Budget? And do you want a full active system, where you just plug in a mini headphone jack or rca? If so, there can be quite a few choices
On the expensive side, there's the Focal Bird range.
On the cheap, there's Acoustic Energy's AEGo series.
Pwede din KRK active monitors paired with one of their active subs. The Audio Engines suggested here are a good choice as well.
