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
I have looked at the info at
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?
