1. Check clearance around the mounting area before installation, ensuring the
area is free from obstruction, and there is adequate depth
for the speaker.
2. Check that the area chosen for mounting the speaker is flat. If the area is
curved, it may not
be possible to fit the speaker without "twisting" the frame.
3. If the installation area is only slightly curved, use the extra thick closed cell
foam gasket provided.
4. Using the supplied mounting template, mark the correct diameter on the
mounting surface.
I

5. Use a suitable cutting tool to remove the marked surface, and drill four holes
for the screws to pass through.
NOTE: Confirm you are happy with badge position relative to mounting holes
6. Connect the wires before mounting the speaker. Be sure to observe the
correct polarity.
7. With the grille removed, mountthe speaker using the four stainless steel
screws.
DO NOT over tighten the screws, especially if the mounting area is
not flat.
8. Twistthe grille into position.
INSTALLATION TIPS
Any speaker will only perform to its best capabilities, when correctly placed in the
listening area.
FUSION Engineers recognise that unlike a home or motorvehicle
installation, there are
an extremelywide range of marine environments where
speakers may
be placed. FUSION Full Range Marine Speakersare optimised to
perform in the widest possible range of mounting locations, buta
little thought
and carewith placement
will always be rewarded with bettersound.
• High frequencies are directional. Placing the speakers low down in the boat
will lose some of this information. (To improve dispersion of the high
frequencies, the
grille on your FUSION Full Range Speaker has a uniquely
designed "phase correction" feature
in the centre, for best performancewith
the
grille on.l
• Speakers should be placed to simulate a "sound stage", by being placed where
you are ableto hear both speakers in a stereo situation.
• Bass is dependant on the area behind the speaker. Too small an area will
restrict bass, too large will compromise bass performance.
• Placing a speakersuch that it isveryclose to an open area (where sound from
the back of the loudspeakerhas avery short path to compete with sound from
the front of the loudspeaker] produces the leastbass.
• If possible, try and make the area behind a speaker an enclosure.
Where the speaker is directlyexposed to the outside environment,
it is best if this
is a sealed enclosure. (Especially
if the loudspeaker is exposed to ''wash down", as
a vent might allowwaterto collect in the enclosure.]
Where the speaker is not so exposed
(an inside cabin for instance), a better
bass performance can
be had ifthe enclosure is a ported or vented type.
To help you achieve the best possible result see the optimum enclosure desi gn
recommendations. These are by volume only, and for the ported option, an
optimumvent size/length is given.

Problem Solution
No sound
Check all connections from the source unit and
amplifier to the speaker terminals are correctly
connected
System lacks in bass
Check the connections from the source unit/amplifier
to the speaker. Ensure the positive wire from the
source is connected to the positive of the speaker.
Ensure the speakers are mounted firmly to the
mounting surface
System lacks in high frequencies
Check polarity
Check the bass / treble control settings
on the source unit
Distorted sound
Check all wiring
Check that it is not the surrounding panels of the
craft rattling. Check connections from the source to
the speaker.

SPEAKER GRILLE OPTIONS
FUSION Marine Speakers lwith the exception of MS-FR402) feature two grille
options, allowing you to customiseyour speakers to match or enhance the
appearance of
your craft. Each pairof MS-FR6021 and MS-FR7021 speakers
include a choice of two colours lice white and midnight black].
NOTE: MS-FR4021 only feature the ice white grille option
ICE WHITE AND MIDNIGHT BLACK GRILLES
The ice white grillesare factory-fitted to the speakers with the midnight black
grille options provided in the box (MS-FR6021 & MS-FR7021 only], and offer a high
level of protection.
FUSION recommends using these grilles in high traffic areas,
or where objectsare liable to be moving around or knocking into the speakers.
RECOMMENDED ACCESSORY
Forunique styling of your FUSION marine speaker installation, FUSION
recommends the addition of the MS-FR6021 GS I MS-FR7021GS chrome finished
speakergrille. The chrome
grille adds an impressive, sports styled impression to
your installation
for stand out appeal.

with MS-FR6021
MS-FR7021GS compatible with MS-FR7021
CARE AND MAINTENANCE
As with all products with a chrome finish exposed to the harsh marine
environment, a
little care will help preserve the finish and prevent corrosion.
FUSION recommends thatyou clean any salt water and/ or salt residue from the
speaker
grille with a damp cloth soaked in fresh water.
