At a quick glance they look quite nice (have not been able to download the PDFs yet). Wonder what they will price at. Here is the link:

These drivers are automotive fullrange and unsuited for hi-fi, for this reason they dont publish the freq range chart, only impedance.

probably good the alnico magnets are painted blue, so we at least can see a difference

but not sure I understand why they would be worse than other fullrange

edit, ouch, I see what you mean...very high Fs, means only with subs

Due the engine and traffic noises car audio speakers had to had a strong response on mid and hi's freq to be listened by the driver, and with these powerful car subs used nowadays...

The8in alnico one says its for home audio. It looks interesting.

Looks as if they can be used as mids with good result though

These 8 inches non ever had impedance chart, just TS, and the hi FS dont promise.
AN at least show complete charts; Last chance is if it had a low price.

Sorry, Alnico magnets have to be long to be effective. The short, squat magnets are ceramic. Either they are painted blue so you cannot tell that they are just charging more for the same, or they were designed by someone who is totally incompetent.

I'm always somewhat suspicious of of whizzer cones on 4" drivers...

Well Noted. I never see a Alnico magnet in toroid/donut shape.
Also there is many types of Alnico magnets, and few had good sound to hi-fi.
