What does each channel do in a surround sound home theater setup?
The goal of surround sound is to immerse you in the experience of your favourite movies!
The front speakers do most of the heavy lifting handling the majority of the audio signal.
The center channel focuses on dialog when facing a character.
The surrounds handle sound that happens "behind the camera"
Last, the subwoofer handles the low end frequencies the other speakers can't and delivers and adds body to the sound.
