I'm in the market for some 2.1 subwoofer PC speakers. I don't really know much about audio, but i would like some recommendations for systems under 100 dollars. My two choices for now are the Logitech Z4's and the Logitech X-230's. I'm on a tight budget, and just like any other consumer, i would like to have a pair of cream of the crop speakers for under 100$. Are there any better speakers than the two? What do you guys recommend in this price range. Thanks in advance.
