DC LVL 4 Enclosure

[DaJuice]

So I'm going to be ordering 2 12" lvl 4's here pretty soon. Im a noob when it comes to box building.

My question is about port area and volume. I have no idea what it should be

So just using a box calculator online this what came up with.

Gross box volume= 3.518 cu ft after speaker displacement

Net box volume= 3.3 cu ft

Using a 1- 6" aeroport tuned @ 36hz

Port area= 28.74

Port volume= .218

Would this be suitable for 2 12" lvl 4's?
