Port Size

Hi I just got my 12" BL and I'm starting the box for it. The box will be about 2.6 ft^3 and tuned to 33Hz I was just wondering if a 3" port would work or if i should use a 4" port. I'd like to know if there is any difference in SQ or output with a different diameter port.

Use a 4" aero and tune it accordingly.

ok thanks. the only thing is i can only do 10" should that be a problem?

depends on how far you are from the back of the box, i dont have a box program here so i can't calculate the proper length to tune to the given frequency that your looking for

there will probably be about 5" from the end of the port to the back of the box
