Incorrectly wiring speakers can hinder optimal sound performance. Learn about the effects of reversed speaker wires and the correct way to connect them for quality sound output.
What happens when speaker wires are reversed?
Speaker wires, also known as audio signal cables, establish the connection between speakers and power amplifiers, receivers, etc., transmitting signals between devices. They serve as vital links enabling seamless communication within audio setups. Reversing speaker wires can result in the following signs:
Image and sound desynchronization
For a perfect entertainment experience, the visuals on the TV screen and the audio from the speakers must synchronize. Reversed speaker wiring may cause the audio to precede the visuals, significantly impacting your viewing and listening enjoyment.
Lack of bass sound
One consequence of incorrectly wiring speakers is the loss of bass frequencies in the music. In this scenario, the phase of the audio signal is inverted, causing bass waves to possibly overlap with signals from other frequency ranges, resulting in imbalanced and disconnected sound.
Incorrect speaker wiring can lead to the elimination of bass frequencies
High-pitched sound distortion
Reversing speaker wires not only affects bass frequencies but can also cause high-frequency sounds to distort when the speakers are in operation.
Speaker malfunction or damage
Certain speaker types like portable speakers or karaoke speakers, which utilize high-power amplifiers, may experience circuitry issues or damage when speaker wires are reversed. For compression drivers or high-voltage speakers using standard power amplifiers, they may still function initially but could abruptly cut out after around 10 - 15 minutes of use. For speakers with transformers, reversing speaker wires could lead to transformer burnout.
2. Signs of incorrectly wired speakers
Having explored the effects of reversed speaker wiring, how can users identify incorrectly wired speakers? Typically, incorrect polarity of speaker wires can cause the amplifier to overheat during speaker use or result in automatic shutdowns after a period of operation.
3. Guide to Proper Speaker Wiring
Before starting the speaker wiring process, users should carefully observe to determine the correct positive and negative terminals on both the speakers and the amplifier. It's also essential to understand the speaker's impedance rating to ensure proper connection to the corresponding impedance-labeled port on the amplifier (usually marked as output and additionally labeled with 8Ω, 16Ω, etc.).
For speakers with two wire strands, the red wire is typically the positive terminal, while the black wire is the negative terminal. On the amplifier, the negative terminal input is usually black, and the positive terminal input is red.
Note the positive and negative terminals when wiring speakers to amplifiers
To connect speakers to the amplifier, attach the positive speaker wire to the positive terminal of the amplifier, and the negative speaker wire to the negative terminal of the amplifier. After connecting, turn the volume knob to 0, then turn on the speakers and gradually increase the volume to test the sound. If the sound plays normally and no issues occur as described above, it means you have successfully wired the speakers to the amplifier.
