[QUOTE="kickerlivinloud, post: 2805800, member: 552730"] I wouldn't trust that calculator. I have found it to be way off from time to time. It also is spot on at times. Its just not constant. Here is an example... [URL="http://forum.realmofexcursion.com/showthread.php?t=23030"]http://forum.realmofexcursion.com/showthread.php?t=23030[/URL] In the thread a person used it to get a 2.2@32Hz He had 42"^2 of port with a port length of 44.75" I did a similar design a while back and it looked like this... [IMG]http://i162.photobucket.com/albums/t246/Kickerlivenloud/Black%20Mirror%20Designs/BMD1.jpg[/IMG] As you can see the port area is the same and the volume is very close but, the port length isn't even close. Not by a long shot! Also if you take the info giving my the online calculator and add it all up, its doesn't match. I explained everything the best I could in the thread. I just don't trust online calculators. That my, I like to do it with pen, paper and a calculator. That why I know its right. Jon [/QUOTE]
