you want to figure out the displacement from your box?

LxWxH/1728=ft^3

Port Displacement

if it uses of the sides of the box for one side of its port wall, then:

(port height) x (port length-wood thickness) x (port width + wood thickness) / 1728

if the ports in the middle of the box, and has its own walls, then:

(port height) x (port length - wood thickness) x [port width + 2(wood thickness)] / 1728

Will round ports and slot ports of the same displacement yield the same tuning? :eyebrow:

Does port area = port area, or is it more complex than that?

port area = port area

,,,depends on the diameter of the round port and the face of the slot port
