Guys, I need some help with a box design I am looking at. See the attachment below because I made a drawing of what I am going for. When you see the picture, please assume that the port height is the same as the internal height of the enclosure. Here are my questions:
1) Would this design be considered as having two ports? If the enclosure has two ports then I assume I would be correct by doing the port length formula for two ports?
2) Would the woofers see both chambers for airspace since I am not putting in a divider?
3) If the width of the mouth opening is say 3 inches, do I stay off of the back wall 3 inches with both bends or do I stay from the backwall 1.5 inches?
