Maybe I'm not looking close enough, but which terminal is positive and which is negative?

Also, black wire positive?

    There's often a red paint mark on the + terminal of speaker drivers. If that's gone, connect a battery to the driver, see which polarity makes the cone move outward. I was always instructed to use a 9-volt job, but others recommend an ordinary AA, C, or D.

    Black wire is likely positive, since Polk tends to use white as the color-code for negative.
