First, it helps if you double check the speakers/subwoofer levels with an SPL meter and an external disc after you have run the auto calibration program. You should not use the internal test tones inside the receiver as they bypass any correction or equalization that Audyssey has performed.

Second, a Low Pass Filter (LPF) of LFE of 120Hz is correct. The LFE (.1) channel has absolutely nothing to do with the redirected bass from the small speakers that go to the subwoofer. The information in the LFE channel is put there by the audio engineers at the studio and extends up to 120Hz. If you lower this to 80Hz, you will lose the information from 80Hz to 120Hz that the engineers may have put there. At the same time, it is possible that some older DVD's may have full range information in the LFE channel due to incompetence or carelessness. You set the low pass to 120Hz to block any information above 120Hz in order to protect the subwoofer from distortion and/or damage.

You can find a lot more information in the following threads:
