If by Bose-like you mean small form factor its hard to beat Bose because small form factor is Bose's biggest strength. Here are a few options that could work in your case but I think that in most of these cases you would be looking at larger speakers and subs to get better performance.
The usual substitute for Bose is Cambridge Audio Minx Min 12 or 22. Alternatively, the Gallo A'diva (among others) is quite small and has many finishes to choose from. If saving money is your thing, then look at the Boston Acoustics Soundware (on close-out at accessories4less.com).
