Howdy, I've currently got a 5.1 system and with the redesign of my HT room, I can now have a rear speaker. The question is, Is it really worth it? Considering most DVD's are only 5.1, What would a rear center provide? better surround sound? My receiver is 7.1, So for 6.1 mode will it take parts of the sound it would normally put on the rear speakers and put it through the rear center speaker? What do you have? 5.1 or 6.1 or 7.1?
