I used to use winisd to make my ported box designs. I've been out of the car audio scene as far as buying new products etc for well over a year. I was reading some basic tutorials on google on building ported boxes cause to be honest I kind of forgot. Anyway, I went into winisd modeled up my gizmo, but I noticed that there was no vent length listed. I thought wtf? So I got winisd pro, modeled it up, and everything I needed was there...
Do I have a messed up setting within winisd? I remember using that for everything and it was fine, but this time around it seems like I need winisd pro to get the basics done.
