The length of the port is based on the tuning frequency. What you are mentioning has nothing to do with the depth of the port. For what you are aiming for, you would have better options with fifteen-inch drivers, as you are not looking to achieve a very low response.

If you have your heart set on eighteen-inch drivers, just build the G Sub and use the FANE 18 XB. The G Sub was designed for that driver.

More like sound quality wise.   Like if a short port made a certan kind of sound, and a long port another sound.   Brg.

I don’t know who is filling your head with this nonsense but, I would strongly suggest you stopping listening to him/her.

If the G Sub is too big then just cut them in half. Surely, you can carry half a G Sub?

Nevertheless, I think it is time for you to start learning the basics
