I should know the answer to this but for some reason I am unsure of myself tonight. When you are running DD-DTS, does the subwoofer get both a discrete signal (.1) and whatever is below the crossover point for the other five speakers? Or does it only get the summed bass from the five main channels and there is no discrete signal? For some reason I kept thinking that a sub would only reproduce bass from the 40Hz crossover point (Studio-100's) and below. I completely forgot that there was a separate signal going to the sub irrelevant of where the crossover is set (assuming all speakers set to small) please help me with this brain-fart.
