We just bought a house which comes with a whole home stereo system. There are 12 speakers in total placed in stereo pairs throughout the house. Two of these speakers are close to, if not dead center in the living room which is also where the connections for these speakers live. The house was built in 2010 so the speakers are old, but they do work. The receiver I am using is the Onkyo TX-NR676. If I could use the two living room speakers in a surround sound setup, how would you do it? Do you think the speakers would hold up?
