Port placement, subwoofer placement? Need Help!

[BassHeadBlakeYo]

Okay, so I used to know the answer to my question. I forget, need help with this.
What is the optimal subwoofer placement when designing a box? Like where would you put the subwoofer compared to the port.

I'm going sub up, port back.

But I completely forget where to put the subwoofer. Closest to the port, or away from the port?

or

You want the sub away form the inner end of the port, it can be close to the port, such is the case in the following design:

 

 

 

The  sub is close to the port but not the inner end, no problem like that.

What’s up Blake, typically from what I’ve seen in boxes configured like that it is usually sub away from the port like in figure B. I have a box very similar to your design in my car now and the guy that made it for me made the sub away from the port just like figure B. You’ll love the sub up port back style. In an suv it’s awesome
