How do you determine the length of a port and how much space the port takes up.
Im constructing a sub enclosure 33x13x19(LxWxH). The box will be built with .75" thick mdf board and I need the port to have a length of 34.25". 31.5x11.5x17.5=6339.375/1728=3.6686198c^3
The port is 5" wide.
Is the amount of space the port takes up actually 1.13968461 c^3 or have I done some miscalculation?
I need to know how to determine port length and volume.
