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

I can't speak to the copper port, but I have a pair of DNAs with the Alpair 10p and I love them. Terrific driver.

Machining them would be much more precise. 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.

Spotted them on the Primaluna instagram. I guess they’re looking to minimize phase distortion without the crossovers.

I think I've seen machined metal in Wilsons?

The most interesting functional design of a port I've seen were dimples on the B&W ports.

You do realize the use of copper is purely aesthetic? They need the looks to distract from the fact there's nothing new here.
