  • Have a shallow mount design which eliminates the worry of hitting a glass or any other sensitive obstruction.

What We Didn’t Like

  • The magnet is small which affects the overall quality of the sound.

These are typical 2-way speakers. With midrange drivers that outputs the midbass and midrange frequencies of your favorite music and one tweeter on the coaxial unit, you can hear music the way it is supposed to be heard. These are all done by the propylene cones and 1 balanced-dome tweeter.

These speakers also have an impedance of 4 ohms which means this speaker is high end and will require a modest amplifier. It will also give you more opportunity to incorporate other components into the system without any doubt of failing.

The tweeters are patented and unipivoted so that you can aim the tweeters in your direction of choice or most probably towards your ears. This will work perfectly even when you have your speakers down in your doorway. To make it even more lovable, they have added a dual level volume adjustment for the twitter that will compensate for minor flaws in the speaker placement.

They are low impedance speakers of 3 ohms which makes them great with the undersized factory wires of your car. This will work perfectly especially if you are not aiming at changing the wiring system.

What’s more, they have a 12dB/octave inbuilt crossover that helps the speaker channel the right frequencies to the right components.

What We Like

  • Made with plus one cones that are carbon injected hence more bass.
  • Unipivot tweeters that will allow customized direction.
  • Comes with dual-level tweeter volume that helps compensate for inappropriate speaker placement.
  • Has low impedance hence works well with lowly rated factory wires.
  • Comes with a sensitive crossover that helps channel the frequencies to the midrange drivers and the tweeters.

What We Didn’t Like

  • Made of plastic arms that easily break.

What makes these speakers outshine is how they use balance technology to deliver signature quality sound. The base is captured through the use of a polypropylene and UV tolerant cone. To ensure that they remain safe while you drive through rain and other unlikely conditions, they are covered by waterproof surrounds. What completes these speakers are the lavish removable sports grilles.

They have a sensitivity of 92dB that is determined by 1 watt at the 1-meter rule. This means that these speakers fall into the category of the best sounding 6.5 car speakers. To ensure that you don’t miss the low frequency that is the bass, these speakers are designed in a special way that allows them to capture frequencies as low as 40Hz leaving more room for your subwoofer.

On the other hand, they can play highs of up to 22 kHz through the tweeters. What’s more, they have a power handling capacity of 300W peak power and RMS of 100 watts which makes them less straining on the amplifier.

What We Like

  • Works on balance technology deliver signature sound.
  • It is marine certified.
  • Uses highly sensitive polypropylene and UV tolerant cone.
  • It has waterproof surrounds.
  • Comes with removable sports grilles.

What We Didn’t Like

  • The tweeters are much exposed and hence can break.

You will love these coaxial speakers; they are easy to mount. You can mount them to a depth of 146 mm.  They are 2-way speaker meaning that you will have the midrange drivers that will handle frequencies from 50Hz to 2 kHz and the rest of the frequencies go to the 20mm Neodymium Tetolon dome tweeter.

With a sensitivity of 92 dB, it means the speakers do not require much power to convert signals to sound. If you are going to use an amplifier on this speaker, then it won’t outwork your amp as it has an impedance that falls in the range of that of high-end speakers, 4 ohms. To make it even safer, it has wattage ratings of 100-200 watt

The cone is a damped mesh fiber that will vibrate and magnify the sound from the coil which is in this case pure copper that is wound on a KSV former. On it are also anti-vibration rubber magnet covers. To ensure that the coil that does get worn off as the speaker vibrates is kept in place, it is surrounded by a loss-less polymer rubber surround.

What We Like

  • Has a high-end tweeter.
  • It will cover more of the stereo field since it has a frequency response of 50Hz to 22 kHz.
  • Has low impedance which means it does not consume much power and won’t overwork the amplifier.
  • It has a high sensitivity hence low power use for sound conversion.
  • The cone is reinforced with rubber surrounds for durability.

What We Didn’t Like

  • The tweeter precise positioning feature is likely to fail to make directional positioning hard.

At times music lovers are caught in between deciding what to go for. Even if they have made up their mind, they are still stuck in understanding why they have chosen a specific type of speakers. Let’s get to understand more about speakers first.

Speaker Drivers

Speaker Drivers

#1- Woofer

These are speaker drivers responsible for low or bass frequencies. They have a frequency range of between 20Hz to 1000Hz. They are responsible for driving the frequencies that human ears struggle to hear. For some woofers with midrange drivers incorporated in them, they can cover up to 5 kHz.  

There is also a special kind of woofers called subwoofers. These woofers are responsible for playing frequencies in between 20 Hz up to 120 Hz. They are normally installed as a component separately from the other components which means for a system running this kind of woofers; it must have a crossover.

#2- Mid-range

As its name suggests, they are responsible for playing frequencies in between 200Hz to 12,000Hz. These are the frequencies that most of the musical instruments are played at. If you have a midrange speaker, it will still sound flat and without the high notes and the low notes. That is why a woofer and the next driver are necessary.

#3- Tweeter

Tweeters are responsible for outputting the high-end frequencies which most of the time include hi-hats, whistles, white noise, bells, etc. In technical terms, they operate in between the frequencies of 2 kHz to 20 kHz.

Since musical frequencies vary from one end to another, a tweeter will not be playing the whole song, but it will be heard bursting shots of these high frequencies adding a more life to the stereo field.

Coaxial speaker and Component speakers

Coaxial speaker and Component speakers

#1- Coaxial Speakers

Coaxial speakers also are known as full-range speakers that have their drivers built as a single unit. The audio drivers for a coaxial speaker are normally a tweeter and a woofer. The woofer mostly covers the low and midrange frequencies while the tweeter covers the high frequencies.

Coaxial speakers can be further classified as 2-way, 3-way, 4-way and more regarding the way the above drivers have been brought together. A speaker with a tweeter and mid-range speaker is said to be a 2-way.

One with a woofer, mid-range driver and a tweeter is said to be a 3-way speaker. A 3-way speaker with an extra tweeter is said to be a 4-way speaker. Most of the full range speakers are 2-way and 3-way.

These types of speakers are the most popular types of speakers found most as 6.5-inch car speakers. The reason why they are popular is that they are easy to install and will take the position of the factory car speakers without any modifications been done on them or the car.

They can be quickly installed up front or at the rear without much wiring being done on them. Installing coaxial speakers only takes a few steps. It entails removing the door panels and if necessary the back dashboard panels which can be done at home with a few tools.

Since most of these coaxial speakers are found in the same dimension as the factory speakers, installing them will be done without damaging the interior of the car. Here is a quick video on how to install coaxial speakers.

#2- Component speakers

In trying to bring more life to the audio world, component speakers were invented. In short, the drivers were separated from the coaxial design and manufactured separately. This was to give the user more room to place these components in his or her best-customized way as possible.

By separating the components, specific frequencies can be channeled to individual components. In doing so, interference and muddiness are eliminated which are a common problem with coaxial units. The perfectness of a component unit will entirely depend on how it is set up.

A common set up of a component speaker will involve the tweeter being set in the direction of the listener’s ears, a woofer, and midrange drivers. A more advanced set up may involve the introduction of super tweeters and subwoofers. This will bring more frequency specialization and hence more clarity.

Installing this kind of speakers require advanced skills. There is a lot of wiring that needs to be done. The wiring is due to the introduction of a crossover responsible for channeling the specific frequencies to the individual components.

Why coaxial speakers

Why coaxial speakers

Now that you know something about these two types of speakers, let’s look at why coaxial speakers are still your best choice over component speakers in summary;

  • Quick and easy to install.
  • Offer single input terminal and one unit output drivers.
  • Can be mounted on the door and still give a great sound
  • Compatible with most factory systems installation points.
  • They are also less expensive.

We can’t dismiss the fact that component speakers are better in terms of stereo imaging and that they can still be good speakers to use when upgrading your factory speakers. We all know that we have to start from somewhere; coaxial speakers will be a good starter in my opinion.

Features to look for when looking for the best coaxial speakers

#1- Power handling

A highly rated speaker means it is powerful. The RMS, however, is what matters. The higher the RMS value, the higher the power it will need to be supplied to it continuously. Look for a coaxial speaker with higher RMS value.

#2- Sensitivity

This will matter a lot when choosing the best 6.5-inch car speakers. The higher the sensitivity, the lower the power requirement since sensitivity means the amount of 1 watt of power required to produce a particular amount of sound. A highly sensitive coaxial speaker of more than 90dB will work well with a lowly powered factory system.

#3- Size 

This might not be the case when dealing with coaxial speakers, but it is a caution to exercise. Always measure your factory car speakers before you make any purchase. Some coaxial speakers might have a unique shape design and might require more damaging modification done before installing them.

Wrapping up

After looking at all the important information, it has come to our time to give the final verdict of the best 6.5 coaxial speakers in our roundup.  Looking at the way these five speakers have brought out their features and relating them to the prices and what users are saying about them, we have chosen JVC CS-J620 Coaxial Speakers as our winner.

These are the features we keenly looked at; the cone, it is mica made with a hybrid surround that is fitted to steel frames which makes it durable and not susceptible to cracking due to excessive vibration. On power rating, we found it averagely good; a speaker running on a 30W RMS requires a modest amplifier which can be mostly found in car factory systems.

On impedance, frequency response and sensitivity, it falls within a range that most good speakers are supposed to be on which again leaves them good with the amplifier. Installation is another feature we looked at, and we love the way the installation of these speakers has been simplified. They have included shallow mounting design, screws, mounting tabs and grilles.

These are the features why we chose this particular speaker as our best 6.5 coaxial speakers. Do you agree with us? Have you ever installed any of the 6.5 coaxial speaker brands that we have reviewed above? If yes, how did it perform? Do you have another speaker brand in mind that we should include in our next review article?
