i'm actually glad the ASD's had a decent internal speakers.Personally, I think Apple should have abandoned internal speakers on the ASD and created a matching pair of externals.
I'm sorry, but if you have any experience with audio, the ASD speakers are not very good at all. Even a fairly inexpensive set of speakers or headphones will make the point easily.

i was able to trash my old external desktop speakers and add the ASD to work with my existing 30" monitor for a dual monitor setup
far better sound quality and no more thumps whenever the flourescent table lamp was turned on or off.
