When it comes to setting the phase of your subwoofer, there are a few things that you need to take into account. First, you need to make sure that your subwoofer is in line with the rest of your speaker system. This means that the subwoofer should be placed at the same distance from the listener as the main speakers. Secondly, you need to make sure that the subwoofer is facing the listener. This will ensure that the sound waves from the subwoofer reach the listener directly, without being diffused by furniture or other objects in the room.
As for what phase your subwoofer should be set to, there are two schools of thought. Some people believe that setting the subwoofer to 0 degrees (or in-phase) produces the best results. This means that both the main speakers and subwoofer are producing sound waves at exactly the same time. Other people believe that settingthe subwoofer to 180 degrees (or out-of-phase) produces better results. This means that while one speaker is producing a positive sound wave,the other speaker is producing an equal but negative sound wave. These twosound waves cancel each other out when they meet, which creates a morepunchy bass response.
Ultimately, it comes down to personal preference as to which phase setting sounds better to you. We recommend trying out both settings and seeing which one you prefer.
