    The crossover between the subwoofer and the speakers is not the same as the LFE setting.  The crossover determines what frequencies will be sent to the speakers and what will be sent to the subwoofer.  It should be set where MultEQ found it.  The LFE setting is a filter that applies only to the separate LFE track in 5.1 content.  It is found under "Surround Parameters" in your Denon and should always be set to 120 Hz.  It's not related to any acoustic measurement.  The content in that track is authored up to 120 Hz.

    The THX recommendation of 80 Hz applies only if you have THX speakers.  They are designed to integrate with a THX subwoofer.  However, room placement can influence the low frequency behavior of speakers and so the measured roll off can be lower or higher.

    Hi Chris, 

    at 40hz and 50hz crossover,There seems to be lack of bass in music.It is wise to override the audyssey and set it at maybe 60hz or 80hz? Besides,audyssey also set my subwoofer at -3db.

    It's fine to move the crossover to a higher value.  Your subwoofer was set to -3 dB to match the other speakers in level.  It's just a relative adjustment to make up for whatever setting the subwoofer volume control is set to.
