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.
