Sheep , BTW, I left you a PM.
Ok, I am understanding all of this. I do have my main speakers set to small.The crossover is set to 80 Hz. I have 2 settings for my sub. LFE & Normal. The problem is that according to my manual, when I am using an LFE signal, the switch must be set to LFE, not normal in order to use the crossover adjustable switch.
Straight from my manual: If you are using smaller bookshelf speakers that do not extend to the lower frequencies, set the low pass crossover to a higher setting, betwen 120 Hz, and 150 Hz.This control is not used when the LFE switch is in the "LFE" position.So turning the knob all the way up won't do anything.
