Klipsch ProMedia 5.1 AND Klipsch ProMedia 4.1 connected to my system effectively creating a quasi 6.1 surround sound solution (but not really at all). So, I basically have a 5.1 set up with double the amount of front left and front right speakers and double the surround speakers. (If I kept my GTXP, I would've been able to say that I had a 6.1 set up--oh well.)
