Crossovers + LFE
Usually these settings may be left set to the factory defaults. However, your receiver allows ‘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 bass tones are
removed from the small main speakers and sent to the subwoofer. If you use very small main speakers you may
wish to raise the crossover above 80 Hz. You may get better results with fairly large speakers by setting them 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 setting.

Set the high pass filters slope - A crossover doesn’t simply send all content above 81 Hz to the main speakers
and all content below 79 Hz to the sub. Instead there is a gradual transition. The crossover point is the frequency
at which the amount of information in the sub and main speaker is equal. The crossover slope determines how
gradual or abrupt this transition occurs. More gradual slopes generally result in a smoother transition from main to
sub. However, gradual transitions can cause distortion in small main speakers because too much bass is sent to
them. Gradual transitions with higher crossover settings can also cause the perceived location of a sound to move
from the correct main speaker to the sub’s location. THX speakers are specifically designed to use a 24 dB slope
for the subwoofer and a 12 dB slope for the main speakers.
