Technology / Home Audio / Phase: Refers to the timing relationship of two or more signals or sound waves. It's especially important to be sure that your stereo speakers are playing 'in phase.' This means that the drivers (woofers and tweeters) of your right and left speakers are moving in and out at the same time. If your stereo speakers are 'out of phase' ?€” that is, with one set of positive and negative leads reversed ?€” you'll hear significantly less bass, and instead of producing a strong center image, the sound tends to stay localized at the speakers. To learn how to be sure your speakers are in phase, check the Home Speakers FAQ).
