Win isd peaky response, error on my part?

[jlund10]

designing a box for a crossfire c7 10" plan on using the recommended 1.5 cf volume and tuning to 35 hz.
when i modeled the sub i noticed its ridiculously peaky unless i lower the volume to like 0.8 cf which is insanely low for a ported 10

Where did i f up? could a small mistake in the parameters be the cause?

You can't take winisd too seriously, and sometimes you can't take some woofer's t/s too seriously. Don't depend on that program for it's DB response. It can give you an idea of a rolloff, but I wouldn't worry about that peak too much.

I've been using winisd for 11 years or so, as one of the programs I can use.

Box size is usually right, tune the frequency and port to manipulate the sound to your liking.

Winisd is not accurate below 50hz because it cannot calculate vehicle transfer function aka cabin gain. Use bass box pro 6 instead. Its not a free program however.

Winisd is more for home theatre applications where transfer function is minimal.

BBP has always been a pay software, I just mention cost because everyone assumes its free like winisd and its not.

No, it was an online download. I don't have it anymore, it was like 7 years ago when I downloaded it.

I have no idea where I got it from, I think somebody recommended it to me.
