Owner's Manual

&crossover : This section is for selecting the cut- off frequencies for the low-pass filter (LPF) and
subsonic filter (a .k.a. infrasonic or high- pass) .
0Subsonic: Provides adjustment of the lower F cut- off point below which all frequencies are
filtered out at -24dB/oct. Very low freqencies can waste amplifier power and damage subwoofers.
This adjustment is especially important for ported enclosures to prevent over-excursion below the
tuning frequency.
0LPF : Provides adjustment of the upper F cut- off point above which all freqencies are filtered out
at -24dB/oct. Unwanted high frequencies allowed to play through subwoofers can cause boomy,
buzzy bass that is easy to localize. With a steep -24dB per octave slope, the cut-off frequency can
be set higher, allowing more punch with less distortion and optimized integration with full-range
speakers for impactful up-front bass.
Note : If the subsonic and low - pass filter cut-off points are set too close together, only a narrow
frequency range will pass through and may result in significantly reduced output .
