Neodynium of Ferrite does not really matter. Shipment costs do matter.
Of ferrite models come closer to this one, I prefer ferrite.
I filled in shipment method. This does not matter. I am not familiar with Trade terms.
I uploaded a PDF file with graphs and specs. I am looking for woofers that come close to these parameters and specs. When ordered from western Europe I pay high shipments fees and the units are expensive. Off course top quality and warranty but high total costs.
Important factors in this case:
-Efficiency till 100Hz or a bit higher must be close to this Fane model.
-FS Frequency and Impedance must be very close to the reference model.
-Decent build quality. Also for future designs and projects. Trust is important. A lot of choice in all kinds of drivers and experience is appreciated
-Power handling must be equal or higher. A bit less is acceptable.
-Xmax equal or higher
-Rest of values may not deviate too much
-Higher unit price offers can also be made.
-Measurements files and small parameters is required

I am not familiar with payment terms either
