Why and how to calibrate your hi-fi or home theater system


The automatic calibration of a home theater system (or a hi-fi system) aims to optimize its sound reproduction. It primarily allows you to adjust three factors:

  • the equalization of the speakers and subwoofer,
  • compensating for any asymmetrical placement of the speakers when the geometry or furnishings of the room require it,
  • the correction of resonance induced by the acoustic characteristics of the listening room.
