Depending on the low frequency limit (if any), overall dimensions and cost to produce, this may be a 'holy grail' development for accurate, full range reproduction in the home, as well as project studios.

3D printing? It looks to me to be simple enough that basic carpentry skills should cover it.

I doubt that, because the absorbers are "relatively thin" to quote the article, although no measures were mentioned. Besides, I believe no "carpentry skills" could beat the 3D printing price.
