What does reversing polarity on a subwoofer mean?
Reversing polarity on a subwoofer refers to changing the direction in which the electrical signals are sent to the speaker. This can be done by swapping the positive and negative leads of the subwoofer’s connections. When the polarity is correct, the subwoofer moves in sync with the other speakers, producing balanced and cohesive sound; when reversed, the subwoofer may produce out-of-phase sound, leading to a loss of bass and overall sound quality.
The polarity of a subwoofer is crucial for delivering the intended audio experience. Correct polarity ensures that sound waves from the subwoofer and main speakers reach the listener at the same time, reinforcing the overall effect.
