Setup
• Subwoofer • User’s G Guide
Crossover frequency can be modified for optimal integration with the other
speakers in your system.
Adjustable high-cut filter plus high and low level inputs.
Do not place the subwoofer with its metal plate against the floor.
Do not place the subwoofer where it might be knocked over or exposed to
falling objects.
Placing the subwoofer on the same stand or shelf as your turntable can result
in a low frequency rumble or acoustic feedback.
To prevent the cabinet from warping or discoloring, do not place the subwoofer
in a place where it is exposed to direct sunlight or excessive humidity.
Place the subwoofer at least 2-3 feet away from your television or computer
disk drive system. The subwoofer’s magnet could distort the colors of your TV
picture or erase your disks.
Test the subwoofer in different locations to determine where the best balance
is between your satellite speakers (if used) and subwoofer.
Although low frequencies are nondirectional, factors such as room reflection,
standing waves, resonance and absorption strongly affect your subwoofer’s
performance. For maximum bass output, place your subwoofer in a corner. To
reduce output, move it away from corners and back walls. Even slightly moving
the subwoofer can have a major effect on bass response.
The position of your subwoofer greatly affects its bass response. Adjust the
subwoofer’s volume control in relation to the left and right speakers, and adjust
the subwoofer’s high-cut filter to obtain optimum overall sound.
Choosing a Location
The metal control panel on the back of the subwoofer acts as the heat sink
for the subwoofer’s internal amplifier. Therefore, place the subwoofer at least
4 inches (10 cm) away from a wall, and do not let anything come into contact
with this panel.
