I wish I knew more about driver manufacturing. I mean, is there a show where I can go and buy a woofer press? :)

The voice coil annual will take you, eventually..to someone or some group that can make that a reality.
Of course, you are talking about a cone press? Which is pretty basic, actually. You can make one yourself, but accurizing it will be your big issue.
Working with paper will be what makes it easier.
You can buy a smaller injection moulding set up and can have the moulds made for experimentation..for probably..under $20k. This is for plastic based cones, obviously. Since they are so thin, you are not restricted (relatively) due to a thing called shot size (volume of plastic per single injection). You could go from 3" to 12" cones on probably the same set-up.
Designing an effective mould and process for such thin materials is your biggest problem. The other way to do it is much like pressing records with lots of excess materials.
A paper cone cheapo set-up would be similar to a casting variant, or similar to a composite layered design/build set up.
A small CNC set up with good Z capacity (XYZ, maybe even rotation) can have you making your moulds for paper and similar materials..in quite a short time. A few dedicated months could get you there.
In the face of such things that require multiple disciplines be mastered and integrated... it is no wonder that machining of cones has taken off, and touted by some as being the best thing around. One can also machine and use that as a core for composite pressing, and so on.
Many possibilities out there that can each be touted in the given sales literature.
We quickly enter the ’different but possibly not better’ area in potentials, as we still don’t have a commonly known and utilized answer to what *exactly* the ear’s part is - in this equation. Lots of things still up in the air.
Which means argument without clear resolution.
