Speakers are almost always a better price/performance value in overall SQ than soundbars. And if this is for sitting at your computer, then having separate speakers means you'll be able to angle/position them for better imaging/sound.
A subwoofer does help for movies.
Do you have a local Guitar Center? They have various studio monitors, including Adams. Worth giving a listen before you do further research/decision making.
How about passive speakers and a small t-amp?...
