in Basic Hookup/Wiring Questions
I have just received two rdo 194 tweeters in order to replace the old sl-2000 tweeters that are in there. I am a bit confused on how to wire them. The rdo-194 has a terminal that is painted red which i assume is the positive. Where I am getting confused is when looking at the old tweeter. It has a black and white wires connected. I assume that the black means negative and the white is positive. But there is a cross mark on the sl2000 right next to the terminal where the black wire is connected. So is the black wire positive?

    Yes black is positive. In my old alarm installing days all low voltage was red+ black -. When we were dealing w/ Cat-6 the solids were positive and the stripes or dashes were negative. Why Polk did that who knows but they did go through a lot of colors when the models got bigger. Just a guess.....
