Good speakers for a low budget

Used was the idea. As far as specifics go, the speaker should be musical (she likes to dance), not too bright, and they should sound relatively good outside their sweet spot (she likes to listen to music while cleaning). Thank you for your suggestions.

No, she's definitely not an audiophile. I posted the question because I was trying to provide her with suggestions other than Bose which she was actually looking at. Musically, she mostly listens to light rock, new age, pop (generally upbeat with synths), classical, and a little folk. As far as the system is concerned, this probably won't be very helpful, but there's a sony str-de895 receiver, a pioneer pd-m501 cd player, and unlabeled PSB speakers manufactured in the early 90's (I think they might be the alpha B's). She was going to replace the system component by component as she acquired the funds and was going to start with her cd player, but I suggested that she upgrade the speakers first because that generally leads to the greatest amount of improvement. I believe the receiver puts out something like 100 watts per channel and the receiver should be able to drive the speakers for the time being, although I guess the alternative is to save up and buy speakers and an integrated amp in one shot.

She knows little about audio and wanted to replace the cd player to improve the sound of the system which has a really small sound stage and seems to drown out a lot of the high frequencies (female vocals, violins, etc. can barely be heard in the presence of male vocals, drums, etc.). I suggested the speakers, which are definitely not the weakest link, because changing speakers typically has the most drastic effects on the sound of an audio system. I hooked up my North Star cd player in place of her cd player today to see whether or not it would make a difference and, surprisingly enough, it actually made a world of a difference. More detail, tighter bass, etc. I guess there is always the option of spending the same money on an integrated amp or a cd player such as the rotel rcd 1072.
