 25% off code HIP.

Thanks. Nothing specific on swatches. Modern Jersey looks likes lot like "spandex knit" I ordered. Would be good to know how your actual printouts look.

By the way I think stretchy material will be fine. Some advantages I found when working with my frames.
  • Stretching only slightly < 5% doesn't seem to affect the image detail and makes it even more breathable.
  • If you are making your own frames, they may not turn out to be perfect rectangles depending on what tools you have. In my case it was easier to handle slight frame size differences with the stretchy spandex knit.
  • I printed my images 1/2" smaller than actual frame.
  • As you mentioned, some care is needed for the text near frame border to align it properly otherwise rest of the image around the center doesn't show any distortions.

Haha ya this is what I was thinking about and partially why I switched from cotton to modern jersey in order to be able to stretch out to exact spots, while also fixing the possible shrinking which would ruin the whole thing regardless.

My apologizes for asking, but when ordering from myfabricdesigns, which material was deemed the best for covering speakers or having the best transparent acoustic quality? I was planning on making poster prints to cover in-wall speakers.

Finally got my fabric in! This photo makes the blacks look washed out (#phonepic), but in reality they're nice and dark. Very happy with the print quality on these. Next onto the frames!

Oh boy, I'd be careful here. It took a long time to get that sorted out with Spoonflower and required actually testing speaker response both with and without fabric samples over a speaker using mocked up frames to hold the fabric types tight and testing in a very controlled manner.

I don't think that we are there yet for myfabricdesigns...

Acoustically Transparent for using in front of a speaker requires a quality testing microphone and software, not just "the blow test" that is helpful for acoustical panels. Heck, even fabric that you can't blow through many times still works great for absorption panels like this thread is all about.

I do happen to have the testing equipment and know-how of doing a scientific test and measurement for acoustical transparency, but I don't have the fabric samples, nor does anyone here have samples large enough to use. I would need fabric pieces that were about 16" x 20" in order to do an official test.

Anyone want to order and send me some? You would pick the fabrics that were deemed by others from smaller samples as having good image quality, plus the most breathable as possible to start with.

Yeah, all of the fabrics had just enough sheen to them that cameras pick this up, in combination of just auto light adjustment, and the blacks always look washed out in photos compared to real life. As long as the fabric isn't "shiny" when printed, you are good in the room too (so that you aren't making light reflective panels that are annoying when watching movies).

I am not saying that your fabric choice is, just making a comment that the blacks probably are a TON better in person, and for others to consider the "shininess" of any fabric so that you aren't reflecting a lot of light as well...

These look good
What is the printed size without borders and what frame size do you plan to make?

The posters without the padding measure 25x38. I plan on doing a 1x3 frame (or maybe 1-1/2x3, we'll see).

I used 1x4 poplar (for nice straight wood without being expensive) for my side walls, and 1x6 for my rear panel.

Works really well and stays straight. No need to go to something thicker. I like the 1x4 before I could get a 1.5" air gap behind my 2" insulation to increase the performance of the panel.

I just used a 1"x2" (actual size 0.75"x1.5") and then mounted it to the wall with 2 brackets that make it floating 1.5" from the wall. Used Roxul Insulation Sheathing that is 1.5" thick but very dense. I already have that mounted with speaker cloth covers right now, and will keep the speaker cloth covering the back and flip them around. Then for the frame I cut out a bunch of sections out of the frame to allow more sound to reach the panels.

It looks like myfabricdesign is the place to go now? If so, which fabric does everyone recommend? I have a few movie posters I'd like to have printed.

AIR GAP for the win!

I've seem some older posts with people having what I call "floating frames" out there to get the air gap. Haven't seen that done in a while, but it is still a 100% correction option. Nice job!

I like the look of floating personally, just seems funky instead of it just being a really thick frame. Air gap is a definite must. I actually mounted one huge panel on my ceiling too and that has probably 3 inch air gap that might be too much. Then I have 2 corner bass traps 6 in thick on 45s in the corner with double 3" thick regular roxul.

How thick is your cloud panel? It looks a little on the skinny side, but still 1000% better than 99% of what others do.

Same thing, 1.5" Roxul IS (same as Comfortboard 80 for us Canucks). I needed extra support brackets to make sure it doesn't fall out and on my head size it's 72" by 32".

Seems to have pretty good acoustical performance even at 1.5".

I am building 3 cloud panels and to keep them all at same level, one panel will be very close to 7.5' ceiling vs other two which would have 12" air gap and hang from 8.5' part of the ceiling. I am hoping it would help with bass absorption.

Yes, there is a threshold for how much air gap in order to have maximum efficiency and results. It really depends on how much area your panel takes up. Let me explain.

The idea is that the sound waves go through the panel, through the air gap, bounce off of the wall (or ceiling, or whatever), back through the air gap, and back through the panel.

You could, if the air gap was large enough, have the sound waves, go through the panel, through the air gap, bounce back, and basically just go into the room and not back through the panel (only 1 pass through the panel). Or have sound waves that go behind the panel (not through it) bounce off of the wall, back through the air gap, and through the panel (1 pass through the panel).

Now of course if your entire wall (not saying to do this, just for argument sake I bring this up) is one large acoustical panel, then yeah, everything would go through the panel, then air gap, bounce, air gap again, and back through the panel no matter how big the air gap was. Somewhere in the middle is the magical number for the panel size and how much air gap it can accommodate.

Most panels, if they have a really big air gap, would have to be placed at a location that is not the first reflection point of the room in order to get the sound waves to bounce through the panels twice.

So that all said, if you need to do it for aesthetic reasons, then you need to do it for aesthetic reasons. Science can't always win out fully if something needs to be pleasing to the eye as well. You will still get the absorption of the panel, and there will be an even number of sound waves getting treated by the panels. Some will only go through the panel material once, others will be twice and benefit from the air gaps, but you will actually be able to treat a larger area of the hard ceiling with the bigger air gap. It is just that it won't be a "double pass" through the panel and air gaps for a lot of that area, and it might not cover enough of the first reflection points, but it will still be a lot better than nothing.

The thickness of the panel itself will become a bigger factor in this case as you will want to maximum the effectiveness, and if you can't rely on the air gap working totally in your favor, then a thicket panel would be recommended.

Thanks Nick, makes sense now

The total coverage of ceiling panels with be 4'(l) x 6' (w) and 4" thickness (knauf ecose again). With 4' (along the length)I think I would have enough length make the 1st reflections pass through the insulation twice (measured a bit more accurately and airgap would be closer to 9" rather than 12")

Just got my shipping notification. Looks like they will make the panels just fine. I eagerly await the prints.
