Anyone ever see a speaker with spun copper ports with full range driver?

Came across schmidtlambrixaudio.com. Looks like interesting design.

I watched the video on their website that showed the crude spinning process. Those things are not very precise at all. It looks like they use spun copper because the skill was in the family, not because there is any actual benefit.
