Crossovers + LFE
Usually these settings may be left set to the factory defaults. However, your processor allo ws ‘fine tuning’ of the
system parameters most useful in setting up a high-end audio system .
Set the high and low pass filters’ crossover frequency - This sets the frequency at which b ass tones are
removed from the small main speakers and sent to the subwoofer. If you use ver y small main s peaker s you may
wish to raise the crossover above 80 Hz. You may get better res ults with f airly lar ge speakers b y setting the m to
small and using a low crossover frequency so only the lowest tones are sent to the subwoofer . THX certified
speakers are specifically designed for use with an 80 Hz crossover setti ng.

Set the high pass filters slope - A crossover doesn’t simply send all content above 81 Hz to the main speak ers
and all content below 79 Hz to the sub. Instead there is a gradual transition. The crossover poin t is the frequenc y
at which the amount of information in the sub and main speaker is equal. The cros sover slope determines how
gradual or abrupt this transition occurs. More gradual slopes generall y result in a smoother transition from main to
sub. However, gradual transitions can cause distortion in sm all main speak ers becaus e too muc h bass is sent to
them. Gradual transitions with higher crossover settings can als o cause the perceived location of a sound to move
from the correct main speaker to the sub’s location. THX speakers are specifically designed t o use a 24 dB slope
for the subwoofer and a 12 dB slope for the main speakers.
