Input:
the Klipsch Promedia 2.1 really opened up the sound on my new dell desktop computer. It puts out an amazing amount of sound, and really deep bass from the sub-woofer. The satellite speakers give me a nice, open sound field that rivals my bose system in the living room. Of course, there was an initial problem that turned out to NOT be the fault of the speakers. I initially set up the system using WINDOWS media player. MISTAKE! Totally distorted high end! I switched to REAL PLAYER, and the distortion problem was instantly solved.
