Warning

Continued listening at high volume
levels above 110dB, are damage your
hearing durably
Listening above 130dB can damage
your hearing permently.

The Focal-JMlab guarantee
only applies if the enclosed
guarantee card is returned to

Information

We make different measure types
on baffle plan of our speakers and
crossovers in order to guarantee the
best settings according to the placing
of your loudspeakers (fig. A). For a
use on a display shelf, we recommend
the crossover settings as follow:
tweeter level at 0dB, woofer in Flat
mode and filtering slope at 18dB/oct.
for the kits that have this function (fig.
B). For any installation in your vehicle,
please refer to the remainder of the
user manual.

Features
Membrane K2 Power:

CMKV sandwich composite, including
(Kevlar, foam, and structural glass
fibre). Three individual materials,
each with their own advantages,
allow the cone to be extremely rigid,
with continued low mass value, and
increased damping characteristics,
even when played loud. This ensures
improved power handling, with
detailed sound quality, low distortion
even at high volume levels.

Chassis made from Zamak:

Inherently rigid and non magnetic.

Voice coil wound on Kapton former:

Light-weight and highly durable
material ensures no deformation of
voice coil.

Butyl moulded rubber surround
suspension:

Long life characteristics, even in the
most extreme climates.

TNK with inverted tweeter dome:

Inverted dome formed from kevlar
material. Producing detailed high
frequencies, acoustically rich and
dynamic.

Crossover of high precision:

Precise level adjustment of tweeter
and medium available. High
quality audiophile components
used throughout. Large wire gauge
connections included.

Installation and positioning

Tweeter

The TNK tweeter has been designed
for flush mount or surface mount
positioning, using the two fixing kits
provided. The choice of install position
is extremely important to deliver
the best performance and maintain
integration into the system. This is a
major factor for high frequency SPL,
and the the stability of the acoustics,
stereophonic imaging, and overall
staging. Please check the drawing to
understand this further.
The standard recommendation for
ideal stereo imaging, is to ensure the
tweeters "left" and "right", are installed
in the same positions. Also they are
approximately at equal distance to the
driver (vice-versa for the passenger).
The various positions advised should
be verified and comparatives made,
for ideal positioning.
The tweeter should always be
positioned ahead of the normal
listening position. The main prefe­rences are the outer positions of the
dash board (fig. C, 1), close to the
windshield (fig. C, 2). Normally easy
for installation. The location close
to the door mirror (fig. C, 3) is also
regarded as a good position, and
normally only requires a small amount
of install work.

Woofer-midrange

K2 Power woofer-midranges, posi­tioned ideally high in the doors
(fig. D, 1), produce optimal midrange
frequencies, thus integrating better
into the rest of the system. If the
woofer-mids are positioned low in the
doors (fig. D, 2), the loss of midrange
can be compensated by adjusting the
crossover (see section "adjustment"
page 6).
The woofer-mids from the K2 Power
range can also be placed low in
the "kick-panels" (fig. D, 3) of the
vehicle. This is to further optimise the
stereophonic imaging.

Centre Channel

Ideally suited for an audio video
installation using DVD multi channel
inputs (Dolby Digital, DTS etc), the
ultra compact midrange 100 KRS, has
obvious advantages. With minimum
depth dimension 39mm (1.58"), due
to its efficient neodym motor, the
100 KRS is ideal for centre channel
applications, in normally difficult
locations such as the dash board (fig.
E).

Tweeter installation
Surface-mount

The flush-mounting fixing kit supplied
offers two possibilities for installing
the TNK in an angle of 10°/30°.
This allows more flexibility for the
installation (fig. F).
Fix the assembly using the two screws
provided. Thread the cable from the
tweeter, through the back.
Then decide the defined angle and
lock in place on the support.

Flush-mount
(highly recommended)

Cut a perfectly round hole of 45mm
(1,77“) Push in the support and ensure
it remains flat on the surface. Ensure
it is locked in place with the screws
supplied. Thread the cable from the
tweeter, through the back. Then decide
the defined angle and lock in place
the tweeter on the support (fig. G).

Attention: It is not necessary to twist
lock the TNK in place using a locking
tool (as for TNK).To do so, carefully
push and turn on the outer radius
wave guides, turning the tweeter until
it is locked in place.

Installation and positioning

Woofer and woofer-midrange
recommendations

K2 Power woofers and woofer­midranges have been designed for
a multitude of vehicles installations.
It is worth understanding the basic
requirements for installing such
products. These woofers and woofer­midranges are capable of delivering
enormous amounts of energy, during
their positive/negative movement.
Therefore it is imperative that they
be fixed rigid to the desired location.
The fixing location should also
be strengthened where necessary.
Panels should be strengthened to
eliminate any unwanted vibrations.
Such vibrations 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 ensure 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. Ensuring
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.

Woofer and woofer-midrange
installation, simple steps (with grille)

Either cut the required hole or use the
correct hole of choice. Note correct
diameter (fig. H). Where necessary,
carefully push in the four fixing clips to
accept the fixing screws later.
Carefully place the fixing ring, ensuring
it lines-up with the holes or fixing clip
positions.

Crossover installation, simple steps

Remove the translucent cover thanks
to the 4 screws to accede to the
different suggested settings.
Tightly fix the crossover thanks to the
2 supplied screws on an adapted
support in the vehicle. The crossovers
must be installed in a dry and well­ventilated place (preferably without
vibration). (Fig. I)

2-Way kits connecting up, simple
steps

Connect the output from the amplifier
into the input of the crossover "IN".
Connect the woofer to the output of
the crossover "W".
Connect the tweeter to the output of
the crossover "T" (fig. J).
Finally always ensure the tweeter
and woofer are connected in phase
correctly, thus polarities are respected
"+" to "+", and "-" to "-". If not done
correctly a "hole" or "peak", may
result, due to a shift in phase. This
will dramatically impair the overall
performance.

Fine tunning / set-up

Tweeter level adjustment

The tweeter level setting goes off inside
the crossover, through the right switch
and permits 3 setting levels (fig. K).

Midrange level adjustment

The crossover contains a specific
level adjustment for the midrange
frequencies.
Fitting the drive units high up in the
vehicle requires the mode " Mid flat "
to be used. Doing so will ensure the
overall response curve of the system
remains linear (fig. D, 1 and fig. L).
Fitting the drive units low in the vehicle,
especially in the bottom of the door
for example, requires the mode "Mid
High" to be used. Doing so will ensure
such normally directional frequencies
are not "masked" or lost in the textiles
of the vehicle (fig. D, 2 et 3 and fig. L).

Running-in period

K2 Power drive units use the very
latest components. To ensure such
complex mechanical elements work
in harmony with each other, they
must be allowed to function correctly
in this environment. Such changes
in temperature and humidity are
regarded as very hostile. For K2 Power
speakers to benefit, a running-in
period must be used to ensure they
are prepared for this. We recommend
that once the system is ready for
listening the drive units should be
run-in with medium volume setting,
with music that has the full bandwidth
of frequencies (sub-bass through to
treble). This running-in period should
be used for a few weeks, to gain the
full potential. After which the excellent
performance of your K2 Power
products can be fully appreciated.
