The LPF of LFE is not "a filter for 5.1 content." It is a Low Pass Filter, (it allows the lows to pass through it, and it filters out the highs.) It affects *only* the .1 channel, which is the LFE channel. It has no affect on the bass that is re-directed from the mains to the subwoofer output.
The .1 LFE channel should not have anything in it above about 80 Hz, so setting the filter at 80 Hz is mostly not an issue. However, some recording engineers do place some content in the LFE channel above 80 Hz, and if you have the LPF of LFE set to 80 Hz, you will lose that content. If you are afraid you might be losing some content, set it to 120 Hz.
Or, try it both ways. It doesn't cost anything, and you can always reset it to the setting you prefer.
