Got a pair of those dirt cheap, initial listening (free air) is promising. Anyone who tried them, and if yes what is the recommended box size and type for those?

Huh? Made of leather?
Yes, of course I looked up all available info on the web, what I'd like to know is whether anyone worked with this speaker, and what are the opinions on it.
That leather thing is a joke, most chinese descriptions contain some weird s..t ...... The back treated cone is some kind of compound type, with textil-like fibers in is, but I think it is paper based.

In China (taobao) this is branded "Correct" DG-603A (see picture). I have only used their leather-surround multiple-concentric-zone beige-cone P610-like whizzer-less fullrange drivers in 5/6.5/alnico8", not this other series rubber-surround white-cone with whizzer. Judging by the store's audioclips these white-cone have a more modern sharper sound.
(My stacked micor55 and alcor66 used the beige-cone, which weren't perfect but excelled in certain aspects so one wished they were.)

The translation between Chinese and western languages is is pretty poor. AI should solve that! 🤣🤣🤣
The one that gets me is the “bile” amplifiers. It has something to do with tubes shaped like a gall bladder. I’m not sure. It’s definitely a challenge. Also, I don’t know why it hasn’t been translated correctly yet, how long have we had tubes?
Having said that, there is no reason you couldn’t make a leather coned loudspeaker or have a leather surround.
