When looking for computer accessories, you'd be foolish not to first check Logitech. The Z523 is your standard 2.1 speaker system. It's 6.5-inch subwoofer pounds the ground with solid bass, while the satellites handled the rest of the duties. Our favorite feature, however, has nothing to do with the sound: We like the controls and inputs found on one of the satellites. You won't need to reach under your desk to connect your computer, or adjust the base and volume-everything is done on the actual speaker. Nice.
