Interesting company. Are they 3d printing with a concrete mixture? Many things on their website appear to be printed with a composite (plastic) of some sort? That egg speaker should be his best performing down to 200hz and used in a 3 way.

This is very cool. I'm looking forward to an open baffle kit with a Neo3 tweeter in a waveguide and a 12" midwoofer in ultra black concrete with shimmering dust particles throughout.

Concrete cabinets won't be cheap. The weight will be a significant barrier, and the shipping costs will be outrageous!! Most audiophiles are old guys, so super heavy components aren't enticing. These factors will severely limit the market, especially since MDF of the same speaker will sound 99% as good.

No, it's a 3d printed mold that it then filled with concrete.
