power handling, and unrivalled

sound quality. To obtain the

best results from this product,

we recommend that you follow

carefully all the information

contained in this user’s manual.

If not followed correctly any fault

observed, may not be covered by

the guarantee.

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

us within 10 days of purchase.

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:

New CMKV sandwich composite,

including (Aramid fiber, 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 Aluminum:

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.

TN53K with inverted tweeter dome:

Inverted dome formed in aramid fiber

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.

Tweeter

The TN 53k 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 prefe-

rences are the outer positions of the

dash board (pic. C, 1), close to the

windshield (pic. C, 2). Normally easy

for installation. The location close to

the door mirror (pic. 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, posi-

tioned ideally high in the doors

(pic. 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 (pic. D, 2), the loss of midrange

can be compensated by adjusting the

crossover (see section “adjustment”

page 7-8).

The woofer-mids from the K2 Power

range can also be placed low in

the “kick-panels” (pic. D, 3) of the

vehicle. This is to further optimise the

stereophonic imaging.

Tweeter surface mounting

Two accessories are suggested for the

surface mounting of the tweeter.

The sole support, with a 30° angle (pic.

E) and the tweeter/woofer support that

has to be adapted to the windshield

upright through transformation (pic.

F). You can divide the box in 2 by

unsticking it or cutting it following the

central axis, this box is also reversible,

you just have to reverse the two flat

parts.

Fitted mounting

Cut out a 50mm diameter opening.

Make the tweeter wires go through.

Adjust the tweeter by pressing on the

side lobes (pic. G).

Attention: It is not necessary to twist

lock the TN53K in place using a

locking tool.To do so, carefully push

and turn on the outer radius wave

guides, turning the tweeter until it is

locked in place.

Woofer and woofer-midrange

recommendations

K2 Power 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 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

If necessary, place the supplied screw

fixing clamps. Fix the round gasket

on the back of the woofer chassis.

Remove the metallic grille from the

rest of the grille. Make the grille holes

coincide with the ones of the driver,

fix with the supplied screws. Stack the

metallic grille (pic. H).

Crossover

To access some crossover settings, you

must remove the translucent cap with

the 4 screws (pic. I).

2-way kit wiring (165 KRX2 and

165 KRXS)

Plug the amplifier output on the “IN”

inputs of the crossover.

Connect the woofer on the “W” output

and the tweeter on the “T” (pic. J).

3-way kit wiring (165 KRX3)

Plug the amplifier output on the “IN”

inputs of the crossover.

Connect the woofer on the “Woofer”

output, the midrange on the “Mid”

output and the tweeter on the

“Tweeter” output (pic. K).

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.
