No it doesn't work that way, you have it backwards; with more port area (2 6" ports vs. 1) they'd have to be longer in order to keep the same tuning frequency.

The only way you'd get away with less port length is to reduce port area.

well isnt the rule of thumb dont let the port any closer than the width of the port to the wall of the box? cuz i want a 6" port but my box is only 18" long and i need a 16" port

Then you're doomed to a 4" aeroport. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

I'll trade you a 4" aero for your 6" aero. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

This, or you'll have to tune higher.
