I have a 5 speaker surround sound setup on a 55 inch samsung. They are boston acoustic digital theater 6000. I wanted to get my father 2 floor tower speakers to add to them. THe subwoofer now acts as a receiver for the current five. Will I need to get a receiver to hook them all up? I think on the back of the woofer is 1 red and 1 white component slots available but it says vcr under it. Any thoughts would be great. Looking to get these setup before xmas. I also have a panasonic blu ray if that can be used at all in the setup? Im assuming if I buy these two speakers they are not going to have components though? So curious on how they will all tie in together.
