Is the red speaker wire positive or negative?

These terminals are also almost always color-coded for easy identification: The positive terminal (+) is typically red, while the negative terminal (-) is typically black. Note that some speakers are bi-wire capable, which means the red and black terminals come in pairs for a total of four connections.
A.

Is the large speaker terminal positive?

Generally speaking, the positive terminal is usually on the left when the speaker is facing up. On our neodymium models, this is opposite. The positive terminal is marked in red on the right when the speaker is facing up. If the cone moves in, the positive battery lead is connected to the speaker's negative terminal.
  • Do speakers have polarity?

    Depending on how a speaker has been wired internally or connected to the amplifier, it will either move in or out in response to a given input signal. As long as a single speaker is concerned, this direction has no influence on the perceived sound. When polarity is wrong, the speakers will be out of phase.
  • Why is my Bluetooth not working?

    On your iOS device, go to Settings > Bluetooth and make sure that Bluetooth is on. If you can't turn on Bluetooth or you see a spinning gear, restart your iPhone, iPad, or iPod touch. Make sure that your Bluetooth accessory and iOS device are close to each other. Turn your Bluetooth accessory off and back on again.

B.

Is the marked speaker wire positive or negative?

The solid/dashed lines on wires like the ones pictured in your question are used to indicate polarity e.g. for the "wall wart" power supplies. Usually* the wire with the white stripe or the dashed lines carries the "positive" (+) end, while the other, unmarked wire carries the "negative" (-) end.

  • Which wire is positive in an extension cord?

    This means the plug has a small blade for the hot wire and a wide blade for the neutral wire, and the wires feeding those blades should not be reversed when you put a new plug on. Always use a polarized plug for a lamp, extension cord or any other cord that's polarized to begin with.
  • What color is positive or negative?

    In DC circuits, the positive pole is usually marked red (or "+") and the negative pole is usually marked black (or "−"), but other color schemes are sometimes used in automotive and telecommunications systems.
