Samsung HW-H450
I am adding this sound bar to a 60" plasma HDTV. It will be placed under the TV in an approximate 17' X 15' condo front room. I am curious if it is possible to add another sound bar? Or, if I was to add additional speakers, will I need to add a receiver? Also when I connect the initial sound bar, will the TV audio still be playing for additional sound or they just automatically shut off?
