This standard aims to create a\u00a0reliable testing method and a rating procedure to let manufacturers and customers\u00a0compare powered subwoofers in an simple way.<\/p>\n<p>The CEA standard is built upon a tone burst sequence performed at various frequencies and levels, until a certain distortion threshold is reached. While the test is\u00a0intended for powered subwoofers, the same burst test can be applied to a broad case\u00a0of electro-acoustic devices such as non-powered subwoofers drivers, tweeter drivers\u00a0and compression drivers.<\/p>\n<p>Despite being available since late 2006, the standard has only recently gained popularity in the audio community, at least this is what we can see from the support\u00a0requests from our clients base.
