I wonder if there's a very small and cheap alnico 'hiding' inside

Chinese are masters of making look alike stuff
I bet they could do much better without

The Alnico magnet are 50x60, net weight=1100 grams. I do not know Alnicos drivers.
Do you think it is a big magnet for a 12 inches FR??

That's right at the same weight as Altec's 15" 416 AlNiCo H.E. mid bass horn drivers, so to address tinitus's concern we need to know its T/S specs to see if it's mostly just a heavy return pot.

I guess since Alnico is $44 per KG and Neodymium is $275 per KG--we will see more Alnico?

Interesting looking full range though--not common to see a large 12 inch beast so maybe a back loaded horn, BIB or something else can get decent bass out of one of them? Much easier to add a super tweeter and cap than deal with subwoofers etc. The Audio Nirvana stuff looks interesting but with a price to match.

Any more specs, the name of the company or ????

I do not know the price, but as it is a 12 inches, seems to me a price lower than the Nirvana Super15Alnico are acceptable.
I could suspect a $800/900 dollars/pair, just a guess.

Also, It would not be bad if this driver was the next Nirvana Alnico 12 inches FR, a very beautiful driver.
Regards, Gustavo

Not much magnet there, the AlNiCo 416's Qes hovered around 0.2-0.22.

Altec's 12" AlNiCo 414 had a smaller 1.8 lb motor with a correspondingly 'weaker' 0.33-0.35 Qes to give a frame of reference of relationship of magnet size Vs total motor weight, so tinitus's skepticism appears to be justified.

Still, with a ~0.7 Qts, it's suitable for a wide range of alignments, though with its relatively high Vas, most cab sizes will be large.

Not much use until we know how much, delivered, and availability. Until then it's just a teaser.
