Snarf:

The stereo sub article I did was meant as a good compromise to accommodate exactly this bass mis-management situation on all recordings from CDs to DVDs to multi-channel music without having to set the sub configuration differently for each. The Outlaw ICBM does this too, except that it has a fixed crossover frequency of 80HZ in stereo bass mode.

The LFE track is a movie convention meant for low frequency effects - that's why it was created, and when it was conceived, no thought was given to music reproduction. It has it's roots in the days when the movie "Earthquake" was released - music was never meant to come from it. An interm solution during the release of "Star Wars" in 1977 was to use two of the 5 behind the screen speakers in 70mm theaters as "baby booms" - to act as subwoofers. A stripe on the 70mm film print was devoted to this effects track. I know this from conversations I've had with a film mixing engineer who mixed "The Empire Strikes Back".
