I just recently upgraded my Infinity BU1 subwoofer and cheap fronts with a KSW12 Klipsch sub and Klipsch KSF8.5 fronts. I currently have all of the speaker settings on my receiver set for "small" and my LFE xover output set at 100(my only options are 100,150, and 200). I also have the xover set at 100 on my sub to match my receiver. I need to know the correct settings for optimal performance, based on this equipment. I also have a phase switch on my sub, which gives me options of 0 and 180. Which one should I choose?
