Need help building an aero port!!!!

[cheese20323 13]

So i am building a new box as of this moment i have 2.5 net volume without any sub displacement or any thing. The driver is 1 RE SE12 . My desired tuning frequency is around 32-34 hz. I want to know what the port diameter and length i have tried some calculators but they are to long for the enclosure.

Go to PSP-INC.COM may need to build a new box

12-16 sq-inches port area per cubic foot of volume

Run external port or build a new box to take sub and port displacement into consideration. psp-in has a port length calculator.
