Adjusting the Subwoofer Filter
You can use the subwoofer filter setting to control the subwoofer cutoff frequency for each zone, which can enhance the blend of the sound produced by the speakers and the subwoofer. Audio signals above the selected cutoff frequency are not passed to the subwoofer.
NOTE:
If a DSP setting has been applied to the zone, this setting cannot be changed on the stereo. You can view the DSP setting for the optimal cutoff frequency as calculated by the DSP controller, but you cannot adjust it.
