Romy,
there are box-speaker manufacturers that use exactly this approach, so nothing is so new about it. I think Karma and Evolution Acoustics speaker (also layered construction) come to mind, see below.
As to CNC routering, it needs a CNC cutting program written to produce the numerous layers. This would be a cost amortised over the number of cut. But today's CNC routers should make that a pretty quick task as all be different size circles, yes?
The ONLY thing I can see to be an issue, are the ever changing angles / degrees of each 'slice's' in- and outsides. I would imagine your man would still have to smooth them over on a wood-lathe after all is glued up --- it still would be a lot easier since he has the already existing edges to work from.
If you look at the speaker above you can see, there are no curves in the vertical but only in the horizontal, which is no problem for the CNC router. (Your horn when compared to the speaker in this picture would fire upward, if this makes sense)
