View Full Version : Dual Slot Ports?

02-25-2006, 11:18 AM
I have a ported box that i am trying to find the port length to. It is a dual chambered dual slot ports. Each port, one per chamber is 16.5" after the wood displacement. What i need to know is if the 16.5" is my port length or would it be 33" since there are 2 ports. Each port is sealed off from the other so would the port length be 16.5" or would it be 33". This is my first dual ported box so i did not know how to figure the length.

I had a similar question. JL's supoport site has a breif tutuorial but didn't explain much to me because I wanted the slots in the middle/
