They're only 3" woofers, fixed, lossy grilles, and a thinnish plastic housing, so don't expect miracles. Deep bass will be completely absent, and even mid-bass will be partially missing, and what's there will be blurred by cabinet resonant noise.
In a small bedroom on a desk they could sound "good", _in theory_, if not pushed hard, but they're just too small to really excel. The real question is whether they sound good enough to fork over US$320+, and I think the odds are stacked against them, design-wise.
Also there's a note in the copy to add a subwoofer if you want bass, but there's no sub out on these, so you'd need a sub with its own crossover inputs and outputs to do so, and not all subs have those, especially the cheaper ones.
For me I'd rather spend $400 on some used, larger Genelecs (or Mackies, Adam, even KRKs...).
