Volume Control
Subwoofer Control Panel
The volume control runs from 0-10. We suggest the volume be set to 5 and then controlled by the
subwoofer setting on your receiver. When listening to movies or music make sure that the subwoofer
does not go into distortion. You can hear this as a distorted crackling sound which is usually caused
when the subwoofer level on your receiver is set too high. Ease the volume back so you get a good
solid bass. This will ensure the subwoofer will play for years to come.
Crossover
The crossover is the heart of the ES40 system. As you turn the crossover control up you add upper
bass. The best setup is to fill the gap between the speakers that can not produce lower bass. At normal
levels the speakers go down to 120Hz. The control starts at 40Hz and goes to 200Hz. We suggest
around 120 Hz to start. You can add or decrease the frequency to achieve the correct balance for either
music or movies. The control only adds higher frequency. It does not alter the low frequency.
Base Extension
This control adds extra depth to the frequency you have the crossover control set to. We call this bass
extension. The control starts at 0dB which is normal. If you find you are not getting the extra bass and
feeling from the subwoofer you can increase the Bass Extension to get the desired effect.
Phase Control
This function adjusts the phase of the subwoofer driver. This adjustment is required to ensure that the
subwoofer and all other associated loudspeakers operate "in sync." If your main speakers are at the
front of the room the woofers are pushing forward. If your subwoofer is at the front of the room the
woofer will be pushing forward. Turn the phase control to 0. At the back of the room the subwoofer is
pushing in an opposite direction. Turn the phase control to 180 degrees and the subwoofer will fire in
the opposite direction and be in sync. If you place the subwoofer at the side of the room you run
between 40~160 degrees. To hear bass all around the room you will have to adjust the phase to find the
best setting.
