Imaging refers to the aspect of sound reproduction involving the perceived spatial locations of the sound source(s), both laterally and in depth. An image is considered to be good if the location of the performers or acoustic material can be clearly located in space. A subwoofer or loudspeaker's ability to place an instrument, sound effect or other audio content with a sense of size, location, depth, distance and directionality in the sound field. A speaker with superior imaging will allow you to hear a bass guitarist playing in the front left of the stage, vocals coming from directly in front of you or action happening just off screen in a home theater surround sound system. Imaging allows your brain to place exactly where the sound is coming from spatially to create a more immersive and convincing "like-being-there" home audio experience.
