Features
Membrane K2 Power:

New 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.

TN 52 with inverted tweeter dome:

Inverted dome formed from titanium
treated Tioxid 5 material. Producing
detailed high frequencies, acoustically
rich and dynamic. Controlled with
twin radius wave guides, for totally
controlled staging and directivity.

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 TN52 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. A, 1), close to the
windshield (fig. A, 2). Normally easy
for installation. The location close
to the door mirror (fig. A, 3) is also
regarded as a good position, and
normally only requires a small amount
of install work. Lastly a position high in
the doors (fig. A, 4) is also acceptable
even if it is not considered the best for
optimised staging. It is imperative
to verify before any installation is
attempted, that enough space is
available (especially for flush-mount
applications). Also that there will be
no interference with security devices
air-bags, door latches etc.

Woofer-midrange

K2 Power woofer-midranges, posi­tioned ideally high in the doors
(fig. B, 1), produce optimal midrange
frequencies, thus integrating better into
the rest of the system. The 100 KP Slim
thanks to its reduced depth feature
allows easy installation into the outer
positions of the dashboard (fig. B, 2).
If the woofer-mids are positioned
low in the doors (fig. B, 3), the loss
of midrange can be compensated by
adjusting the crossover (see section
"adjustment" page 15).
The woofer-mids from the K2 Power
range can also be placed low in
the "kick-panels" (fig. B, 4) 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 KP
Slim, has obvious advantages. With
minimum depth dimension 39mm
(1.58"), due to its efficient neodymium
motor, the 100 KP is ideal for centre
channel applications, in normally
difficult locations such as the dash
board (fig. C).

Tweeter installation
Surface-mount

The flush-mounting fixing kit supplied
offers two possibilities for installing
the TN52 in an angle of 10°/30°.
This allows more flexibility for the
installation (fig. D).
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. E).

Attention: It is not necessary to twist
lock the TN52 in place using a locking
tool (as for TN47).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. F). 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.
Fix the foam gasket to the back of the
drive unit chassis. Add a small amount
of glue where necessary, so it remains
in the correct position (line-up holes).
Lower the drive unit above the fixing
ring, so it remains in the correct
position (line-up holes).
Don’t forget to connect up the cable
to the connectors.
Now lower the drive unit and screw in
place, with the 4 screws provided.
Now add the grille and push in place.
Ensure the logo is straight.

Crossover installation, simple steps

First before any work is started it is
necessary to remove the clear plastic
lid (fig. G).
Doing so enables access for
adjustment, and fixing the unit in
place.
Remove, by pushing gently on the two
shortest sides of the clear plastic lid.
Then pull off.
Never use a screwdriver to prise
off the lid, otherwise damage will
probably occur, not covered by the
warranty.
Once removed, fix in place with the
4 screws supplied. Ensure the length
of screw is suitable for the desired
location. Always ensure the crossover
is installed in a dry and vented area,
without risk of humidity.

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. H).
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.

3-Way kits connecting up (165 K3P)

The 165 K3P uses two crossovers,
connected together. The exclusive
165 KBP low frequency cross-over,
has two configurations for filtering.
These being mode:
"High Pass" (fig. I, and K), for a true
3 way set-up, with separate bass mid
and high frequencies.
"Full" (fig. J, and L), for a 2+1 way
set-up, with 2x165mm in parallel, for
more dynamic fast bass.

Important (165K3P)

Depending on the preferred set-up,
the selector found in the 165KBP, must
be switched accordingly.
The mode "Full" (F),requires inverting
the connections, for input (fig. I, and J).
Doing this will ensure the overall
phase will remain correct. Because
this mode has a low impedance value
of approximately 2 ohms, verify if the
low loading is compatible for your
amplifier.
