[QUOTE="Immacomputer, post: 2705349, member: 570419"] I would like to know how they came to their conclusions. It's not logical at all. My way is much more logical and correct. I don't know what CAJ (car audio junkies??) is but the people over there are wrong. That's all there is to it. It won't change tuning much (maybe 1hz or so) unless the port is pretty wide. In some cases, you could be adding up to 3 or more inches to the port length which could possibly be a rather significant change in tuning. Here is a little bit about end correction from JL: [I]"The effective length of the port is found by adding an end correction factor. An end correction factor is necesary because more often than not, one wall of the port is also one wall of the enclosure and this wall extends beyond the end of the port thus effectively adding length to the port (remember, the driver can't "see" the length of the port, it can only go by what it "feels" is going on)."[/I] [URL="http://mobile.jlaudio.com/support_pages.php?page_id=165"]http://mobile.jlaudio.com/support_pages.php?page_id=165[/URL] [/QUOTE]
