People should feel free to experiment with different crossovers and settings on their speakers, rather than conform to what is believed by the masses. They may well like the "preferred" setup but then again, why not try setting the fronts to full range....isn't this Ian's preferred setup vs Alan's 80hz small recommendation on the fronts(correct me if I'm wrong)? In the end, whatever YOU like is the right setup.

Half of communication is listening. You can't listen with your mouth.
