Woofers / midranges mounting
Woofer location
Woofers positioned ideally high
in the doors (fig. 1, A), prod ce
optimal midrange freq encies.
Woofers positioned mid in the
doors are also a sol tion 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 f rther optimize the
stereophonic imaging and staging.
This mo nting only s its 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 vol me
aims at going down to 180Hz.
Mounting advises
Utopia Be woofers and woofer-
midranges have been designed for
a m ltit de of vehicles installations.
It is worth nderstanding the basic
req irements for installing s ch
prod cts. These woofers and woofer-
midranges are abble to deliver
enormo s amo nts of energy, d ring
their positive / negative movement.
Therefore it is imperative that they
be fixed rigid to the desired location
(fig. 3, A). Resin might be sed
(fig. 3, B). The fixing location sho ld
also be strengthened when necessary.
Panels sho ld be strengthened to
eliminate any nwanted vibrations
and screwed on a metallic part
of the vehicle (fig. 3, C). S ch vi-
brations will drastically red ce the
overall performance. These drive
nits sho ld be fixed and sealed
to the baffle or location panel. The
se of the foam gasket is advisable
for correct air sealing. For added
performance, and to better red ce
s ch nwanted vibrations and other
aco stical losses, we recommend
the se of “plain chant”. Easily
positioned behind the woofer, on
the metal-work of the vehicle, Plain
Chant soaks- p vibrations as well
as aco stic reflections. Always en-
s re before that eno gh space is
available for the magnet assembly,
that it doesn’t interfere with safety
mechanisms or general working
parts. In the case of not sing the
grilles s pplied, it is important to
ens re the speakers will fit correctly.
Ens re there is eno gh depth
behind the speaker has already
been explained,b t eno gh tho ght
m st also be given for the forward
movement of the cone and s rro nd
assembly.
