Tweeter Woofer-midrange Tweeter installation

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.

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).

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.

Woofer and woofer-midrange recommendations

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

2-Way kits connecting up, simple steps

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.

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.

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.

Tweeter level adjustment Staging level adjustment Information of other K2 Power products

Adjustments to the tweeter level, can be made at precise increments, using the selector buttons found inside on the PCB board of the crossover.

These are indicated as -1dB, -2dB and

-4dB. By pushing in one or several of these selector buttons, allows various reductions of level, from -7dB total by

1dB increments (fig. M).

The radiused-profiled wave-guides on the exterior of the TN52 tweeter, can control the directivity of the high frequencies. Thereby, the acoustic energy available can be controlled by the orientation of this radiused profile. This characteristic essentially adds further benefit to the user, to control the staging of the system, or defining better the virtual acoustic imaging of the sound produced.

By simply turning the tweeter and changing the position of the radiused profiles, will modify this staging aspect (fig. N).

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. O, A and fig. P).

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. O, B and fig. P).

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 runningin 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.

Focal-JMlab offer a range of subwoofers from the 13 KS (130mm

/5") to the impressive 46 KX4 (460mm

/18") Consult your dealer for futher information.
