driver polarity
Hi everyone, I have a question that might seem dumb, but I'm putting together my first DIY project, and I can't quite figure out my driver's polarity, which is + and which is - ?!? I don't want to power them with the wrong polarity... Can someone help me with this?
Thanks. |

Speaker polarity
Place a small torch battery, AA size 1.5v will do, across the 2 terminals of the speaker for a second or two. With the + terminal of the battery on the + terminal of the speaker, the speaker cone will move forward. With the + battery terminal on the - terminal speaker, the cone will move inward.
(Also a quick test to see if a speaker is blown ) |

Touch a 1.5v battery to it, whichever connection pushes the cone forward is the correct one.
