Product highlights

For many years, no product has passed my design, features, and performance tests. Surprisingly, the DS18 Pro is the first device that can accomplish everything and is the complete version of my collection.

This product comes with a cutting-edge design with top-notch materials to stay sustainable over time. It also completes a more excellent output sound quality.

I used small vibrations to test the product’s durability with the output sound.

Incredibly, the device still maintains the song’s melody and does not have the distortion like in conventional products.

To test the sound quality, I played 12 different music streams simultaneously. As a result, it can both catch up to the tune quickly and accurately.

With deep classical songs, the bass comes out incredibly smooth and real. Meanwhile, high-pitched lyrical vocals can’t make this super sound product difficult.

The device’s sound fill is equally excellent. It can fill your car space with music in just a few minutes. Accordingly, each of your experiences will be more comfortable and meaningful.

Dust can seriously affect sound quality, so if you don’t clean it regularly, you will have to pay an extra fee to replace the car speakers.

Is there any suitable solution if you are busy and do not have time to clean? DS18 Pro is an ideal suggestion for this case. This version features a smart dust cover to protect the voice coil and provide optimal sound.

Noise levels with this product are a challenge. The noise level increases when playing music at a high volume and can seriously affect your sound output.

  • Large output power
  • Quickly fill the sound
  • Effective dust resistance

With many of the above advantages, I am surprised by its low price, which is suitable for most low-middle-income people. Specifically, to to buy this smart speaker, I only needed to save 1 month’s pocket money.

As for the downside, I’m pretty concerned about the material quality of this version. Maintaining a long life for the speaker’s operation is not good. Therefore, you must take great care to keep it regularly in the ideal condition.

These 6 5 speakers are admirably resistant to heat and sunlight. This advantage helps the speaker avoid ambient conditions’ influence and operate stably for a long time.

Its water resistance is equally remarkable. During a trip, my son accidentally splashed juice on the speaker. Fortunately, it does not affect the sound and operation of the speaker.

The thing that bothers me the most about this product is the price because it is pretty high compared to my ability to pay. However, what I got in return was worth it.

Of course, the low price makes it easy for most general users to afford. So what’s so special about this cheap product? How much power does it provide?

Unique, creative, and attractive design is the first advantage you can quickly see in this product. It has an eye-catching yellow CD PP speaker cone texture with noticeable stiffness but does not add to the product’s weight.

I am interested in its color version because it is fancy and has a very different point from the products I reviewed before.

About the sound quality, I was pretty surprised by its performance. The music I record from the speaker is deep, multi-dimensional, soft, and extremely pleasant. It doesn’t include the shrill noises that increase the volume to the top.

Experimenting with annoying music like rock, this speaker is still extremely friendly to give users the best entertainment experience.

The frequency response is also the finishing touch of this product. With a particular magnet structure, the Pyle PLG64 can respond to a frequency of 60 Hz – 20 kHz to provide loud, clear, and distortion-free sound.

I do not overestimate the treble pronunciation of this product. It can’t get too high to capture my favorite bolero tunes.

Choosing and using this product saves me a lot of related costs. I could quickly bring this speaker home with only a fraction of a month’s salary.

Accordingly, it clearly shows us the excellent bass quality. But it’s a pity that it can’t respond well to the frequency range of music with treble notes.

This speaker has a rather monotonous design and does not include a guard like other collections’ products. However, that cannot hinder the performance of the Skar Audio TX65. No agent will defeat this powerful version.

Buying Guides

Best 6.5 Speakers Without Amp

There will be many models from various brands for you to consider. You need to sort out the pros and cons of each and find the version that best suits your use.

You should pay attention to some critical factors, such as speaker type, power handling, impedance, sensitivity, material, and price.

Speaker Type

Car speakers can be classified into 3 main categories, full range, component, and coaxial speakers. Here is an overview of each speaker’s characteristics.

  • Full range speaker

It is the most popular type to provide an easy installation solution for all magnetic cars. This version contains all the necessary audio drivers to enable users’ most immersive entertainment experience.

  • Component loudspeaker

The basic construction of the component loudspeaker is similar to that of a range loudspeaker. But it comes with an extra frequency unit that separates the bass, mids, and high-pitched sound frequencies.

The audio performance of these speakers is also better than the range speakers, but they are also quite expensive.

And the Pyle PLG64 is a prime example of the best component speakers.

  • Coaxial speaker

It is similar to a range speaker but has a separate tweeter to improve quality.

Energy treatment

The best 6.5 speakers must have a minimum peak power level to produce the best sound. If you don’t provide enough, the sound can be ruined, or you won’t hear any detail in the track.

When buying 6.5 speakers with good bass, you need to consider the speaker’s power handling capabilities. It is measured in watt units, indicating the maximum peak power you can provide for the device’s regular operation.

RMS is also an important indicator that you should pay attention to. As a rule, an RMS of less than 60 watts is safest for low-power devices.


The lower the impedance, the better. But, if the impedance is too low, it will put a lot of pressure on the amplifier.

From personal experience, I think that choosing component speakers with an impedance of 4 ohms is the best.

It is suitable for making the speaker work most efficiently and accurately.

Between 2 Ohm Vs 4 Ohm Car Speakers, 4 ohms is still more ideal for generating stable current and being well compatible with amplifiers.


Speaker sensitivity will have a lot to do with the dB parameter.

For excellent sound quality, it’s best to look for versions with sensitivity ratings of 80dB or higher.

If you own a device with too high or too low sensitivity, it will reduce the quality of the effect. Or it can even seriously affect your hearing.


Material is an essential factor affecting the overall sound quality and is closely related to the speaker’s durability. With the Woofer part, the most popular material today is polypropylene, which is both strong and light.

When the hat is in form, it won’t wobble when tuned to the highest volume. It allows mid-level stability of the bass and does not distort them.

In the Tweeter part, it is made of soft materials such as textiles and silk. I highly recommend these materials because they make the sound warmer and lighter.


When choosing the best 6.5 speakers for bass, you need to keep their installation in mind. Above all, you should have equipment that is easy to install, flexible, and comes with detailed instructions.

If you feel uncomfortable with the installation, it is smart to seek the help of technicians in an auto repair shop.


The cost of each 6.5 speaker is different based on the sizes of the car speakers, impedance, sensitivity, and audio performance.

You need to rethink your intended use to buy the right quality product at an affordable price. Remember to choose the version whose cost fits your budget.


Upgrading car speakers without an amp is entirely possible. With the best 6.5 speakers without amplifier collection above, you will easily accomplish what you want for the high-quality sound.

For me, the DS18 PRO-X6.4BM is the product that left the most impression. It has a complete finish with a quality sound.

Meanwhile, the Kenwood KFC-1666S also offers outstanding durability. It has particular strength in the ability to install and repair, which will significantly help you during operation.
