WHICH AUDIO SYSTEM SHOULD YOU CHOOSE?

Every car audio installation requires suitable speakers

You wouldn't choose the same speakers to simply replace the factory ones as you would to build a Hi-Fi system with a DSP or a high-efficiency Show Car installation.

OEM Replacement Easily upgrade the factory audio system.
Hi-Fi / SQ Precision, balance, and soundstage.
SQL / Show Car Efficiency and sound levels for powerful installations.
4 MAIN CATEGORIES

Coaxial, component kit, midrange, or tweeter: which should you choose?

These speakers do not have exactly the same role. The choice depends on the vehicle, the available space, the amplification, and the desired sound reproduction.

Coaxial speakers

A coaxial speaker combines several drivers on the same axis, usually a woofer or midbass driver with a tweeter. It is a practical solution for replacing factory speakers without installing several separate components.

Component kits

A component kit physically separates the woofer and the tweeter. The tweeter can thus be installed higher up in the cabin. 2-way and 3-way kits are particularly interesting for enhancing the soundstage and building a more advanced installation.

Midrange speakers

Midrange, midrange, and midbass speakers reproduce an essential part of vocals and instruments. High-efficiency models are also widely used in SQL, musical SPL, and Show Car installations requiring high sound levels.

Car Audio tweeters

Tweeters reproduce high frequencies. They complement woofers and midrange speakers to provide more detail, presence, and extension in the upper part of the spectrum.

COAXIAL VS COMPONENT KIT

What difference does it make for your car?

The coaxial has the advantage of combining several drivers in a single location. It is therefore particularly suitable when you are looking for a simple installation.

The component kit separates the tweeter from the woofer. This design allows the high frequencies to be placed higher up in the cabin and offers more possibilities for enhancing the soundstage.

However, a component kit is not automatically superior: speaker quality, installation, door treatment, and settings remain crucial.

CHOOSE BY DIAMETER

10, 13, 16.5, or 20 cm car speaker?

The diameter must match your location and the role you want it to play in the system.

10 cm / 4" Small location
13 cm / 5" Compact format
16.5 cm / 6.5" Major format
20 cm / 8" Large surface

10 cm / 4-inch speaker

A compact format used in various factory locations. It is available as coaxial and in certain separate systems.

13 cm / 5-inch speaker

The 13 cm size is a common intermediate format. It allows you to maintain a small footprint while offering many models suitable for OEM replacement or an upgraded installation.

16.5 cm / 6.5-inch speaker

The 16.5 cm size is one of the most common formats in car audio. It is available as coaxial, component kit, woofer, midrange and midbass, with very different power levels.

20 cm / 8-inch speaker

With a larger cone surface, the 20 cm size is found in midbass systems, high-efficiency speakers, and certain custom installations.

3.5" • 4" • 5" • 6.5" • 8" • 12" • 4x6" • 5x7" • 6x8" • 6x9"

Round formats and oval speakers

The range includes many round formats, but also oval speakers such as 4x6", 5x7", 6x8", 6x9", and certain more specific formats.

Note: two speakers listed with the same diameter do not necessarily have the exact same dimensions. Check the mounting diameter, mounting depth, mounting hardware, and the space available behind the speaker.

Diameter alone does not determine performance.

A larger speaker generally has more cone surface, but its reproduction also depends on its motor, cone, excursion, sensitivity, filtering, and installation.

CAR TWEETERS

Hi-Fi, dome, bullet, or high-power tweeter

Tweeters come in very different designs depending on whether the goal is sound quality, efficiency, or maximum sound level.

Hi-Fi / SQ tweeter

These models are particularly suitable for installations seeking precision, detail, and integration into a balanced soundstage.

Bullet tweeter

Bullet tweeters are frequently used in high-efficiency installations. Their design is focused on high efficiency and significant projection.

Compression / horn tweeter

Compression and horn solutions are used when high efficiency and strong projection are required, particularly in certain Show Car and high-power systems.

SPL / SQL tweeter

In an installation equipped with many midrange speakers or a very powerful low-end section, high-efficiency tweeters maintain a sufficient level in the high frequencies.

TWEETER FILTERING • CROSSOVER • DSP

A tweeter must be correctly filtered

A tweeter is not designed to reproduce low frequencies. A high-pass filter or suitable crossover allows you to limit the frequencies sent to the tweeter.

The crossover frequency and slope must be adapted to the model used. In an active installation, a DSP allows you to precisely set the crossovers, levels, equalization, and delays.

Do not connect a full-range tweeter without checking its filtering.

Frequencies that are too low can cause excessive excursion or overheating and damage the tweeter. Always follow the manufacturer's recommendations.

MIDRANGE • MIDRANGE • MIDBASS

What is the difference between midrange and midbass?

These terms describe speakers whose operating ranges may overlap, but whose goals are not always identical.

Midrange / midrange

Midrange reproduces an essential part of vocals and instruments. In high-power installations, high-sensitivity models allow you to achieve a high sound level with controlled power.

Midbass / midbass

A midbass is generally intended to go further down into the low end and produce more kick. The exact operating range, however, depends on each speaker.

SQ • SQL • SPL • SHOW CAR

Not all speakers are designed for the same goal

An SQ installation generally prioritizes fidelity, tonal balance, and soundstage.

An SQL installation seeks to maintain musical reproduction while achieving a high sound level.

Demonstration-oriented or musical SPL systems may use multiple midrange speakers and high-efficiency tweeters to match a particularly powerful subwoofer section.

RMS POWER

40 W, 60 W, 100 W, 150 W, 200 W RMS and more

Our selection covers very different power levels, from speakers designed to run on a car stereo to midrange speakers and tweeters designed for heavily amplified installations.

30–60 W RMS Simple installation
60–100 W RMS Versatile car audio
100–200 W RMS Amplified system
200 W RMS+ High power
200 W RMS does not automatically mean a speaker plays louder.

RMS power mainly indicates power handling capability. Sound level also depends on sensitivity, amplification, filtering, the frequency range used and the acoustic installation.

SENSITIVITY • DB • EFFICIENCY

Why is sensitivity important?

Two speakers displaying the same RMS power can produce different sound levels. Sensitivity gives an indication of the efficiency with which the speaker converts electrical power into acoustic output.

To properly compare several references, you must, however, take into account the conditions under which the values were measured.

IMPEDANCE

2, 3, 4, 6, or 8-Ohm speakers

Impedance is an essential element to ensure compatibility with your car stereo or amplifier.

Simple installation

To replace an original speaker, check the impedance of the existing system and the compatibility of the new speaker with the OEM head unit or amplifier.

Multi-speaker installation multi-speaker

When multiple speakers are wired to the same channel, the series or parallel wiring changes the final impedance seen by the amplifier. This load must remain compatible with the amplifier used.

HEAD UNIT OR AMPLIFIER

Do you need an amplifier to change your speakers?

Not necessarily. Many coaxial speakers and component kits can work with a head unit.

An external amplifier becomes particularly interesting for speakers with a higher power handling capacity and to provide more dynamic headroom.

Always compare the actual RMS power delivered by the amplifier to the impedance used.

An amplifier's gain is not a power or volume knob.

It is used to match the amplifier's input sensitivity to the source signal level. Incorrect setting can promote clipping and increase the risk of damaging the speakers.

ACTIVE SYSTEM & DSP

Take it to the next level with a DSP processor

A DSP allows you to precisely control each channel and becomes particularly interesting in advanced multi-way installations.

Filtering HPF, LPF, and frequency bands tailored to each channel.
Equalization Correct the system's response in the cabin.
Time Alignment Work on the placement and coherence of the soundstage.
BUYING GUIDE

How to choose your car speakers?

Before choosing by brand or wattage, check the characteristics that are truly important for your installation.

✓ Type — coaxial, component kit, midrange, midbass, or tweeter
✓ Diameter — check the available mounting space
✓ Depth — measure the space behind the speaker
✓ RMS Power — match your amplification
✓ Sensitivity — important for efficiency
✓ Impedance — check the amplifier's load
✓ Frequencies — choose the appropriate range
✓ Filtering — passive, amplifier, or DSP
INSTALLATION • DOORS • SOUND DEADENING

A good speaker deserves a good installation

A car door is not a perfect acoustic enclosure. Vibrations, leaks, and overly flexible supports can limit the speaker's performance.

A rigid mounting bracket, proper fastening, and appropriate acoustic treatment can improve the performance of the midrange and reduce certain parasitic vibrations.

FREQUENTLY ASKED QUESTIONS

FAQ – Car Speakers & Tweeters

Which speakers should I choose to improve my car's sound?

First, check the dimensions and impedance of the stock system. For a simple installation, a coaxial may be suitable. A component kit offers more possibilities for working on tweeter placement and the soundstage.

What speaker size should I choose?

10, 13, and 16.5 cm formats are very common, but the correct size depends on the vehicle. Check the cutout diameter, depth, and mounting.

What is the difference between coaxial and component kits?

The coaxial combines several drivers in the same location. The component kit separates the woofer and tweeter so they can be positioned independently.

What is the difference between midrange, midbass, and tweeters?

The midbass generally works at lower frequencies and provides kick, the midrange reproduces much of the vocals and instruments, while the tweeter completes the high frequencies.

Do you need an amplifier for new speakers?

Not necessarily. Some models work with a head unit. However, a suitable amplifier allows you to better utilize speakers that require more power.

How do I choose an amplifier's power?

Compare the speakers' RMS power with the RMS power delivered by the amplifier at the correct impedance. Do not base the choice on MAX or Peak values.

Does a 200 W RMS speaker play louder than a 100 W RMS?

Not necessarily. Sensitivity, efficiency, frequency range, installation, and actually applied power also influence the sound level.

Must a tweeter always be filtered?

Yes, it must be protected from frequencies that are too low with filtering suited to its characteristics and the manufacturer's recommendations.

What is a Car Audio DSP used for?

A DSP allows you to manage filters, equalization, levels, and delays for each channel to optimize the system in the cabin.

Should the doors be soundproofed?

It is not mandatory, but rigid mounting and appropriate acoustic treatment can reduce certain vibrations and improve the performance of speakers installed in the doors.

Can you install multiple midrange speakers on the same amplifier?

Yes, provided that the wiring produces an impedance compatible with the amplifier and that the available power is suited to all the speakers.
