I agree with your recommendation in Adam’s case, but to nitpick slightly: great sound, absolutely, lows, yes, probably enough of them depending on your definition of “low.” E.g. my Genelec 8020 4"ers roll off at 62Hz. This is enough to sound low but not enough to provide any of the fundamentals we hear at a live performance, which extend down to 20Hz (or lower, if you include the frequencies we can feel). To get down there you need multiple drivers or a single driver in the 12"-15" range and it’s those frequencies, and not the higher ones, that are influenced by the dimensions and speaker position in any room, not just small ones–years ago Roy Allison designed a whole line of wide-range speakers that took advantage of this fact. Setup of a full-range system with an acoustically flat response at the listening position is quite tricky and almost impossible to accomplish “by ear” in any space and especially at a computer station, and that, if nothing else, is why you should limit yourself to smaller speakers and, probably, stay away from the ones with “subwoofers.”
And if you want really great sound, I still say, Go for a pair of Genelec 8010s, 3"/74Hz.
