From what I recall, they had a reputation for being excellent back in the day, but that was in the nineties. I'd imagine "lower end" speakers of current design ought to be better. When my son gave me the refurb pair (originals not the 2s) I got for the Q630 setup in his room back to me about four years ago, he said they really weren't all that good as compared to what he had been using with his TiBook.

That said, other than reductions in size and weight while maintaining performance levels, I'm not sure how much speakers could have improved over the years.
