3D printed speakers? W3-2141 Tang band?

Has anyone seen or tried this?


I can't find any design specs... they sound good through his recordings.

I'm curious to get a friend to print, and try the HiVi B3N drivers I already have... BUT i know these are very different drivers.

Any ideas what the HiVi would do in that box? too much low-end? I may end up doing the Zaph box & circuit for the B3N's in the end, but I could always order a pair of W3's for this box in that case.
