RUN IN PROCEDURE
FLI recommends that you follow the run in procedure for the subwoofer detailed below.
When your subwoofer is used for the rst time, like most brand new items it is naturally very stiff and
rigid. It will take time for the moving parts of this Subwoofer to loosen up before the subwoofer will be
ready to deliver its full potential.
For the rst thirty hours it is recommended that you play the subwoofer initially at low to medium
volumes, gradually increasing the volume level as time progresses.
As a guide, if you listen to your subwoofer for one hour every day it will take a month for the subwoofer
to run in properly.
You will notice a big change in the sound of the Subwoofer over this period. As the spider and surround
begin to run in the sound will get deeper and harder, also the output of the subwoofer will increase as
the suspension loosens up.
The subwoofer is like your car’s engine, it needs a few thousand miles before you can drive it to its full
potential. Driving it into the redline from the rst day will mean engine damage is certain and will not be
covered by warranty.
Failure to follow this simple procedure is the most common reason for a Subwoofer to fail after a very
short period of time.
WIRING
Please follow the wiring diagram below and ensure that correct polarity is observed as incorrect
wiring may cause the subwoofer to be out of phase with the rest of the system and result in a loss of
bass.
