What it does not mention is any LFE signal getting mixed into the mains. My interpretation of that would be that no, the front channels do not get .1 in LFE+Main. If you have a dedicated sub enabled, then the LFE channel is directed just to the sub.\n\nYeah, I disagree. Subs + Mains is also called "Double Bass" on some models, and what it means is that both your main speakers and subwoofers are receiving bass frequencies, bypassing the crossover. "Double Bass". I would NOT recommend using LFE + mains unless you have true full range speakers and a very low LPF for your sub(s).\n\nI will repeat, LFE + Mains or Double Bass sends LFE content to both your sub and mains and what you get is double bass, with main speakers and subs stepping on each other.
