NRC is measured on a scale that ranges from 0 to 1. An NRC of 0 means that the product absorbs no sound. An NRC of 1 means that the product absorbs all sound. This product chart has a fictional axis, therefore the data and conclusions can be considered fictional.
I wonder if they are making the same mistake as Uplift acoustic products and misreading the PET specification. I think it's e200 which (if i recall correctly) means enclosed cavity with 200mm of space.
As any false advertising.
I have great doubt that they can make fully porous bass trap with decent efficiency at 100 hz and below within this size.
Maybe they have composition tuned helmholtz+porous? Both layers can be done from PET.
There’s very little difference between the measurements of my tuned membrane GIK bass traps and those artnovion traps, they look very expensive but they do look more stylish

I would agree, although the ArtNovion tests are proprietary, not done at an acoustics lab. It's hard to compare results directly, but the ArtNovion designers have good pedigrees, one of them being Bruno Fazenda, a well known acoustics researcher.
The other matter is that the ArtNovions panels max out at around 2.7", while the GIK Scopus panels start at 4" and the thickness increases with their wooden panel. The latter also have higher Q absorption.
Looks like most effective pressure based solution for end-users. Tunable!
For sure, it can't be cheap just because of design itself: it's huge square passive radiator in a sturdy box.
