ESS AMT 1AM - original 12" woofer info

[FORNO]

Hello,

I need information on the original PAPER cone woofer installed on ESS amt1 am.

I found two sets of initials in an old catalog: 12" with 350 max power watt, and 12" CF with 200 max power watt.

1) Which is installed on ESS amt1 am ? 12" o 12" CF woofer?

2) You can have the diagram of frequency response ?

3) You can have some other information?

Many thanks

Federico
