Dont get me wrong its not exactly a 10" sub or anything. Have a look here in the gallery and see what i mean. Its just ever so slightly better than not having it but still better.
Well, it's definitely bigger than the driver in an IEM or earbud. LOL
But certainly such a gimmicky marketing ploy, that I'm not surprised that you are having problems with the headphone output. If that audio setup on the machine were that good, they wouldn't have to try to sell people on the misleading idea that there is a useable subwoofer on the bottom of the laptop.
