Important recommendations
Before attempting any installation work, it is very important to verify how much space is
available to fit the speakers into the vehicle.
• For direct replacement of original speakers, please check there is enough space for your
new Focal speakers and grilles.
• Ensure the speaker is clean from debris and metallic particles that maybe attached (especially
after drilling)
• Use the foam gasket supplied (inside the grille), for airtight placement of the speaker into
the panel.
Choice of installation and positioning of speakers
To achieve best results for your installation, please follow these simple guidelines
• Speakers positioned in the most forward location possible, for correct staging.
• When installing Polyglass coaxial speakers into the rear of the vehicle (rear parcel shelf or
left and right quarters), the left and right speakers should always be positioned far apart
from each other, and the most forward possible, to the listener.
If installed into the rear parcel shelf, the speakers must be fixed rigidly in place. If holes are to
be cut into the parcel shelf, ensure it is still strong enough to accept the speakers. The panel
must remain strong, rigid, and free from any vibrations. If the parcel shelf is allowed to flex, a
possible acoustic short circuit, may occur drastically decreasing the speakers performance.
Orientation of the tweeter
The tweeter includes a rotational and adjustable tilt
mechanism, that gives the user a huge advantage in
deciding the position the tweeter points, ultimately changing
the strength of the high frequencies produced.
Simply by carefully turning and twisting the tweeter into
position ensures it is on axis to the listeners ears.
Thus:
• obtains correct integration of the system,
• optimise the sound stage image.
