and for amp a jbl bpx 500.1

How would i go to tune this around 34Hz. i would like to have a square/rectangle port. and is it better to make the port follow the side of the box like in one of the pictures?

also, how could i make the boxes edges round like the RE box? would the box stil be as strong?
