Available on Amazon for more - but still very affordable. Anyone tried these? ua-acoustics.com/

I looked at these , the company is in the Ukraine. Just to check shipping cost on 4 pc was 48$ to Nashville . i don’t know anything about quality though.
I just built some panels out of rock wool that are 16x47x 3 1/2 and covered for roughly 12$ per panel , probably took me 3 hrs to build 4 panels and taking multiple breaks lol.

Pretty good shipping for international prices, but I'd personally rather support ATS or GIK in the USA with comparable shipping costs. Never used GIK, but ATS in illinois was great with my last DIY panel build. Contemplating ordering some pre-assmebled ones this go around to save myself the hassle. Can never have enough treatment here in the ol bedroom studio.

Looks pretty good, I wish it was in the USA though. An 80" square is $100, that's amazing.

Those 20x20 panels with matching bass traps is purty. No idea how well they work, but....

I did a few rooms DIY back in the 00
I read a lot of books and learned some basics about room acoustics.
How to use calculation software or excel sheets.
In my head bells ring if a company is not showing graphs and or real life measurements. A wonderful thing is the Porous Absorber Calculator by Chris Whealy.
I used the Absorber Calculator for his base trap cube. Everything under 0.50 absorption effect is near to useless.
Is there serious base trouble, room modes under 50 Hz?
This thing won't change anything!!!
This is my 80$ homemade hemp insulation bass trap that goes from floor to ceiling.
It's up to you I would prefer a weekend of work instead of leaning on some nice pictures and fishy official Russian papers shown on the internet.

Interesting, mind describing its actual construction?
Thx!

No big deal you build a wood frame 500 x 500 mm from floor to ceiling you fill it with hemp insulation or other insulation that has an air flow resistance around 3.5 kpa. Housing it with plywood panels, leave around every 400 mm a 10 mm gap ready is your base trap that starts down @ 40 HZ. Do it in all 4 corners of your room.
You can't over base trap a room just use as much as you can....

Great, thx , the 10 ml gap is what tunes the trap ?

No I am pretty sure it would also work without the gap because sub low energy finds its way and builds up in corners. The trap for sure has no wood in the back.
I forgot to mention that you can wrap the insulation in foil.
It is best if you make small packs that you can stack, and then you go element by element as in high-rise construction.
On the floor element you may want to mount furniture wheels which can handle the weight and do not destroy a wooden floor.
Its great for moving the trap - vacuum cleaning...

Ok I’m trying learn something here , so wouldn’t the hard panels or foil cause reflections and also not let the sound waves pass thru ? I realize that is what the gaps do, but seems to be quite a bit of hard surface . I’ve always read you use a material on the front that you could blow thru . Am I not understanding the design?

It's just for base energy up to 400 Hz.
It goes in there no matter how I pack it.
50 Hz for example is about 22 feet (6.71 m).
Tons of energy traveling in the room and that's, depending on the geometry of your room, a big problem. Such a base trap will solve most base problems.
At least it did in all three rooms with problematic dimensions I worked in...
EDIT: If you don't trust the foil use some light fabric and wrap it in there.
