i have been using AL MX5021 since 1 year and trust me its an awesome set of 2.1,great clearity.dont have much idea if there is better 2.1 setup in that price range but MX5021 is one heck of a speaker.
MX 5021 is a 2.1 setup, not 2.0. Please do a search in the forum before starting a thread, there is a dedicated thread/ guide on how to mod the MX 5021 (which is pointed in the above posts), also there are lot of discussions available in this topic.
