Dual voice coil (DVC) speakers provide flexibility in usage because they can be wired to different impedance levels. Depending on the type of amplifier you are using, or the number of speakers in your system, the impedance, or resistance, of your speakers can be a crucial element in how the speaker and the audio system perform. By following a few simple steps, you'll be able to wire your speakers like a pro.
Instructions
1. Examine your dual voice coil speaker. Dual voice coil speakers have two sets of speaker terminals, one to drive each voice coil. Depending on how you connect speaker wire between them, you can double the impedance (resistance) of the speaker, or halve the impedance (resistance) of the speaker. For example, if your speaker has two 4-ohm voice coils, you can wire the speaker to a resistance of 8 ohms or 2 ohms. Check the speaker's documentation to be sure what the impedance of the voice coils is.
2. Connect speaker wire between the terminals of the amplifier and the first set of terminals on the speaker--positive (red) to positive, negative (black) to negative. Then connect speaker wire between the first set of terminals and the second set of terminals on the speaker--connect the positive to positive and the negative to negative. This will double the impedance of your speaker.
3. Connect speaker wire between the terminals of the amplifier and the first set of terminals on the speaker--positive (red) to positive, negative (black) to negative. Then connect a single piece of speaker wire between the positive terminal of the first terminal set and the negative terminal of the second terminal set. Complete the circuit by connecting a piece of wire between the positive terminal of the second terminal set and negative terminal of the first set of terminals. This will halve the impedance of the speaker.
