    Hello

    Not sure?? Some info in here but I don't think it covers polarity for the Le5-2. Look on the driver techsheets.

    Io have Le5-2 and it is Negative. Sure

    Le5-12 in driver techsheet write :
    "positive voltage to male teminal give forward cone motion"

    I not are sure that LE5-12 is positive...no sure....I think not....
    how i can verifity those....?

    i have make a big stupid error swiched to Le5-12 to LE 5-2 ,,,in my 4312jbl and now I don't know if the crossover is correct for le5-2 in terms of polarity.
