I own the radio and and the system. If you're only going to use it in a small space the radio will do. If you want about triple the 'clean' power, to take outdoors or whatever, go with the system.

Hell, if you have the spare cash by 'em both. Bose offers an unconditional, no cost to you (not even shipping), right to return within 30 days if you are not completely satisfied. So pick the one you like and send the other one back. You have nothing to lose.

I love both of mine. As a bonus, their customer service is beyond awesome. A class company if you ask me.
