I have Onkyo TX-NR616 I originally have DefTech procinema 60 5.1 (4 satellite, 1 center and 1 sub). This setup was good. Then I upgraded to towers. Replaced 2 of these satellites with 2 DefTech BP 8040ST towers. The 150 watt sub that came with procinema 60 5.1 is of no use, because the towers are giving good enough bass. Now, I am trying to put these 2 satellites and spare subwoofer to best use. Can I add these 2 satellite speakers and the sub woofer to center channel? If so please suggest how to make the connections.
