I'm getting the subwoofer for my home theater setup, but I'm really confused when it comes to the inputs. I believe there are three different inputs on the back of most subwoofers, red & white rca looking ones, the spring(?) connectors that are look like regular speaker ones, and finally the LFE.
My knowledge is very limited in such regard however, as far as I understand it, the single-cable input so called "LFE" is for the 5.1 home theater setup whereas it represents the 0.1 from 5.1. Also, I heard something about LFE is to bypass the crossover(?) section of the subwoofer, and this is where I get really lost.
What does the LFE stand for, and what does this input do? Can this be considered as the digital input of the subwoofer (not compressed) like the opticals and coaxials???
