Q. re 'Stacked Advents' and new AV receiver... I haven't yet set up this system, but here's the equipment: 4 Large Advents (walnut, c.1973) stacked, as fronts 1 Advent 5002 - center 2 Smaller Advents - rear surround Powered 12" sub Onkyo TX-NR809 7.2 receiver (but used as 5.1) Just wondering if I need to manually wire the fronts in parallel to get the stacked effect, or if the Onkyo can do that for me if I just plug them all in... and can the bi-amp feature offered bt the 809 receiver help? I suppose this may be more a question about the receiver than the speakers. The receiver IS rated for 4, 6 or 8 ohm speakers. Many thanks for any expertise you can offer!
