    Interpretation of measurements

    Good morning to all,

    I am not a sound engineer and I need some help to interpret measurements. I obtain reliable results when I place my microphone close to the loudspeaker (blue curve), but when I place it about 1 meter from the cabinet, in order to measure a full range curve for the 3 speakers, I get a severe dip close to 50 Hz (green curve), which is exactly matching the frequency of the second bump of the impedance measurement.

    Is there any relation, like phase issue ?

    Thank you for your help

    Dominique
