“#The new iMacs have \u2018force-canceling\u2019 speakers \u2014 here\u2019s what that means<\/strong>”<\/p>\n

App<\/a>le loves throwing around buzzwords in product reveals and spec sheets, and one that caught a few eyes was the use of \u2018force-canceling\u2018 in the new iMac\u2018s sound systems. Apple claims these are the best speakers in an iMac yet, but what does a force-canceling woofer actually mean? Is that some kind of Jedi fighting space dog?<\/p>\n

It\u2019s nothing quite as sci-fi as Star Wars. Force-canceling woofer arrangements are fairly common in high-end audio, and while they are far from a guarantee of good sound quality,\u00a0they do theoretically offer some benefits.<\/p>\n

The basic idea behind force-canceling woofers is to eliminate unwanted vibrations by having two woofers firing in opposite directions and perfect unison.<\/p>\n

Remember Newton\u2019s third law? For every action, there is an equal and opposite reaction. When a woofer moves, the \u2018reaction\u2019 has to go somewhere \u2014 usually as stray vibrations in the woofer\u2019s enclosure.<\/p>\n

These vibrations can lead to the enclosure rattling and radiating unwanted sound. In large drivers, like those in a subwoofer, it can even cause a speaker to move around the floor. By placing another woofer that fires in the opposite direction, the reactive forces are able to largely cancel each other out.<\/p>\n

So why would you want force-canceling woofers in your gadegts? Well, if you\u2019ve ever felt like your computer or phone sounds muddy and rattles when playing bass, these extraneous vibrations are often a culprit.<\/p>\n

In theory \u2014 <\/em>nobody has actually heard the new iMac yet \u2014\u00a0the configuration could help prevent these artefacts and minimize distortion.<\/p>\n

In hi-fi speakers, you can also deal with vibrations by creating a dense cabinet with dampening materials or carefully chosen geometry, but one can\u2019t expect the same from a multi-function device like the iMac.<\/p>\n

None of this guarantees the new iMac will actually sound any good, but hey, now you know. For a more technical explanation \u2014 and to see what a force-canceling setup looks like in some hi-fi speakers, you can check out the below explainer by Soundstage Network and audio researcher Jack Oclee-Brown.<\/p>\n
