Registered. Wiring speakers "out of phase" will "destroy" imaging — sounds that should "center" between the two main speakers might sound very diffuse, instead — and can cause the apparant sound level to be diminished (weakened bass, for example).20 Dec 2001
How do I know if my speakers are out of phase?
When you phase a speaker, the idea is to have both speakers moving in the same direction at the same time. If your speakers have the positive side of the speaker wire connected to where the negative should be, they will be out of phase.
What happens when two speakers are out of phase?
Two initially in-phase speakers interfere destructively when the path difference from them to the listener equals an odd multiple of half-wavelengths. Two initially out-of-phase speakers interfere constructively when the path difference from them to the listener equals an odd multiple of half-wavelengths.
What does out of phase sound like?
Since phase cancellation is most apparent in low frequency sounds, the audible result of out of phase monitors is typically a thin-sounding signal with little or no bass sound. Another possible result is that the kick drum or bass guitar will move around the mix, rather than coming from a single spot.
What happens if speaker polarity is wrong?
Reverse polarity leads to phase cancellation when more than one speaker is being used. Sonically, this causes certain frequencies to be canceled out and has an undesirable effect on the audio quality. Wiring speakers backward won't cause any damage to the devices, nor is it a dangerous practice.
How can you tell if speaker polarity is correct?

Does Left Right speaker matter?
But does it matter? For some types of audio, it doesn't matter all that much. There isn't really any fixed left and right in electronic dance music for instance. The producer might prefer a certain synthesiser whoosh to come from the left, but it doesn't matter to the listener whether he or she hears it from the right.
Can speakers cancel eachother out?
A noise-cancellation speaker emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) relative to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out – an effect which is called destructive interference.
What happens when waves that are out of phase combine?
Destructive interference occurs when the maxima of two waves are 180 degrees out of phase: a positive displacement of one wave is cancelled exactly by a negative displacement of the other wave. The amplitude of the resulting wave is zero.
