PORT Size Calculations and Formulas for WOOFER and Subwoofer BOXES
read the bold and then if you dont understand that keep reading.
on this site in the port length calculator, under the box that says enclosure volume would you put the total area of the box in which the port would be inside? or would you put the volume of the space your sub needs and then add the port on to that?
So lets say you have a 12x12x36 inch space to put a box.(ignore the wood thickness) you have 3 cubic feet. so would you put three feet into this Calculator with a 6x6 port tuned to lets say 34(random numbers) you get a 23.02in length for the port. So the total volume of the port is (23.02x6x6)in=.48 cubic feet. So the QUESTION is would you have to build this port on the outside of the box or would this port go on the inside of the box. If you put it in on the inside of the box your sub(s) would be getting 2.52 cubic feet.
I can try to explain better but over the phone is better.
