    The signal sent to the subwoofer line-out of an AVR consists of two components:

    1. The low frequency content in each channel.  Content below the crossover frequency set for each speaker is redirected to the subwoofer.
    2. The content found in the separate LFE track in 5.1 content

    Unfortunately there is a great deal of confusion in the terminology and many refer to the subwoofer signal as "the LFE signal".   If speakers are set to Large or Full Range then there is no crossover frequency defined and so _NO CONTENT WILL BE SENT TO THE SUB _from those speakers!  Read more about Bass Management here.
