Hi, I just received my new Macbook Air as a replacement of my late 2010 Macbook Air. I noticed a real bad performance of the speakers and in comparison to my old MBA they are just terrible. Not in terms of volume but in terms of sound quality and "richness" of the music. Are the new speakers much worse or are they not working correctly? Should I contact Apple for a replacement? Otherwise I'll just probably return it because the sound is just awful.
