Huge magnets, cost more money.
Make this 18" driver with 5x time stronger = bigger magnet (minimum)
and this will be starting very interesting performance.

This driver apparently was build for use in an open baffle... so small magnet = high Qts (0.94).
Also the weight of the cone and voicecoil is only 45 grams... extremely low for a 18"????

Yes, I think the use is intended for OBs...

Do you mean like the magnet Lll Audio put on the Crystal 10 and its replacement the Silver 10?
Btw, anyone know if the 10's magnets are Alnico? Looks like it could be but no mention on the website.

Also getting back to the 18, the surround looks to be an accordion folded paper like a continuation of the paper cone and with a coating?
Again no mention on the site if the surround is paper, foam, or textile.

To be honest, i don't see the advantage of this kind of big fullrange drivers. There are drivers that are much better quality that are smaller and more efficient, and much cheaper. But 18" must mean a lot of beaming in the high frequencies. I would like to see some independent measuring on and of axis with good results before i would consider these...

Better make 18" with small size but super strong neodymium magnets

It should be a nice speaker for those who want a coherent sound and some "bass" with an open baffle.

I'd love to see tradeoffs in response and smoothness of increasing motor strength to say qts-0.31 on this and Fane's 12-250TC. (Are there any speaker engineers at Diyaudio who would lend some insight?)

- and lighter weight too but also the most expensive magnet option available.

Actually, short of a semi-custom type (which tend to be expensive due to economies of scale) a high grade AlNiCo is usually the most expensive to purchase. It's also usually the trickiest, and therefore most costly, to implement when high flux densities are desired in the VC gap due to the physical configuration -AlNiCo has some specific requirements in that regard which is one reason many drivers using it these days have relatively weak motors (in addition to usage requirements and marketing purposes).
