Thread: Reversing Polarity On Subs |

I was wondering if someone could tell me what exactly does the "reverse polartiy" function on some head units and amps actualy do to the sub? In my setup if you reverse the polarity, the sub seems to have a much deeper sound to it. Kind of hits harder and echoes less. Are there any drawbacks, will it strain the amp? |

the function is usually used to make a pair or multiple subs hit in the same direction. reversing the polarity, simply reverses the direction in which the subs hit (i.e. back and forward to forward and back.) pairs of subs for example, hit better (sound MUCH better) when they move in the same direction. youll also find that some brands of subs will sound better going the opposite way even as a single sub... its up to you really |

So reversing doesn´t damage the sub? Does it reproduce the soundwave correctly? |

reversing polarity inverses the sinewave, so that the signal is 180 degrees out of phase.
this is used for phase correction depending on how the subs are positioned.
if it sounds better in the shifted phase position, leave it there.
