    "invalid floating point operation" is the pop-up I'm getting. I'm sorry to bother you guys with this stuff. I can just use beta, but I hate when I can't figure something out.

    Sounds like you have a number with an extra decimal somewhere.

    It's not a bother. I had similar issues with it not cooperating. That's why I went back to the beta, and ultimately ended up using Unibox for this sort of task.

    How much is unibox and where can I get it? I thought parts express carried it but I just looked and it wasn't there. I also googled it but what I downloaded asked for some code on the back of your cd. Which I don't have. Or is there a free version?

    Should be free @ FRD Consortium

    It's excel based.

    Thanks, Its not letting me download yet but ill try again shortly. In the meantime, could someone help me understand the effects of the phase plot and group delay. The group delay has a 40ms spike @ 31hz and I dont know how to interpret these effects.

    Check out this paper from Dan Wiggins Subwoofer Group Delay - Adire Audio.pdf ( http://www.adireaudio.com/Files/GroupDelay.pdf)

    Group delay is less audible at lower frequencies. I believe Dan's rule of thumb was to try to keep the product of group delay * frequency less than 400.

    semi off topic here, but is there a program similar to winisd that utilizes higher frequencies for say midranges or full ranges?

    a little late to the game with this reply, but BassBox 6 seems capable of doing such a thing. it has a decent list of manufacturers' drivers available to pick from with the update that is offered from the site.
    i should really stay off of forums after a few drinks.
