I dont think theres much difference between the GMX and older 2.1 klipsch sets.
FYI, if i was to do it over again I'd get the speakers you are getting because of the simplicity of a 2.1 setup, and I prefer the better range of the klipsch speakers (seperate tweeter and midrange). The bass isnt as good as logitechs but its more than enough for gaming and mp3s.

Good luck and glad to help.

I just tell it like it is and some can't handle it. If your experience is different, well congratu-fukulation.
