yes but you have to remember each port will displace volume inside the box.
so if you box is 5.2 cf after brace and sub displacemnt. and each port displaces .5cf (useing my simple formula.) then you are really going to have a box that is 4.2 cf. and now you port length is going to change ..... confuseing isnt it.
this is why sketch up is such a popular program.it saves on alot of time calcualting displacemnts and such.
