About phase switching
·Some sound output from the subwoofer may not be output from the front/rear speakers.
It contains the same frequency range as the sound you hear. Depending on in-vehicle conditions, the
phases of these sounds may be reversed (interference), causing the frequency bands to cancel each
other out. What prevents this phenomenon is the phase switching of the subwoofer. Depending on the
conditions inside the vehicle, select whether the phase should be positive (output at the same time as
the front/rear speakers) or reversed (output at the same time as the front/rear speakers). .
About the cutoff frequency
· The subwoofer outputs frequencies below the frequency selected from 50, 80, or 125 (Hz).
