Subwoofer Phase 0 or 180? [Detailed-Guide]

One of the most commonly asked questions about subwoofers is whether a phase 0 subwoofer is good or a phase 180 subwoofer.

To answer this question in great detail, we have compiled this complete step-by-step guide, in which we have answered the question of whether you should get a phase 0 or phase 180 degrees placement.

That being said, let’s jump right into the matter and check out the details.

What is Phase Control in the Subwoofer Setup?

The phase control in the subwoofer means the adjustment of the subwoofer and the speakers in layman’s language. This becomes super important while setting up the subwoofer, and the speakers for the best possible sound performance.

Phase control in the subwoofer allows you to create an electrical delay in the sound of the subwoofer, allowing you to get the proper performance.

There are mainly two types of phase control in the subwoofer, and choosing the right type of phase control in the subwoofer setup allows you to better integrate the subwoofer with the speakers to create a mesmerizing sound experience.

You can either choose phase 0 or phase 180, and it depends upon the subwoofer and the speaker’s positioning.

Phase 0 (Normal Phase) in Subwoofers

Phase 0 also known as the normal phase is the default plane on the subwoofer. In this phase, there is no delay in the output of the speaker, and the subwoofer.

This phase is perfect for times when you the speaker, and the subwoofer are in the same plan, meaning that the subwoofer and the speaker would produce sound in the same sequence without any delay.

Phase 0 is the most commonly used phase, and provides accurate sound when the subwoofer and the soundbar are placed in the same plane.

Phase 180 (Reverse Phase) in Subwoofers

Phase 180 which is also known as the reverse phase provides you with a delay in the sound of the subwoofer and the speakers.

The reverse phase on the subwoofers is perfect for times when the subwoofer and the soundbar are placed opposite to each other.

This creates a delay in the sound and makes the sound emerge providing you with better sound performance without any interference. 

Variable Phase in Subwoofers

Some subwoofers do come with variable phase settings that allows you to transition between phase 0, and phase 180 for more diversified sound.

The variable phase is perfect for times when you do not want to have any messy sound through the speakers, and the soundbar.

Phase 0 or Phase 180 Subwoofer

Most of the subwoofers come with two-phase options, either phase 0 or phase 180 degrees. The phase configuration of the subwoofer depends upon the positioning of the subwoofer and the speakers.

If the subwoofer and the speaker are in the same direction, then it is better to have the phase 0 integration, as it projects the vocals, and the low-frequency response better.

Moreover, as both of the devices are in the same direction, it creates a better sound effect.

On the other hand, if the speakers and the subwoofer are placed opposite to each other, then you need to set the subwoofer on phase 180.

In this way, you create an electrical delay in the sound of the subwoofer, which means that the speaker and the subwoofer won’t create any sort of interference with each other.

Car Subwoofer Phase 0 or 180

Just like the normal home theatre subwoofer, if your subwoofer and loudspeaker are facing the same direction, then you should use phase 0, while if your car’s subwoofer and the loudspeaker are in the same direction.

On the other hand, if your subwoofer and speakers are placed opposite to each other, then you should use phase 180, which creates an electrical delay in the performance of the subwoofer.

Dual Subwoofer Phase Setting

When you are using a dual subwoofer one thing that you need to have in mind is that you need to have the same phase settings on both subwoofers, otherwise you can have worse performance than the single subwoofer setup.

Hence, assure you are using the same phase settings on both of the subwoofers.

Klipsch Subwoofer Phase 0 or 180

Arguably the most asked question about the Klipsch subwoofers is the phase settings, whether you should get the phase 0 or phase 180 subwoofer. 

The answer to this question is not in black or white, rather, it depends upon the situation.

If the subwoofer and the speaker are in the same direction, then you need to have phase 0 enabled, otherwise you need to have phase 180 on your subwoofer.

The reason behind this is quite simple. If the subwoofer and loudspeaker are in the same direction there should be no delay, as both of the components should work in harmony.

On the other hand, when the subwoofer and the speaker are facing opposite directions, there would be a delay, otherwise, the frequencies from the opposite side can mess with each other.

Frequently Asked Questions (FAQs)

Should I Set Phase 180 or Phase 0 on Subwoofer?

It depends upon the positioning of the speaker, and the subwoofer. If the subwoofer and speakers are in the same direction, then you need to put the subwoofer on phase 0. On the other hand, if the subwoofer and the speaker are put opposite to each other, then you need to have phase 180 enabled.

What Does Phase Control Do in a Subwoofer?

The phase control on a subwoofer would create an electrical delay that reduces the interference between the subwoofer and the soundbar.

Is There Any Difference Between the Phases of a Subwoofer?

Yes, there is a lot of difference between the phases of the subwoofer. If the subwoofer is set to the wrong phase according to the adjustments, it can make interference with the sound.

Conclusion

Phase setup plays an important role in the sound performance of the subwoofer. People always get confused about whether they should choose the 0 phase or the 180 phase.

Thus, we have compiled this in-depth guide, in which we have thoroughly discussed what phase is, and whether phase 0 is good or phase 180 is good for the ultimate sound performance.

So, you can choose the right subwoofer phase for the best possible sound.
