The article gives an answer to "louder" question but not "better" one. As far as I have understood the screen after the text, Mac speakers are not 1-way but at least 2-way (every channel contains a speaker for bass and a speaker for higher frequences). That is the answer about quality of sound, there are no speakers which can play both highs and lows in nice quality.
