Just curious on why people do that,does it make it louder or somthing? ill put a link to a video to show you what i mean...http://www.youtube.com/watch?v=-BAnhfviqfA&feature=related

And if they do do it to make it louder then i dont really understand,because i thought air flow was a good thing for speakers...
