Hi,
I need to model a FOUNTEK NeoCd2.0 Ribbon Tweeter in Spice.
Are the parameters I am using ok?
R=6.5Ohms (for Re)
L=0.1mH (for Le)

(1)The problem is that they don't publish the Le parameter.
(2)Also the impedance is 7 Ohms (nominal) but in the graphics curve of response & impedance it shows impedance coming down to 6.75 Ohms @2kHz and 6.5Ohms @3kHz. Which impedance is the best choice to model in Spice, with x-over at 2kHz?
(3)What is this ---> DCR 0.02 ohm, from the factory .pdf catalog?
(4)I am not using compensation for HF, what do you think?

or here(http://www.madisound.com/neocd2.0.html).

Thanks Wayne.
Best Regards
