4” 2 WAY MARINE

BOX SPEAKERS

INSTALLATION TIPS

Any speaker will perform to its best capabilities, when correctly placed in
the listening area. FUSION Engineers recognise that unlike a home or motor
vehicles installation, there are an extremely wide range of marine environments
where speakers may be placed. FUSION Marine Speakers are optimised to
perform in the widest possible range of mounting locations, but a little thought
and care with placement will always be rewarded with better sound.

• High frequencies are directional. Placing the speakers low down in
the boar will lose some of this information.

• Speakers should be placed to simulate “sound stage”, by being
placed where you are able to hear both speakers in a stereo situation.

TROUBLESHOOTING

Before you contact your FUSION dealer or service centre, FUSION requires that
you do some simple trouble shooting to help diagnose the problem.
