Are the two different AVR pre-outputs there just to accommodate different sub inputs? I was thinking an LFE Low Frequency Effects was something specific to 5.1 setups, and would not transfer musical information the same way. (ie, explosions are not music)
They are an internal Y adapter, nothing more. You could use one of the outputs with an external Y adapter and you would have the exact same thing.
Only receivers that have SubEQ2 along with Audyssey allow different signals to be output by either sub output. And then, the only differences are the levels and distances.
If you want to have more than one EQ curve, i.e, one for movies and one for music, you would need an external EQ able to store multiple filter sets.
The "LFE" is a channel in the content. It is routed to the subwoofer output(s) whenever the there is a .1 channel in the content and the subwoofer is set to Yes or On in the receiver. Again, there is no difference between Sub1 and Sub2.
If you are listening to music in 2-channel, (with no .1 content), you can still get a subwoofer output by setting crossovers on the L/R channels. The crossovers will re-direct all bass below the crossover setting to the sub(s).
