I am a newbie at this and I think I have already outsmarted myself. I have a Polk Soundbar 50 I am planning to use in my new surroundsound setup. I also have a pair of speakers built in the ceiling behind me. My receiver is an Onkyo TX-SR606 and I have a subwoofer. My question is - is it better to set the soundbar up and connect the rear speakers for a 7.1 setup, or should I use the Soundbar as front and center speakers and use the ceiling speakers as surround sound for a 5.1 setup? If 5.1, then how do I wire the Soundbar for that? Also, should I upgrade the speaker wires for the Soundbar? Thanks for any help.
