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 does n’t simply send all content above 81 Hz to the m ain speakers
and all content below 79 Hz to the sub. Instead there is a gradual trans ition. The cross over point is the fr equency
at which the amount of information in the sub and main speaker is equal. The crossover slope determines how
gradual or abrupt this transition occur s. More gr adual slopes generally result in a s m oother trans ition from m ain to
sub. However, gradual transitions can cause distortion in sm all main speakers because too m uch bass is sent to
them. G r adual trans itions with higher cros s over s ettings c an also c aus e the perc eived loc ation of a s ound to move
from the corr ect m ain speaker to the s ub’s location. T HX s peakers are specif ically designed to use a 24 dB slope
for the subwoofer and a 12 dB slope for the main speakers.
