Run in procedure

FLI recommends that you follow the run in procedure for the subwoofer detailed below.
When

your Subwoofer is used for the first 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 first 30 hours it is recommended that you play the subwoofer initially at low to medium volumes, gradually increasing t he

volume

level as time progresses.

As a guide, if you listen to your subwoofer for 1 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 sou nd
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 first 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.

Installation

The FLI Frequency subwoofer can be installed in a variety of different ways, the most suitable will depend upon your application.

Free-air installation

The FLI Frequency Subwoofer can be mounted free-air, but this does not mean that the woofer can work without any form of
enclosure.

What it does mean is that the enclosure can be very large and therefore the subwoofer can utilise the vehicles boot as an
enclosure.
The

Subwoofer needs to be mounted to a rigid panel as excess vibration will result in poor sound quality. The panel or baffle, should
also seal the output from the front of the Subwoofer from the output from the rear otherwise poor sound quality, known as phase
error, will occur. This simply means that the output from the rear of the woofer will cancel out the output from the front resu lting in a
loss

of bass.

As

the enclosure in free-air applications is so large it is worth noting that the power handling of the Subwoofer is reduced to half that

of

the same woofer in a measured enclosure. Please take this into account when choosing your amplifier.

The

sound quality of a free-air mounted Subwoofer will not match that of the same subwoofer mounted in a measured enclosure.
However in applications where building a traditional enclosure is impossible, free-air mounting will add increased bass response to
your

system.
