I was using them, but I don't need sound like this, my SBC560's work great for me. They are in excellent shape and work great. They can be either 2.1 or 4.1 with simulated surround. When you first hook them up, you have to jiggle the speaker connector to find the best contact, but after that they are fine. These suckers sound awesome, better than the Bose stereo in my cadillac. $30 plus shipping. Pics to come later.
