    Actually all I need to plot is infinite baffle response with a first order filter ( for my purpose )
    Could probably do without Vas ....

    > "beta" (from 2014 - it's vers. 0.44)
    I'll look at that ...

    You can't get a useful result from Vas, Fs and Qts alone. At the very least you also need Sd and Re.

    Actually, WinISD "beta" (from 2014 - it's vers. 0.44) WILL plot a woofer's bottom end rolloff (and suggest a box size/tuning) using just those 3 main parms, but that's only 1/10th of the data that more advanced (i.e. "Pro") versions will show you.

    What's the aversion to a more robust ISD vers?
    You need to (really) enter about 9 parameters: Qes, Qms (Qts gets calculated), Fs, Vas, Re, Le, Sd, Pe, and Xmax.
    This has little to do w/your orig. ? though ...

    No program can work with just those specs.

    Is there a way to ' whittle down ' WinISD to work with simply Vas, Fs, and Qts ?
    ( Where's BoxPlot when you need it ? )

    Yes. Just adding a series capacitor and hoping the driver is resistive 8 ohms (for example) often gives surprising results.

    To get an accurate response (using .frd files) you need an XO simulator.
    WinISD can show various "transfer functions" - which are just generalities, AND do not take into account a driver's varying impedance (using passive components).

    In Unibox, you can add the transfer function of an active filter and/or in much more limited manner can add some passive components.

    It allows a number of filters, orders and Q. The superiority of higher order filters is pretty obvious when you overlay them.

    WinISD has that option. Just add a filter in the filter section. It will allow you to add a first order high pass.
