Does anyone have a picture of a ported box using PVC. I'm looking for a picture with the top of the box 'cut off' to see what is going on with the PVC.

I don't think I'll be able to explain this too well, but I'm confused if the portion of the box with the sub is supposed to be separated from the rest of the box with the PVC connecting that chamber to the the outside of the box or if the the inside of the box is completely open.

If the sub was separated/isolated from the PVC port, then how would the port work? You'd have a sealed box for the sub AND a ported box with NO sub.....

Yea. The inside of the box would be open with no separation in order for the port to be a port.

basically i pictured the sub chamber to be separated with the exception of a 4" hole in the partition and 4" pvc feeding air into that sub chamber.

But, you answered my question that everything is open inside the box.

Does it matter where the PVC starts inside the box, like maybe have it close to the pole vent or is the only thing that matters is the total length of the PVC?

Is there any special reason that you started the ports near the pole vent of the driver?

this is a fairly easily removable PVC port I got pics of from somewhere?

It doesn't matter where the opening of the pvc port is, that's just how his is.
