About 1/2 are added by me via specs from RE and others are auto generated. It's ok though, don't trouble yourself with this. I'm probably just going to use the RE Enclosure Calc online.

 

Oh... just curious if it matters whether the ports should be left/right side of box or in the middle next to eachother. I see both types designed and wondering if there is a difference or just a matter of preference.

 

So I've come to the conclusion that the values you're missing aren't all that important. You have all the values required to make your enclosure.

Ports should usually be on the front, and as far away from the sub driver itself as possible. They don't need to be beside one another.
