![]() Now, you might want to know what happens when they sync- Source: That means the incoming signal is synced with that of the other speakers around the room. When the subs are in a normal phase, it’s called in-phase. When you buy a brand-new subwoofer, the phase will be usually set to normal. In order to find out the best phase setting for subwoofers, we need to take a deeper dive- Normal Phase (0 Degree) However, before we come to a conclusion, let’s learn about the phases of a subwoofer.Īnd also, how it affects the sound quality. ![]() Understanding the reverse or normal phase of a subwoofer is very simple. But be careful! It can also affect the longevity of your subwoofers! On the other hand, setting the subwoofer to reverse can provide louder sound. Normal phase subwoofers are also vulnerable to having noise. You should prefer normal subwoofer phase for more clear sound experience, but at the cost of audio distortion. Should the Subwoofer Phase be Normal or Reverse? Just try it out and find your sweet spot for your best audio experience. That means you can set the subwoofer to any phase between 0 and 180 degrees. These controls have more options along with 0 and 180 degrees. ![]() Some subwoofers have ‘variable’ phase control. Usually, 0 degrees means a normal phase, and 180 degrees means the reverse phase of the subwoofer as we said earlier. You can switch between these two phases using the controller. When there are 2 subwoofers, the 1st one is reversed When there’s only 1 subwoofer in the system If both present in the opposite direction of the same room If both present in the same room in the same direction Let’s have a look at the quick difference between subwoofer phase normal and reverse. Now, if you take a close look behind your subwoofer, you’ll notice a switch that is labeled ‘phase’ and control with degrees 0 and 180. It’ll help your subwoofer to integrate with the other loudspeaker in the room. You should use subwoofer phase when you want to add electrical delay to your subwoofer. That is mainly what causes the delay of the signal transmission. This explains the noise cancellation effect.Īnother fact, the polarity of the subs also changes if you switch the phases. This means the wavelength of other speakers does not interrupt the wavelength of the subwoofer in the reverse phase.īut in the normal phase, the wavelength gets interrupted. You can see that the difference between the frequencies of the normal and reverse phase is not much.īut at one point, the frequency in the normal phase decreases almost to zero.Īnd at that point, the frequency of the reverse phase is still high. Here in the graphs, a speaker is tested with normal and reverse phases separately. The one at the bottom is the frequency of the subwoofer reverse phase. The graph on top is the frequency of the subwoofer normal phase. Here’s a graph explaining the audio frequencies of the normal and reverse phases of a subwoofer. However, at high frequency, the sound effect is not as subtle. Delay can sometimes help the speaker integrate better with the other speakers in the room.sīut if the subwoofer is solo, the phase shift doesn’t make any audible difference. The 180 degrees phase setting reverses the subwoofer polarity. You can tune the phase control from a range of 0 to 180. The phase control of a subwoofer allows the speaker to delay incoming electrical signals by the conductors.
