COAXIAL • 2-WAY • 3-WAY • CAR SPEAKER

Car coaxial speakers easily upgrade your audio system

Discover our Car Audio coaxial speakers in 8.7 cm, 10 cm, 13 cm, 16.5 cm and oval 4x6, 5x7, 6x8 and 6x9 inch formats. A practical solution to replace factory speakers and improve the sound in your car.

CAR COAXIAL SPEAKER

Multiple ways combined in a compact speaker

A car coaxial speaker combines several acoustic ways on the same axis. A 2-way model generally combines a woofer or mid-bass driver with a tweeter in order to cover an extended frequency range with an installation simpler than a fully separate system.

10 cm / 4" Compact format
13 cm / 5" Versatile
16.5 cm / 6.5" Very common format
6x9" Large surface
CAR AUDIO REPLACEMENT

A simple solution to upgrade factory speakers

Coaxial speakers are particularly interesting for replacing a factory system without multiplying components. Several ways are grouped in a single speaker while retaining many formats suitable for automotive locations.

Simple installation Woofer and tweeter combined on the same speaker.
Many formats Round and oval for many vehicles.
Wide choice From OEM replacement to amplified system.
CHOOSE BY DIAMETER

10, 13 or 16.5 cm coaxial speaker?

The diameter depends mainly on the available space in your vehicle. Also check the depth, mounting diameter and fixings before ordering.

8.7–10 cm 3.5" / 4"
13 cm 5 inches
16.5 cm 6.5 inches
6x9" 15x22 cm

Coaxial speaker 10 cm / 4"

10 cm coaxials are suitable for small locations found in many vehicles. They allow replacing a compact speaker while retaining a discreet installation.

Coaxial speaker 13 cm / 5"

The 13 cm format is an excellent intermediate. It is available in many power ranges for factory replacement or an improved Car Audio installation.

Coaxial speaker 16.5 cm / 6.5"

The 16.5 cm is one of the most common formats in Car Audio. Its larger cone surface than small formats generally allows it to offer more capacity in the mid-bass, depending on its design and installation.

Coaxial speaker 6x9 inches

The 6x9" is an oval speaker offering a large cone surface. It is particularly common in certain rear shelves and in vehicles having suitable locations.

3.5" • 4" • 5" • 6.5" • 4x6" • 5x7" • 6x8" • 6x9"

Coaxial speakers in many formats

Find round coaxial speakers of 8.7 cm, 10 cm, 12 cm, 13 cm and 16.5 cm as well as oval formats 4x6", 5x7", 6x8", 6x9" and other dimensions.

Attention: the nominal diameter does not guarantee by itself compatibility with your car. Also check the depth, mounting diameter and fixings.

2-WAY & 3-WAY

2-way or 3-way coaxial: what difference?

2-way coaxial speaker

A 2-way coaxial generally combines a woofer or mid-bass driver with a tweeter mounted on the same axis. It is a very common architecture to replace factory speakers.

3-way coaxial speaker

A 3-way model adds an additional way to further distribute the spectrum reproduction. However, the number of ways does not determine by itself the sound quality of the speaker.

30 W • 40 W • 50 W • 60 W • 70 W • 80 W • 90 W • 100 W RMS+

What power for coaxial speakers?

Our selection covers many power levels: 30 W, 40 W, 45 W, 50 W, 55 W, 60 W, 65 W, 70 W, 75 W, 80 W, 90 W and 100 W RMS or more depending on the references.

To choose correctly, compare the RMS power rating of the speaker with the power actually delivered by your car stereo or your amplifier at the correct impedance.

Do not choose your speakers solely by Watts.

RMS power corresponds mainly to the power handling capacity. Sensitivity, frequency response, speaker design, door mounting and amplification also strongly influence the sound result.

CAR STEREO OR AMPLIFIER?

Should coaxial speakers be amplified?

It depends on the chosen model and the desired performance level. Some coaxial speakers work perfectly with a car stereo while more powerful models will benefit more from an external amplifier.

Coaxials with car stereo

For a simple installation without an amplifier, look for speakers whose characteristics are consistent with the power available on your car stereo.

Coaxials with amplifier

An external amplifier offers more available power and allows to better exploit speakers designed to accept a higher RMS power.

COAXIAL OR COMPONENT KIT?

Two different solutions to improve the sound in your car

The coaxial speaker groups the different ways in the same place, which generally facilitates installation.

A component kit notably separates the woofer and the tweeter. It thus allows to position the highs at another place in the cabin and offers more possibilities to work the soundstage.

For a simple replacement, coaxial is often an excellent solution.

If your goal is to quickly replace the factory speakers while improving reproduction, a good pair of coaxials can offer an excellent compromise between simplicity, space, budget and performance.

BUYER'S GUIDE

How to choose your car coaxial speakers?

Before choosing a brand or power, start by checking the dimensions and characteristics of your installation.

✓ Diameter — 10, 13, 16.5 cm or oval format
✓ Depth — check the space behind the speaker
✓ Fixings — a spacer may be necessary
✓ RMS Power — match the source or amp
✓ Impedance — check electrical compatibility
✓ Use — OEM, Hi-Fi or amplified Car Audio
SPEAKER INSTALLATION

Take care of the mounting to get a better result

Even an excellent speaker can lose part of its potential if it is poorly mounted. A suitable spacer, rigid mounting and acoustic treatment of the door can significantly improve the system's performance.

OEM Replacement Simply replace your factory speakers.
Hi-Fi Installation Choose good coaxials and take care of their mounting.
Amplified Car Audio Exploit the more powerful models with a suitable amp.

FREQUENTLY ASKED QUESTIONS

FAQ – Car coaxial speakers

What is a coaxial speaker?

It combines several acoustic ways on the same axis, generally a woofer or mid-bass driver associated with a tweeter.

What speaker diameter should I choose for my car?

Check the factory location: diameter, mounting depth and fixings. The 10, 13 and 16.5 cm formats are very common.

What difference is there between 2-way and 3-way coaxial?

The 2-way generally uses a woofer and a tweeter. The 3-way adds an additional way, but the number of ways is not enough to determine sound quality.

Coaxial or component kit: which one to choose?

Coaxial simplifies installation. The component kit separates notably the woofer and the tweeter, which allows more freedom for their positioning.

Can coaxial speakers be connected directly to a car stereo?

Yes for many models, provided their impedance is compatible. The available power will however generally be lower than that of an external amplifier.

Is an amp needed for 100 W RMS speakers?

A suitable external amplifier generally allows to better exploit their potential. Always compare the RMS power at the correct impedance.

What difference is there between 13 cm and 16.5 cm?

The 16.5 cm has a larger cone surface. The result nevertheless depends on the speaker design, its mounting and the acoustic installation.

What does 6x9 inch speaker mean?

It is an oval-shaped speaker belonging to the category commonly called 15x22 cm in Car Audio.

Are spacers needed to change the speakers?

It depends on the vehicle. Some locations require a spacer or an adapter in order to correctly mount a universal speaker.
