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.

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.
