port length question

[Crown_amps]

ok so correct me if im wrong please. Using a 2.25" vent, if i went 8.5" deep and made the L shape and went 14.75" i would end up at around 30 HZ?

you cant guess this shit if you make one wrong cut it messes up the whole thing lol

google subwoofer box programs and make sure its decent

dont just guess

I wouldn't trust a lot of those subwoofer programs for good estimates //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif They don't take into account a lot of things in general....and can lead you in the wrong direction if you don't have some prior experience.

I've made a ported box before but it was with pvc pipe and its pretty hard to mess that up.
