Remove both the subwoofer and the bass port tube
from their packaging. Using the hex wrench provided,
securely attach the port tube to the subwoofer. When
properly oriented, the port tube should be “Up” when
the subwoofer is resting on its base.
Make sure that each of the hex screws is securely
tightened to prevent the possibility of any vibration
or rattling from the subwoofer when installed. Once
assembled, the subwoofer is ready for installation.
