Measuring Port Length


Texas Tech

Recommended Posts

Here are two Simple Diagrams from Paint Program. I want to know how you would calculate the length of the port,given the measurements. Just what you would add up and the answer. Thanks

First, i have given the lengths measured down the middle of the port, and width of the port.

Second,I have given a length, and a width (3 inches). I also want to know what the length of the red line should be, or does it not matter.

The length of the red line in the second pic should be at least the diameter of the port.

A couple links to some box builds:

Tahoe Box 1, Tahoe Box 2, Nissan Titan, VW GTI,

Mini-Bump, Hummer H2, Ford F-150

My own car builds (current setup --- under construction):

Overall Thread, Kickpods, Dash, Back Doors

Subwoofer Wall

doesnt matter a whole lot, just if its less than the diameter, it creates a choke point.

would the first port have a length of 20.5 inches?

and the second...16.5

And if you cant give each sub its own chamber, would you say that one port down the middle would be better
