Hi Ian,

I did the 9 volt battery test and the speaker is now confirmed to be wired backwards. When I put + to +, the driver moves in. When I put + to - the driver moves out. I have banana plugs on my speaker cables and Red is +, Black is -, both sides.

Video is here: https://ufile.io/tyjverim

And here’s a picture of my cable.



It's no big deal, I don't mind flipping the wires around!
