What is LFE on sub connections


A no-brainer to most on this forum, but I'd like to know what this connection does in any system, music or HT? My HT connection was set up from the receiver's sub out to the L/R line levelon the sub. That is what I was advised to do. But what is the LFE, and have I made the best connection for my HT system?
For music, what connection is best?

Dogmatix,

Does your question imply that your receiver has both sub and LFE outputs?

I must admit that I hadn't made such a distinction, often referring to my sub output as LFE. But I see that the manuals for my Proceed PAV/PDSD pre/pro label the outputs only as sub, with no mention of LFE. The balanced sub output from my PDSD goes to a Velodyne SMS-1 bass manager (room correction) then via balanced line to a Velodyne HGS-15. That configuration, crossed at 80 Hz, provides the felt more than heard sound of a big pipe being invoked as well as the high level low frequencies in films. So, is there a practical distinction except as a separate track in the film industry?
