[QUOTE="BurnerOfHells, post: 234612, member: 548395"] Since the top and bottom of the port are box walls how should i determine the proper port length? What im wondering about is end correction. Do i use the typical one half the port width for end correction or since there are 2 sides of the port that are box wall do i do something else. Heres a picture of what the box and port look like [IMG]http://members.shaw.ca/m-steele/boxport.jpg[/IMG] I have looked at the info at [URL="http://www.carstereo.com/help2/Articles.cfm?id=31"]http://www.carstereo.com/help2/Articles.cfm?id=31[/URL] and [URL="http://www.carstereo.com/help2/Articles.cfm?id=33"]http://www.carstereo.com/help2/Articles.cfm?id=33[/URL] basically it seems as though this end correction can only be used on a port that only has one of its walls part of the box not 2. What is the proper end correction i should use? [/QUOTE]
