been playin around with my system for weeks now. There are that many variables it is frighteneing! Amp is a 3802 and the sub a Yammy YST-60W (yes I know !). Speakers are a little varied but I have a full complement of 7 with the amp defaulting to 6.1 with the rears matrixed. My question is with regard to the sub settings on the amp which can be adjusted, think it is 60/80/100/120 (K)hz. I presume that this is the frequency beneath which everthing is sent to the LFE. On the sub is further adjustment, think it is from 50 to 200 (K)hz. Should these be set at the same level? And if so, roughly where?
