port size

[mr foo]

i have a pioneer 12" in a sealed pioneer box, its a free air sub, so a port is needed for the best sound, is there a certain sized port i should get? the box has a 2.5" hole in it, which i plan to put the port in, is this good? or too small? or too big?

thanks

edit: or is it a better idea to patch up the hole, and make a larger one on the side of the box...?

thanks got the prog, it doesnt have my subwoofer though //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif...Pioneer TS-W304F, i did play round with it with some other subwoofers, and noticed with 2 ports the "vent mache" would decrease alot.

does it matter if each port is on a differnt side of the box? (1 behind the sub and 1 on the side of the box? each 66mm in diameter?

thanks

if you have the ts parameters for the sub, you can create a custom for any sub i.e. resonant engineering is not on the list but you can still use it.
