2.1  Begin with the bass level 
For now, leave the low-pass filter set at 100 Hz, This control will be 
addressed later. Turn the volume control of the woofer amplifier up or 
down until the voice sounds correct. Whatever controls you use, turn 
them up and down only a little at a time. It is easy to turn it up or down 
too much. 
Concentrate on the mid-bass regions (as opposed to the very low 
bass in your recording) to achieve a natural blend. The voice and the 
music accompaniment should sound as if it were cut from one cloth, 
not separate. The reason we use a female vocal to start is that male 
vocals will have very much more bass content, and the lower bass 
may obscure the mid-bass crossover point. 
If the voice sounds “thin” or does not have enough “chest” to its 
sound, turn the woofers amplifier’s volume up till it does. If you find 
that turning the volume up creates too much low bass, you may want 
to experiment with lowering the low-pass filter cut-of frequency.  
The Low-pass Filter control will raise or lower the frequency cut-off 
point of the woofer. Turning the low-pass filter up to a higher number 
will extend the upper bass regions without affecting the low bass level.  
Some very large rooms may require that you set the low-pass filter to 
115Hz. Do not be afraid to increase this control to give the sound 
more body, or reduce it if you find that there is mid-bass boominess. 
Next, set the woofers using more than just a voice. Select some music 
that you know to have good deep bass. Using the volume control on 
the servo amplifier’s remote control, set the woofers for a natural and 
powerful bass sound. Use a symphonic piece of music if you can, or 
use a natural double bass instrument for your guide. If there is a 
running bass line, each note should sound equally loud. 
Try to make it sound real. You may have to return to the vocal to 
make sure you have not gone too far. 
If, at this point, there is not enough mid-bass, turn the Low-pass 
number to a higher position or, alternately, position the main speakers 
closer together in order to achieve better mid-bass coupling between 
the main speakers. If it sounds too “fat”, turn the Low-pass control 
down or adjust the volume.
