example, a pile of boxes. Do not try to guess ear positions, as this introduces
measurement errors.
Pick an ideal central location where all speaker output signals converge.
Use a tape measure to measure the distance from each speaker to the convergence

speaker or from halfway between the tweeter and the woofer in a two-way
speaker. Measurements to the convergence location should be at ear height.
When the distances to every speaker have been measured accurately, select the speaker
that is farthest from the convergence location and use that distance as a reference

Calculate the delay distance for each speaker, where:
Delay Distance = Farthest Speaker Distance - Individual Speaker Distance
