Bought this used 10" driver. The sticker says "K10" so assumed it was a Celestion. The magnet with the vents seems typical but the dust cap is concave. The surround has a single roll whereas in pictures the K10 has two. Also the K10 has a pressed steel basket and this basket is cast.
Any ideas?

That was a genuinely well intended, informed answer. Notice how I said cheap AND Chinese. Wow... shame on me for trying to help.
Beta Three use that kind of chassis - I believe they OEM for various other brands as well as making their own stuff (eg some of the Thomann own brand drivers), so that maybe doesn't narrow it down enough to be useful.
