SB-2000 Pro
SUBWOOFER
ADVANCED SUBWOOFER CONTROLS
Volume
Adjust to make your system’s low end more powerful and extended while remaining accurate.
The subwoofer should sound like it’s naturally adding bass for all the speakers without overly
drawing attention to itself. Different content has different levels of output so it’s normal to adjust
volume based on source material and your personal listening preferences.
Low Pass Filter
Enables smooth sonic transition and flat frequency response between speakers and the
subwoofer. This allows you to control the upper frequency cut-off to blend with main speakers.
It also allows you to adjust slope, or the rate at which the low pass filter rolls off. If using an AV
Receiver with a Subwoofer Output, leave in the OFF position.
Phase Adjustment
Solves sound wave cancellation issues at specific frequencies and perfectly aligns the arrival of
output from speakers and subwoofers to your listening position. Normally set to 0° if the
subwoofer is near the main speakers. Adjusting Phase shifts timing of the subwoofer output to
align with the main speakers or additional subwoofers.
Polarity (SVS App Only)
In some cases, reversing polarity solves dips or humps at the crossover frequency between a
subwoofer and speaker and can be used to fix bass nulls or overly boomy spots in the listening
area. Reversing the electrical polarity of the subwoofer amplifier makes it so the woofer moves
in when speaker drivers move out and is normally set to positive.
Parametric EQ (SVS App Only)
Powerful tool for removing peaks and dips in your listening area, and for creating custom
subwoofer output based on personal listening preferences. Works best when used with acoustic
measurements.
Allows you to set the desired center frequency of the filter, increase or decrease the SPL dB of the
filter, or adjust the bandwidth of the filter.
Room Gain Compensation (SVS App Only)
Fixes bloated sounding bass by optimizing low frequency output and extension when too much
sound wave density is being created by a small room.
Presets (SVS App Only)
Allows up to three pre-saved settings for movie, music and custom. This enables easy switching
to optimize your SB-2000 Pro’s output and settings based on your specific listening preferences
with different kinds of content. If using the SVS App, these presets can be renamed as desired.
