    Need help from L-220/222 owners

    Need help from L-220/222 owners and other wise people

    After som research about JBL L-220 and the polarity of the LE14A i cannot find the real answer of that.

    If i test the woofer with a battery, and connect plus to red terminal the woofer is going IN

    The technical manual say: Green to red terminal and blk/green to black terminal

    I don't know which drawing is correct. But in the past when I've connected the woofer with the wrong polarity, (on my PT800, PS1400 setup) the effect was obvious. Vocals sounded hollow and the bass was thin. Swapping the woofer wires made an obvious improvement.

    This is standard in virtually all JBL speakers with the green and green/black wires. I wouldn't deviate from this. Unless someone has swapped the wires on the XO board, there's no reason to change it.
