if you guys can help me out right now I'm using winsub and it's ok but I'm hoping there is better out there

 

in my opinion that is one of the best box making programs there is. and its the easiest too.

 

bassbox to calculate the dimensions and volume, and this page:

to calculate slot ports. All you do is design a sealed box with the volume you want in bassbox, then you include the slot port as a known mass that decreases the volume. This way you get the correct dimensions for the box.
