Re: sub box question
You would need to check and see what the manufacturer recommends for air space....it is different with and without ports if I remember correctly. Sealed boxes are tighter than ported boxes but ported boxes are louder.

Re: sub box question
A ported box, when done properly should give you a 3dB increase/driver. Your box will need to grow in size. Generally speaking, a ported box is 50% larger + the displacement of the port itself.
