I KNOW the wire is correct as far as polarity / phase goes. My point was, since the speakers come from different manufacturers, do they have a STANDARD way to mark the colors that will positively assure correct polarity throughout the 7 or 8 speakers? That's why I was looking for a test of sorts.

I'll have to check my Starwars dvds for the test mentioned in snakeyes post.
