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

But this pictures say different.

My XO wiring is the same like this picture i found in my research here:

How to connect the Blk/green and green wire on the LE14A ?

I only become more confused by my research :blink:

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.

yeah only think to do is use my ears to find out the right wiring.

Green to red terminal and blk/green to black terminal
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.
