    JBL 2445_46 frq.response

    I have a pair of 2445 driver with 2446 ribbed membrane. measuring freq.response i have realized that both have deep notch "hole" about 3kHz ( about 15dB deep and say width about 1kHz/-15dB ). The picture is the same with an other driver too.
    Is there any explanation or experience about such bad behavior of 2445?
    It was 2311 JBL horn mounted on the drivers.
