“Crossovers” can be set when the “Subwoofer Mode” setting is “LFE+Main”, or when you have a speaker that is set to “Small”. link
The default crossover frequency is “80 Hz”, which will work best with the widest variety of speakers. We recommend setting to a higher frequency that the crossover frequency when small speakers are used. For example, set to “250 Hz” when the frequency range of the speakers is 250 Hz – 20 kHz.
Sounds below crossover frequency is cut off in the output from the speaker set up in “Small”. The cut off bass frequencies is output from the sub-woofer or front speaker.
