LFE is low frequency usually from a AVR sub output. Use this if you use the crossover in your AVR. Line is a full range signal from your line out. Use this if you are not using a crossover, and adjust the crossover setting on your sub to blend the best with your main speakers.
"180 DEG" or "0" as far as phase goes" Set this where the bass and PRAT are best at the listening position.
Hope this helps-
