Default Old italian RCF speakers (alnico?)

Just found these nice '60 italian RCF speakers. I wonder if they have ferrite or alnico magnet...

mmmhh , nice ? I have a pair similar ( circular holes in the basket instead of rectangular )
but the one piece cone-suspension ...Parsec ? Maybe . Not the speaker I would call 'fast'.
Good under 500 Hz ...I removed the whizzer ( useless at all)

It seems that you don't like them
Under 500 hz? I could use them as woofers?

What about the magnet?

I really can't distinguish magnet's material ...sorry
Yes ,finally , woofers . But the coil ( 3,5 mH ) plus the cap ( 47 uF ) is worth the value of the speakers ?
Tried them for a try as midranges , they 'corrupt' the sound .

Magnet looks ferrite, and the baskets -- right down to the label -- sure look japanese.
