the two settings to determine the best results.
5. Subsonic Filter Control
This is used to filter out unwanted amplifier output to the subwoofer. Effectively this will filter out all the frequencies up to the
crossover point set with the control. The range is from 15 Hz to 50 Hz. Frequencies of 80 Hz and below cause the subwoofer
to work hard, some subwoofers can easily be damaged when playing very low frequencies. Using the subsonic filter allows
less distortion, delivers frequencies better suited to the subwoofer prolonging its life.
