why not set everything at 80hz and everything above 80hz = all the speakers and everything below = the sub?

doesnt make sense to have 40hz worth of frequency overlapping (80hz - 120hz).

Actually, it makes total sense. There's no "more amplification" here. Everything 80hz and below gets sent from the speakers to the sub. Thus, everything is played at 80hz and below. However, you're forgetting the .1 in 5.1/7.1 tracks. Audio specifically for LFE is anywhere from 120hz and below.

If you find that voices or too much bass gets dropped to the sub, a good middle point is usually 100hz. I have my LPF of LFE set at 120hz though and have never had an issue.
