Most car and music enthusiasts would love nothing more than to have the highest quality music, no matter what they drive. Even if you have a small car, the best 5.25 component speakers will pack a big sound punch!

Let’s face it. Our cars do not always have the space that a complete car audio system requires. But that doesn’t mean we have no choice but to deal with a sub-par car audio system.

Coaxial and component speaker systems both offer two and three-way systems. They are smaller than other types of units. Let’s learn about the differences between component and coaxial speakers.

What are component and coaxial speakers?

When most of us think about professional quality car audio systems, we most often imagine large speakers that take up a good portion of a large trunk, as well as other places within the cab of the vehicle.

Many people drive compact or small sports cars and either don’t have the space to give up, or need to maintain the ability to haul a load of groceries.

This doesn’t mean that you can’t have a great sounding car audio system, even if you have a small car or limited internal space. There are two-way and three-way speakers that are all-in-one systems that comprise all the parts you need.

Two-way systems consist of a tweeter and a subwoofer. Three-way systems consist of a tweeter, subwoofer, and midrange speaker. These are space-saving systems that give you the ability to get big car audio sound out of a small unit.

There are a couple of similarities in both component and coaxial speakers. Both of them can be either two or three-way systems. They are also both space-saving systems, which will deliver a loud and powerful sound from a 5.25” speaker.

The main difference, at least in physical construction, is the configuration of the different speakers in the system.

Coaxial speakers are often the most affordable of the two options, and are also the most common type of speaker. A good portion of stock car audio systems are coaxial speaker systems. Sometimes a coaxial speaker system is also called a full-range system.

The basic configuration of the full-range, coaxial system is that the tweeter (which reproduces high frequency sounds) is mounted to the cone of the woofer (which is what reproduces bass and low frequency sounds).

The main reason for this configuration has nothing to do with function or performance; it is merely a space-saving measure. These systems are called full-range systems because they can reproduce sounds across the entire range of sound frequencies.

One of the pitfalls of this configuration is that there is an increased risk for interference and feedback due to the closeness of the two types of speaker.

What is really being referred to when we say two, three, or even four-way systems is more than just the number of speakers or drivers. Obviously, the more drivers you want, the higher quality of sound you get, but the price tag goes up as well.

Regardless, there are a couple of big perks to the coaxial system. Firstly, this system is more affordable than component systems. Many also like that they are relatively simple to install. Component systems can be a bit trickier when it comes to installation.

Component speakers offer the same space-saving benefits of coaxial speakers, but they have a different configuration that helps to optimize the quality of the sound produced from such a small system.

Component systems are sometimes called separates, as the different components are not mounted to each other like they are in coaxial units.

Unlike coaxial units, component systems tend to double up on each element; this means there are usually two tweeters, two subwoofers, and two crossovers. This gives a fuller, richer, more vibrant sound quality to the system.

There are three-way component systems that also have mid-range speakers. This further enhances the depth and fullness of the sound quality.

As with larger units, the tweeters in component systems handle the higher frequency sounds. Mid-range speakers handle mid frequencies, and woofers cover low-range frequencies like bass.

One of the perks of this type of system, apart from the enhanced sound quality, is that these systems can be added to. So called “super tweeters” and “super subwoofers” can be added to create more powerful bass and more powerful sound.

Basically, with the component speaker system, you have the potential for better sound quality. However, there are coaxial systems that have excellent sound quality.

There are more options available with component systems, but they tend to cost more. Component systems are advanced and more difficult to install than coaxial systems.

There are benefits and downsides to both of these systems, but either is a great choice for someone looking to get big sound out of small spaces.
