Well, the last time I checked, slot ports are NOT a diameter:

Joshua,

Slot Ports are defined by the Width x Height x Length.

So, if the width is 1.5" x the height of 16.5" x the length of 13.5" will define it's port tuned based on the volume of the enclosure.

Keep in mind that the port size w x h x l will displace volume along with the subwoofer volume will effect what the actual port tuning will be.

So, if you say 3.6 cu.ft. is the gross/overall volume, you have to subtract the port volume and sub volume to find the Net Volume, this is the volume you use to define the ports tuning freq.
