Focal ES 130 K Component Speaker Kit

Focal ES 130 K is a 130 mm component speaker kit for in-car audio systems. It reproduces low and high frequencies through separate drivers and uses an external crossover. Its nominal 80 W RMS power rating and 4 Ω impedance are the main specifications to consider when choosing an amplifier.

This is not a coaxial speaker system. The separate TKM tweeter can be installed in a more suitable position inside the vehicle. This component speaker arrangement makes it possible to shape the front soundstage more precisely.

Who this kit is for

This kit is intended for a car audio system in which the main drivers and tweeters are installed separately. It is suitable for use with a car amplifier designed for a 4 Ω load or with a compatible head-unit amplifier.

The nominal 130 mm diameter identifies the general installation size, but it does not describe every physical dimension. Before installation, measure the opening, mounting points and available depth. These checks are particularly important when fitting speakers in vehicle doors.

Cone, suspension and tweeter

The main driver uses a composite K2 Power W multilayer cone. This layered construction is designed to balance cone rigidity with mechanical damping. That balance is important when one driver is responsible for reproducing both low and midrange frequencies.

The suspension incorporates Tuned Mass Damper technology. It is designed to control suspension resonances when the cone moves through greater excursions. This construction works together with a voice coil measuring 25 mm in diameter and 12 mm in height.

The TKM tweeter features an inverted aramid-fibre dome with an M-shaped profile. Because it is installed separately, it can be positioned and aimed toward the listeners. The final tonal balance can then be adjusted using the tweeter-level setting on the crossover.

Crossover and connections

The amplifier’s speaker output connects to the separate crossover. The crossover divides the signal between the main driver and the tweeter. The store’s product data lists its characteristic as 6-12/12 dB at 3.5 kHz.

The speakers on both sides of the vehicle should be connected with matching polarity, following the markings on the crossover. Reversing the polarity of one speaker can weaken the centre image and reduce bass reproduction. Speaker cables should also be routed away from potential sources of electrical interference where possible.

The amplifier must be suitable for a 4 Ω load. When selecting amplifier power, the nominal 80 W RMS rating is more relevant than the 160 W maximum-power figure. The maximum rating does not describe continuous operating power.

Adjusting the tweeter level

The crossover provides +3, 0 and -3 dB tweeter-level settings. Begin the initial setup at 0 dB. This gives you a neutral reference point from which to compare the other two positions.

If the tweeters are installed low in the cabin or aimed away from the listeners, try the +3 dB setting. If they are mounted close to ear level, the -3 dB position may be more suitable. Make the final assessment while seated in your normal driving position.

Power, sensitivity and frequency range

The stated 90 dB sensitivity was measured at 2.83 V from a distance of one metre. This measurement condition should be kept in mind when comparing the kit with other speakers. For a 4 Ω load, sensitivity figures measured at 1 W and at 2.83 V are not directly equivalent.

The reproduced frequency range extends from 65 Hz to 22 kHz. The 65 Hz lower limit indicates that this kit is not intended to reproduce the deepest sub-bass. A separate subwoofer can complement the system when lower-frequency extension is required.

Installation in a vehicle

The main drivers are usually fitted in the doors or in factory 130 mm speaker positions. A rigid mounting surface and a well-sealed fit help the speakers deliver their available bass performance. The door trim must not touch the moving parts of the cone or suspension.

The tweeters should be installed symmetrically on both sides of the cabin. Their direction has a strong effect on the perceived amount of high-frequency output. Test their angle first, then fine-tune the level using the crossover.

An earlier version of the store description stated that protective grilles were included, but the current package contents should be checked before purchase. Grilles are useful when the main drivers are installed in exposed or easily accessible positions. In factory door locations, whether they can be used depends on the vehicle’s existing trim.

Technical specifications

FAQ

Are these coaxial speakers?

No. The main drivers and tweeters are installed separately, and the external crossover divides the signal between them.

What amplifier does this kit require?

The amplifier must be able to operate with a 4 Ω load. Choose its power according to the nominal 80 W RMS rating and avoid sending a distorted signal to the speakers.

Can the kit be connected directly to a car head unit?

Yes, but only if the head unit’s amplifier is designed for 4 Ω speakers. Its actual power per channel will determine the attainable volume.

Which tweeter-level setting should I choose?

Choose +3 dB when the tweeters are installed low or aimed away from the listener. The -3 dB setting may be preferable when they are positioned close to ear level.

Is a subwoofer necessary?

The kit reproduces frequencies from 65 Hz. Add a separate subwoofer if you want deeper sub-bass reproduction.

Does the 130 mm diameter guarantee that the speakers will fit my car?

No. You must also check the mounting opening, available depth, fixing points and clearance behind the door trim.

Are these speakers intended for a home stereo or cinema system?

They are designed for car audio systems. A home amplifier may be used only if it is suitable for a 4 Ω load.
