Setting the correct phase on an active subwoofer is an essential step in achieving optimal sound quality in your stereo speaker system. This article will guide you through the process of setting the correct phase on your subwoofer and ensure that it is working in sync with your main speakers.
First, let's define what we mean by the phase. The phase refers to the timing relationship between the subwoofer and the main speakers. In a stereo system, the subwoofer should be in sync with the main speakers, meaning that the sound waves produced by the subwoofer should be in phase with the sound waves produced by the main speakers. If they are not in phase, it can result in a loss of bass response, and the overall sound quality will be compromised.
Here are the steps to set the correct phase on your subwoofer:
- The first step is to play test tones or some bass-heavy music through your main speakers and subwoofer. You can use a slow bass sweep between 30Hz and 120Hz. Important is to cover the crossover frequency you set. With music, we recommend something electronic with a recurring bass. Daft Punk - Technologic for example works great.
- Adjust the phase on the subwoofer in small steps. Start with 0 degrees and work up slowly.
- Listen to the test tones or music and pay attention to the bass response. If the bass sounds fuller and more robust, then you have successfully set the correct phase on your subwoofer. If the bass sounds weak or thin, you need to tweak it till it sounds louder.
You can try different music genres to verify your results.
Have fun listening!
