dude your post is way to confusing...

Without knowing the port displacement (im sure I could figure it up, but it would take forever with your description) sub displacement, and really an accurate discription of the box, this would be impossible to figure out.

You need...

Sub displacement in Cu. Feet.
Port displacement in Cu. Feet.
Port Area in Sq. Inches
Box Volume in Cu. Feet.
Port Length in In.

If you could speak English and type like any normal American, we might be able to help you out.

Judging by your typing skills, I would say you are NOT ok to start building this enclosure.
