SUBWOOFER HIGH PASS ORDER
Here you may set the low-end slope. If you have a subwoofer that has strong output
below 20 Hz, or if it uses its own low-frequency input protection (check with its
manufacturer, don’t assume) then selecting Flat may improve system performance.
If on the other hand you have a subwoofer that is designed to be flat to a certain
frequency then have response that drops very quickly below that, manually selecting a
steeper than average slope may be beneficial. Normally, ARC does not auto-select a
slope that is steeper than fourth-order (24 dB per octave rolloff) although up to eighth-
order (48 dB per octave) is available through this manual selection.
SUBWOOFER HIGH PASS FREQUENCY
Use this with High Pass Order when manually creating a curve on the lower end of
the subwoofer’s response. The left side of the red measured curve is the guideline for
shaping the target curve. An attempt to use this as a bottom-end boost to increase
low-frequency output is likely to be detrimental to the subwoofer’s performance. If the
subwoofer’s specifications indicate that low-frequency output should be greater than the
uncorrected in-room response curve is showing, then the proper solution would be to
reposition the subwoofer.
