port area in Torres

[pioneerforlife]

Ok so I am building a box for one of my friends. he has a single Soundstream SPLX15. this is my first time using Torres and I am a bit confused between port area and port area per foot. which one should I be looking at to find total port area. the box is about 4 cubes and tuned to 36HZ. I want to get about 50 square inches of port area but I am not sure the difference between port area and port area per foot.

Port area = total port area

Port area per cu ft. = how much per cubic foot

For example:

You have a 5cu box with 100sq in of port (Port Area)

Port Area Per Foot = 20 sq in

Port area is total port area - you have indicated that you want this to be 50. Port area per foot would be the total port area divided by the net volume of the box. If the net volume is 4 cubes and the total port area is 50, then your port area per foot would be 12.5 inches per foot. - 50/4 = 12.5.

ahhh ok that makes sense. also just wondering if 50 square inches is enough for that driver.
