Hello, In the Port Length Calculator site it says to enter in the Box volume. But is this before you include the volume of the port itself or after it? Thanks for any help!

Speaker 12w3v2-d4 recomended volume per JL is 1.75

Driver displacement is 0.07

My box now needs to be 1.82 volume to compensate for the driver displacement

Port volume is?

My box now needs to be?

Here's an example that will help you out...
your calculations indicates that your driver requires a 2.00 ft3 ported box. Your driver's displacement is 0.5, and yer port displacement is 0.3

Build your box to 2.8 ft3, and after your driver and port is mounted, the driver will have its required 2.00 ft3 space.

Again this is an example ...hope this helps. email me if you have anymore questions.
