Determing polarity on speaker
by sviatapolk - 6/6/12 5:12 PM
I was just given a classic stereo receiver and some old fashioned Polk 7 speakers.
The speaker terminals are not, however, marked either by color (red/black) or polarity (+,-) whereas the stereo receiver is. The speaker terminals are marked 1 and 2. How can I know if 1 is the red/+ or if 1 is the black/-?
I've tried them both ways and I can't hear a difference.
