Abstract
A method for stereo loudspeaker placement consisting of applying an acoustic signal having equal amplitude components spread over at least a portion of the audible sound spectrum to a set of stereo loudspeakers to create an acoustic signal, measuring the combined sound level of the acoustic signals at the principal listening position, and adjusting the location of the loudspeakers to ensure that they are acoustically-equidistant from the principal listening position.
