    2213H/2213/123A-3 = Positive voltage applied to the BLACK terminal results in forward cone movement.

    2212/123A-1/126A/D123 all share the same motor and are opposite.

    POSITIVE voltage a black terminal ??? BLACK ??? No phase test ??




    deaer I have 123A-1 and have tested It ..It is positive . and NOT OPPOSITE !!!

    2213H Positive voltage applied to the BLACK terminal results in forward cone movement.



    I still do not understand ... there was someone at the jbl who was not well headed they made a mess !!!

    It is what it is. Worked for them, and easy to test/check. Is that a problem?

    Not sure JBL really cared about what others thought. If you take a driver out, mark how it was connected or take a photo. Then test to see if the last guy messed it up!

    no problem I would just like to understand, ( positive voltage on black terminal....

    Not sure JBL really cared about what others thought.

    of course you... but if you are a big company and you create confusion ... I don't think it's ok


    If you take a driver out, mark how it was connected or take a photo.

    I have driver out my 123a-1 end it are positive transducer if test it with positive voltage on red terminal of the driver
    it are negative transducer if test it with positive voltage on black terminal of driver


    in both cases I disagree with data sheet jbl about it

    Unless of course they screwed up at the factory and have a reverse polarity on the magnet. We know this to be the case in maybe 2% of the speakers..., present company included. Shiite happens.

    It's pretty simple, really.

    A question was asked, and I responded with the correct answer. Analysis paralysis is futile. Just accept it and move on.

    good morning thanks for the answer..
    I can not find confirmation by testing my 123a-1 with what you wrote.
    no paralysis of the analysis

    I have a problem and I would like to solve.
    thanks again luigi

    I finally ascertained that the woofer 123a-1 and positive transducer
    and the 2213h and a negative transducer.
    I ask you having foolishly replaced the 2213h with the 123a-1 in my 4312 first series (with original crossower
    )What should I do ? reverse the wires behind the 123a-1?
    to have a right crossover ?

    thanks for the help luigi
