Of course, make sure you listen to any speakers before you buy them. I'm not a real fan of the Logitech speakers, but other people, like Willz or one of my brothers, love them. There's not a real one-size-fits-all method to speaker selection.
I have never seen anywere that actually has these speakers out on show for you to listin to before, i remember going into pc world and the subwoofer was half hanging off a shelve under a computer, but it was on quiet and i dont think they would let you listin to it.
