This will be my first time building a box so I'm trying to do it right, anyways I have been doing car audio for a little while now and always have had boxes built for me. My current setup I'm using is a single DD9515h on a SAZ2500 in a 2006 scion tc. Now like I said I had a box built for me that I am using but I want to change things up. On the new box I'll be using 1" mdf and I'm trying to calculate the port and how to tune but I'm going to be doing a square styled port like in this video DD 9512 - YouTube
The measurements I'll be running in the wedge shaped box is
width - 36.5"
height 1 - 17"
height 2 - 11"
depth - 22"
thickness - 1"
volume - 4.79167 cu. ft (before port and sub displacement)
tuning - 36 hz
Basicly all I need is the right calculator and or instuctions on how to determine the length and size of the port
