Jason(and Jay) the point about using a 120Hz LFE setting isn't strange, since as Dave(dewd)has pointed out it refers only to the upper limit of the sub for LFE material and doesn't affect the crossover frequency(say 80Hz)for handling bass redirected from speakers set "small". The LFE channel theoretically extends to 120Hz, but in practice very little if any content is inserted above about 80Hz. The reason for not setting the LFE filter control to the full 120Hz is that there may be some extraneous noise(very little)up there; others want to set it at 120Hz to be certain of getting all the LFE content. Either way, it doesn't appear to be very significant to me, although the author of those suggestions apparently feels otherwise.
