Do you guys set the cinema eq to on or off? Also I have Mains that go down to 40 hertz, alot of people say if your mains can go down to 40 set them to large and +LFE. Others say just set them to small and let the sub do it!?!? Well aren't I wasting some of the speakers potential by cutting out at 80 hertz? Also the speakers will be fine as long as they are receiving clean power, even though they can't produce below 40... correct?! What's everybody's thoughts?
