Another vote for KRKS, I actually have the ST-6's which are basically passive higher-end Rokit 6's, and sound incredible.
Having been and still am an audiophile and having listened to some very high end sound systems (Bowers and Wilkins for starters.), I can attest to the fact that Bose makes quality products.
Yes, there, its out there, because quite frankly, I find it to be true.
They're not the best, far from it, and their home theater systems are overpriced in temrs of just sound quality, but as a whole PLUS having second to NONE customer service (They treat you like a friggin family member) makes they're products prices slightly more reasonable.
Now, owning none at the moment but having owned a pair of Companion 3's series I and series II: I think there's honestly really no other competitor in the price-range their offered in, Bose really made an excellenet set of active, nearfield speakers (and in some cases even, monitors).
So unless you've got the cash for the AudioEngines (but for the 2's would be far lacking bass vs the Bose) or higher end KRK setups, the Bose C3 Series II's or if you'd rather have surround sound and a dedicated USB sound card built into the speakers (pretty nice, really), the Companion 5's.
My .02 cents, but for the price range (I know like the opposite of most Bose arguments) I think the Companion series as a whole pretty much can't be beat. They can sound a little tinny sometimes (not tiny, well maybe tiny, but harsh), but with some physical adjustment they usually are spot on and impressively revealning speakers.
EDIT: Actually, I forgot, but these would probably topple the Bose or any other offerings in its price range:

As opposed to what the first comment innacurrately writes, these speakers from what I can gather from reliable sources of people who actually know what they're talking about, these ARE audiophile quality, at least relatively, given they're price range.
Supposedly game studios are using these for mastering, too. I haven't heard these, but these are the only speakers I'd remotely consider trying next to Bose or, for a higher price, KRKs. (or AudioEngines or any quality studio monitors)
