"LPF for LFE" isn't what you want to be changing, I'm afraid. Set that to 120 and never touch it again, as that controls how much of the '.1' Low Frequency Effects soundtrack makes it to your sub, and the LFE soundtrack is designed to go up to 120 Hz and never above.
You need to dig deeper into the menus to find the crossover settings for your actual speakers and set it from there. That's the one that needs to be raised to 80 if it's lower for any given speakers. As a test you could set your speaker crossovers really high just to prove that bass management is functioning correctly.
