Woofers / Midranges Mounting - Focal Utopia Beryllium Serie Manuel De L'utilisateur

Woofers / midranges mounting

Woofer location
Woofers positioned ideally high
in the doors (fig. 1, A), produce
optimal midrange frequencies.
Woofers positioned mid in the
doors are also a solution to
obtain good linearity (fig. 1, B).
If the woofer-mids are positioned
low in the doors (fig. 1, C),the
loss of midrange will be im-portant.
The woofer-mids from the Utopia
Be range can also be placed low in
the "kick-panels" (fig. 2, D) of the
vehicle. This is to further optimize the
stereophonic imaging and staging.
This mounting only suits to Utopia
Be 5". Crossblock will allow to
obtain a fine setting according to
the location.
Midranges location
3" midrange (n°7 Utopia Be kit) is
made to be install near tweeter, on
dashboard (fig. 2, E), in order to
have the better staging. 0.5l volume
aims at going down to 180Hz.
Mounting advises
Utopia Be woofers and woofer-
midranges have been designed for
a multitude of vehicles installations.
It is worth understanding the basic
requirements for installing such
products. These woofers and woofer-
midranges are abble to deliver
enormous amounts of energy, during
their positive / negative movement.
Therefore it is imperative that they
be fixed rigid to the desired location
(fig. 3, A). Resin might be used
(fig. 3, B). The fixing location should
also be strengthened when necessary.
Panels should be strengthened to
eliminate any unwanted vibrations
and screwed on a metallic part
of the vehicle (fig. 3, C). Such vi-
brations will drastically reduce the
overall performance. These drive
units should be fixed and sealed
to the baffle or location panel. The
use of the foam gasket is advisable
for correct air sealing. For added
performance, and to better reduce
such unwanted vibrations and other
acoustical losses, we recommend
the use of "plain chant". Easily
positioned behind the woofer, on
the metal-work of the vehicle, Plain
Chant soaks-up vibrations as well
as acoustic reflections. Always en-
sure before that enough space is
available for the magnet assembly,
that it doesn't interfere with safety
mechanisms or general working
parts. In the case of not using the
grilles supplied, it is important to
ensure the speakers will fit correctly.
Ensure there is enough depth
behind the speaker has already
been explained,but enough thought
must also be given for the forward
movement of the cone and surround
assembly.
