im making a box for a 12" sub and it is 1.2 cubic feet (that is what the sub needs) but do i need to port it ? what diffrence does it make ?

As it's a 12" sub in that size box it will be a sealed box. A ported box will be louder at the port frequency but under that you don't get much. A sealed box tends to provide more lower bass and a smoother frequency plot.

Basically,

For SPL a ported box is better, for SQ a sealed is better.
