I have used the Klipsch ProMedia v2-400 (with the older preamp) system since 2001. It still sounds fantastic, great clarity and excellent bass. I have a Mac laptop and need to use a Y-connector for the stereo, so I decided not to connect the rear speakers recently. I was wondering how the new 2.1 system compares to this setup? The v2-400 has a dual 8" sub while the 2.1 has a single 6.5". Does anyone have any experience with both of these models?
