Life after Frugel-Horn Mk3

You've answered your own [non] question there. 😉

Yes, the Alpair 10 series is discontinued. After 15+ years the jigs were at the end of their useful lives, and the original basket design, though still effective has been superseded by more recent types. Large parts of the 10.3 live on in CHR-90 though, in a similar way to how much of the old Alpair 7.3 continue in P7HD.
 
I guess what I was trying to get at is what is the successor (or upgrade) to the Alpair 10.3 for builders to consider

or is the Alpair idea a dead end as a direction?

You can see the current ranges, including the Alpair series units, on the MA website, with their relative dimensions etc., which is probably more useful / informational than anything I could write here though. At the end of the day, depends on how much you want to be spending, how large an enclosure you want, what your priorities etc. are.

Which is exactly why they aren't investing a large amount of money in replacing the moulds, jigs etc. for a basket that's inferior to more recent designs. Spending money in order to stand still rather than free up funds to produce successors, direct or otherwise, isn't great business practice. If you're willing to pay to have them replaced like-for-like and keep the driver in general production though, I'm sure they'll be glad to hear from you. 😉

What you see in the model numbers no longer gives an indication of where they stand in terms of sound quality. Since the Alpair 7/11ms came out and we have Alpair 7.3 demoted to Pluvia, and now it is confirmed that A10.3 demoted to CHR. The decendands probably work even better than where they come. The CHR/CHP 90 are certainly well liked. Smaller size likely improves mid/top.

And then there are the odd-balls, CHN-50/110. Dirt cheap stamped baskets, very good on merit, amazing for the price.

The newest one pushes the limits of FR MA cones. A decade ago Mark said he had to really push to get the metal cone A12 (A16.5 in the new numbering system i guess)

Pluvia 11
Alpair 11MS
Alpair 10.3
Alpair 10P
All these drivers are available, about the same price and work with FHXL. I've looked at the specs and the write up on each but what is the benefit or sound signature compared against each other. No point making 4 different units if they don't bring something different to the table.
