Great review. I happen to have two of these bars, my only concern about them was that you had to put subwoofer behind, in order for the satellite speakers to be connected since the cable length is very limited. How did you manage to accomplish your setup? How did you hide the RCA extensions?

I just got this soundbar and am in the process of installing it. I want to use a different set of surround speakers (Leviton AESS5) connected to the subwoofer. I would think that this is straightforward but the VIZIO support response says that only the supplied speakers will work (no details why though). Has anyone tried connecting different speakers to the subwoofer? What is the subwoofers output impedance? Any chance of frying the subwoofer or speakers?
