Both of those speakers are upgrades from Bose. keep in mind that there are no Bose models made for home use that have proper tweeters. Pretty much you have a 2.5" paper midrange per "cubelet" in those satellites to create most of your sound...then one or two 5-1/4" speakers in the "subwoofer" for bass. The Bose layout is good foe aesthetics, but not sound quality.
Ignore wattage unless you really plan on cranking them up for extended periods of time...such as "party speakers". I've ran speakers (Sansui SP-35) rated for 35w MAXIMUM (10w continuous) on amps as big as 1000wpc (Crown K series). Think of it like owning a Ferrari....you can easily go fast enough to cause real trouble, it's just a matter of having enough self-control to keep that lead foot in the upright position
Look at ratings like frequency response, impedance, sensitivity, weight if you plan on wall or cieling mounting them.
