The HP Filter control rolls off the low frequencies below the
specified frequency (60, 80, or 100 Hz) at a slope of -24 dB/
octave. Engage this control if you are using a subwoofer in
conjunction with the Sceptre S6/S8 monitors, and set it to
the same frequency as the crossover to the subwoofer. If
you’re not using a subwoofer, set the control to Linear.
3.5 Acoustic Space Setting Suggestions
When a monitor is placed close to a wall, or in a corner,
the low frequencies tend to be emphasized more than
if the monitor is far from any room boundary; this effect
is called “boundary bass boost.” It is most pronounced
if the monitor is in a corner and less pronounced,
but still present, if the monitor is near one wall.
To compensate for this bass boost, the Sceptre S6/S8 provides
an Acoustic Space switch that cuts all frequencies below
250 Hz by a fixed amount.
If the monitors are close to the
corners of the room, start by
setting the Acoustic Space switch
to -6 dB, which provides the most
bass attenuation.
If the monitors are close to the
back wall, try setting the Acoustic
Space switch to -3 dB or -1.5 dB for
less attenuation.
If the monitors are far from any
wall, there will be no bass boost, so
set the switch to 0 dB.
These are merely starting suggestions; use
your ears, experiment, and go with what works
best for your listening environment.
