Okay this is my first time at building a box so don't laugh at my question :-(

This is what I have

Kenwood KFC-W3009

Sensitivity: 93 dB
RMS Power Range : 35-400 Watts
Peak Power Handling: 800 Watts
Impedance: 4 Ohm
High Frequency Response: 800 Hz
Diameter: 12 Inch

My question is when building your own ported box, When you know how many cubic feet you need...where does the port fit in the equation...

Here is a drawing i did to help explain what I am confused about.

*notice hightlighted port in left pic meaning the 1.5 CbFt does NOT include the vent.

When someone says the volume of a ported box is X.XX CbFt. Does this mean the value includes the port or excludes the port?
