I have a lot of thoughts on this, but first . . .
GO WITH WHAT you like! Go with what sounds best to you in your price range.
If you like the bose, then go with it, Polk satalite, go with it.
It's an ENTERTAINMENT center, and it is supposed to ENTERTAIN YOU! (Not me, and not the experts, but YOU!)
I personally do not like those tiny speakers, and a hidden sub-woofer, but my turning point was about 8 years ago, when I saw a demo of the bose satalite system (I really do not like bose bty), and in the demo, they were talking about the high "SAR" rating this system had. Now, I have been an audiophile from way back, but was not familiar with the SAR rating, and when I asked, the guy said "SAR - Spouse Approval Rating". I then had a friend who purchased a state of the art speaker system, only to take it back because his wife did not like how big it was, but he was allowed to buy the Bose system.
Now before you buy . . .
Get a reference CD or two or three, and pick ones that you like, and are familiar with. This is a little different from finding the most accurate speakers, where wou would take a recorded source, and compare it to a live source.
Go listen to some reference systems. Go to a high end stereo place on a week day, during the day (so you don't waste someone's time) and say you want to get your ears aquainted to a reference system. Now, look at sytems in your price range, starting at the store you just listened to the reference system.
When you find what you like, ask them if you can return it, no questions asked, within a couple of days, as systems can sound different in your home vs in the store.
Now, Bose is very popular, but I do not prefer them.
I like Polk and B&W speakers, if you can afford them. Polk used to be AWESOME in the lower range speakers, but then they became "mainstream", and started selling expensive systems, and, in my opinion, their lower priced systems lost their sizzle.
After you made your decision, before purchasing, do some research. Is it a "house" brand, or an unknown brand, or is it a name brand. Is their favorable reviews?
I could write forever on this, but I am at work and have to go!
Good luck and remember to have fun.
