Axiom Home Page Forums General Discussion Technical Questions speaker phase

I guess I'm a little confused by your question, red is red, black is black, positive (+) is usually associated with red, and negative (-) associated with black. Just like the jumper terminals on a car battery. I would not buy a Calibration CD, just to check for polarity, would be a waste of money. Speaker wire can also be purchased with a color strip on on side, so it is easy to make sure you have everything hooked up right.
