JBL Subwoofer Review

JBL Subwoofer Review

If you are an audio enthusiast or a music lover, you will know the value of a good quality speaker that provides clarity and richness at low-frequency sounds. However, it is not easy for the audio systems to produce flawless bass. The reason is that it is one of the most strenuous ranges of frequencies that the speakers need to reproduce. To get that powerful and perfect bass-heavy output, large speakers are needed that are expensive and convenient to install or carry. Just Like the JBL Flip. Speaking of which, if you would like to take a look at JBL Flip 4 vs Flip 5, All you need to do is tap right here. Random segue aside, I am sure you can glean some more context to your choice.

While it still makes sense to get a large speaker for your home, when it comes to cars, the automotive manufacturers are left with no other option but to go for an inexpensive speaker that is small to fit into the car stereo in the allotted space. This restricts the proper transmission of the low-frequency sounds in a piece of music, distorting the bass emphasized portions when the volume of the speaker is turned up.  

JBL Subwoofer and Its Role

Subwoofers have a major role to play in these situations. 

To boost up the low-frequency audio and give the bass focussed tracks a clean sound with a thumping effect without losing its originality, a good quality Subwoofer is needed. It acts as a key component to any kind of stereo system, be it for your home or the car. We will cover a detailed JBL subwoofer review that will include some of the best JBL subwoofers for cars and more.

Benefits of Getting a Subwoofer

To get more clarity on the role of a subwoofer in a sound system, here’s a breakdown of the various benefits of having a good subwoofer in your audio system: 

Improves Bass Response and Adds Clarity to the Sound:

The subwoofer enhances the bass response within a track. How? Most of the speakers when played at a higher volume start thinning out from 50 Hz and you start losing the clarity on certain notes. Especially the ones at lower frequencies.  A subwoofer will help augment the notes from 20Hz itself. Giving you complete depth and clarity on every note, giving you a better listening experience. It offers a solid pounding effect on the bass-forward tracks which the JBL subwoofer review speaks highly of, which some lower-end speakers may otherwise fail to produce or get cracked at high volume. 

No Distortion When Played on the Highest Volumes:

You might have experienced the songs getting distorted from the original piece in many speakers, especially the smaller ones when they are played on high volumes. This usually happens when the built-in woofers of your speakers fail to keep up the pace with the smaller drivers. The presence of a subwoofer can eliminate this issue and give you a smooth and flawless sound irrespective of how loud the volume goes. 

Offers Accuracy in the Notes Throughout the Frequency Spectrum:

One of the benefits of using a subwoofer is you can experience high quality and clear acoustics at every frequency, be it low range, mid or high range. You can get the exact feel the singer or the artist wants to bring into the song.  

Improves the Speaker Performance and Life by Balancing the Load:

Many smaller or full-range speakers when trying to reproduce frequencies in the lower spectrum get stressed and their performance is often compromised. The subwoofer takes the burden off these speakers, so they can produce sound at their comfortable frequency range without getting distorted. This also helps the speakers perform better as per their capabilities. 

Unveils Every Element in the Music:

The subwoofer gives you a heightened and immersive listening experience by differentiating every element in the track, be it the piano, the notes on a bass guitar, the vocals, or the beats of a drum. So you can thoroughly enjoy every essence of a track.

Unifies Well With the Speakers:

The subwoofers come in different qualities. The high-quality woofers are the ones that do not try to overpower the smaller speakers, rather, they work as an add-on to the speaker. This means that they allow the speakers to perform at their best while the subwoofers do their job of balancing the audio across the frequency spectrum. The result is clean deep lows, well-balanced low and high mids, and crisp and clear highs. 

Subwoofers in a Nutshell

In simple words, a subwoofer when used with your automobile’s audio system can increase the longevity of your car’s stereo speakers. It also supports the full-range speakers to perform better, to the most of their potential, and enhance the acoustics across all music genres be it Pop, Jazz, Rock, or the Classic numbers.  “Are JBL subs good?” A JBL subwoofer for a car can be a wonderful choice to upgrade the sound system of your car if you want to treat your ears with your favorite tunes on the go. All of this with the perfect balance of the elements and a bass-emphasized surround sound. 

If you are thinking about where you can place the woofer in your car, as there is limited space, then you need not worry. Concerning the JBL subwoofer review, these audio enhancers are extremely versatile and can be placed anywhere. If you do not have space on the front side of the car or don’t fit under your car seat, you can place it in the trunk. You will be able to experience the same quality of the surround sound effects as though it is placed under your seat. This means that you can experience a 360-degree bass sound in your car. 

What Are Some Major Factors to Consider Before Buying a Subwoofer?

Among some top companies known for offering sound systems, JBL is a well-reputed name in the market that provides exceptional and innovative audio accessories. We are going to go in-depth about the JBL subwoofer for cars that are worth picking up in the latter part of this article after covering a few more things you should know about the subwoofers that will help you shop yours.

Now that you know the role of a subwoofer in your audio system, let’s move on to see what are the various things that you need to consider buying for your car. On the other hand, if you are looking for a good system for your home, take a look at our JBL bar 5.1 soundbar review.

There are many brands offering subwoofers that are used as an extension of your car’s audio system, and it will be confusing to come down to one particular product. To help you narrow down your search and get the exact product that will meet your expectations, here’s a list of some critical parameters that you need to take into account when buying a subwoofer: 

Size of the Sub:

This is an important aspect to consider, and people often face difficulty in determining what size to get, or what size would give the best output. Do remember that the bigger the woofer, the better and powerful is the bass. With that being said, you need to first consider the space in your car under the seat or in the trunk and decide where your sub will go. 

If you think you have a decent amount of space to accommodate a bigger sub and want loud and rich lows, then go for a bigger one. Don’t forget to take the measurements of the space where you are planning to install your subwoofer. With that said, if you do not have a lot of space in your car, you can go for a compact one but make sure that they are connected to the proper power output and well enclosed for effective and equally powerful performance as the big ones. 

Enclosure Of Subwoofers:

The subwoofer enclosure is nothing but the box that holds the sub. Different types of enclosures offer different audio output and depending on what kind of music you like you need to choose them. There are four types of enclosures- 

Sealed enclosure

This type of enclosure is an airtight box where your sub is mounted. It is perfect for a well-balanced and accurate bass effect in music. You will get a flat response, where the lows are not too thumping nor plain. This type of enclosure is recommended for music that uses all frequencies, so the output is perfect. Do remember that if you choose this type of sub, then the power output has to be more for best performance. 

Ported Enclosure

This is used if you need a louder and more intense bass effect. The output from this type of sub is more than that of sealed and is suitable for music genres like rap, rock, or heavy metal music for a powerful baseline. 

Bandpass Boxes

These are a type of ported enclosures that are made for extra thumping effect. They may work well in a large room or an open space, and not every subwoofer performs well with bandpass boxes. It may not also be a fit into every type of music because of the sound that dominates everything else. Therefore, this type of enclosure is only suitable for rap, heavy metal music, or hard rock. 

Free Air Subwoofers

In this, the subwoofer is fitted to the wall on the rear deck or installed in the trunk of the car. Since these subs are not built with a proper enclosure, the trunk acts as the enclosure and contributes to the noise cancellation features, enabling the speaker to deliver sound. Free air subwoofers are specially designed to work in a free air setup. They are pretty easy to install when compared with the enclosed subs but never yield as powerful of an effect as those covered or even ones that are enclosed. 

Power Output:

If you are looking out for a good subwoofer, you need to keep an eye on the RMS power rating. The RMP power rating measures how much power is used by a subwoofer realistically or a speaker can handle.  This rating is a measurement that calculates the speaker’s capacity to the amplifier’s power output. Simply put together, before purchasing the subwoofer, just make sure that the sub and the amplifier’s power output (rating) match with your car speakers’ capacity. Also, a higher power RMS value means more powerful bass.


Sensitivity rating is also an important factor to look for when buying a sub. The higher the sensitivity rating, the more powerful and louder the sound the subwoofer can go and the less power the sub will require delivering high volumes. Sensitivity is the amount of power the woofer requires to produce a specific volume. 


Don’t forget to make a note of the impedance of the subwoofer you are purchasing. Impedance or the electrical resistance is measured in ‘ohms’. Subwoofers with low impedance produce sounds that are louder than the ones that have higher impedance. This means that a sub with a 2-ohm impedance will offer you a louder sound than the one that has 4-ohm resistance. You will have to go for a subwoofer, whose impedance goes hand in hand with the car speaker and amplifier’s power.

Frequency Range:

This is important because based on the frequency of the subwoofer, you will know how low a sound it can play. The lower the subwoofer plays, the better and crisp base it can yield. Go for a subwoofer based on the type of music you prefer, or you are going to play in your car sound system. For example, if the majority of the songs you play are bass emphasized and at low frequency, then you need to look for one that can handle low range well. The frequency range of a subwoofer also depends on various factors like the enclosure, the material of the box the sub is fitted on, etc. 

Now when you go to purchase a subwoofer, hope the above parameters help you get the right kind of product for your car audio system that will last longer and give a good audio performance.


The bottom line is if you want to add that extra punch to your car’s audio output or improve the sound quality of the audio system, JBL has got it covered for you. If you want a more portable option, take a look at the JBL Flip 3 speaker review.

JBL subwoofers for cars come in a wide range of product lines with different power handling capacities, sizes, and sensitivity under different price tags. No matter what type of music you love to listen to, a good-quality subwoofer can make your listening experience more enjoyable by upgrading the ordinary audio system of your car into a powerful bass-emphasized surround sound. One important thing to remember is to make a note of the space you are planning to keep the sub, and then purchase yours accordingly. This is an important factor that most people seem to forget, Something to take away from the JBL subwoofer review.
