It’s all in the timing, or rather, the phase

- [Narrator] When the surface of a speaker beats the air, it starts from a resting position, moves out to increase the air pressure, then moves back through its resting position into the speaker cabinet to create low air pressure before returning to its resting position. And that whole movement is one full cycle. Professional studio monitors can complete tens of thousands of cycles per second. The precise timing is called the phase. Because the movement is cyclic, it can be measured in degrees just as you might measure the angle of a hand moving around a clock. Zero is the resting position, 90 is fully out, 180 is back to the resting position, 270 is fully into the speaker cabinet and then 360 is back to the resting position again. Ideally to maximize amplitude you will want two speakers in a stereo configuration to move out and in exactly in sync. If the speakers are producing the same frequency at the same amplitude, for example if they're producing a mono signal shared equally…
