anyone here use winisd?
i am having trouble with some of the parameters. my type r 12" 2ohm DVC spec sheet doesn't have some of the required specs, or i'm not exactly hip to the terms.
Z = i assume total resistance, so 2ohms wired in series is 4
PE = ?
BL = ?
Dia = cone diameter, voice coil diameter,...which one?

Thiele-Small Parameters.

And usually, diameter refers to the mounting diameter of the basket... But I could be wrong.

Re: anyone here use winisd? (builthatch)
Z is the impedance of the coil; in your case, 4 ohms.
PE is the power handling; only used with the "max spl" tab, which I never use anyway.
BL is the motor strength; if you put in a cone area (Sd), winISD will figure out the BL.
Dia would probably be the speaker size (10 in, 12 in, etc); not used for calculations.
