The low-pass control will raise or lower the frequency cutoff point of
the woofer (not the crossover frequency between the bass and
midrange). Turning the low pass filter up to a higher number will
extend the upper bass regions into the midrange without affecting
the low bass level. Some rooms may require that you set the low-
pass filter to 115Hz or more. Do not be afraid to increase this
control to give the sound more body.
In general, you will find that the BASS GAIN and the LOW PASS are
adjusted in opposite directions. When you turn the gain up, the low
pass should go down, and vice versa (but with different amounts).
Next, set the woofers using more than just a voice. Select some
music that you know to have good deep bass. Adjust the gain of
the woofers for a natural and powerful bass sound. Use a
symphonic piece of music if you can, or use a natural bass
instrument like a stand-up bass for your guide. Try to make it sound
real. You may have to return to the vocal to make sure you have
not gone too far in one direction.
If, at this point, it does not have enough mid bass, turn the low pass
up to a higher position or, alternately, position the speakers closer
together in order to achieve better lower midrange coupling
between the main speakers. If it sounds too “fat” turn the low pass
control down or adjust the gain down. At this point it is suggested to
use the low pass filter control until you get to the refinement stage.
Imaging and Soundstage
While imaging and soundstage are controversial subjects (how do
you ever know that the soundstage is recorded correctly in the first
place??), it is vitally important to our enjoyment of a recorded
musical event. The G2jr is able to deliver a realistic soundstage
only if the recording contains such realism.
If your vocal selection is a well-recorded audiophile CD or LP, the
performer (assuming that he or she is not very close miked) should
appear to come from between and behind the loudspeakers and be
at the appropriate height and size for a standing person. If it is not,
there are several remedies that will address this.
Assuming that the vocal recording is accurate, if the vocalist
appears to be larger than life, you should first check the system
volume. Is it a volume that would be appropriate for someone
