    The basic formula would be to lower the port response by 20 Log (Port Diameter / Cone Diameter).

    Without math, you can lower the port response visually by observing the low frequency slopes. As frequency approaches 0Hz, the output of the driver and port will converge, so at low frequency you should see the slope to be very similar, and adjust the amplitude so the response overlaps here.

    An example:

    greetings from Austria!
    how can I merge the two magnitudes of a bassreflex box with omnimic (membran and tunnel) if I am doing nearfield measurements?
