I would think that even if you set independant x-overs to your fronts, center, and surrounds, that it filters out everything BELOW those x-over points from entering into those particular speakers because everything up to 120 is in the LFE anyway. That is why we are "usually" encouraged to bypass the x-over on the sub so as not to accidentally eliminate any frequncies up to 120. So again my question is if we set all our speakers to small as most people suggest, and we set the x-over to 80, then everything below 80 gets filtered out from the speakers that are set to small and sent to the sub as it should. But what is the cut off from the processor when all speakers are set to small...is it also 80??? If it is higher than 80 then we all will have a hole in our sound!
