Factors To Consider While Choosing The Best 8 Inch Subwoofer 2020

Powerful and undistorted bass in the car is the desire of every car owner. That’s why the market is flooded with audio equipment. Even in the 8-inch subwoofer category, you get loads of options available.

However, to choose the most suitable option for your car, you need to focus on and compare several distinguished parameters. To sort your every trouble, here is a list of some essential factors that you must look for while purchasing the best 8-inch subwoofer. –

1. Power

If you desire that loud and clear low-frequency sound, then power is definitely the first factor that you should consider.

Whenever you observe a subwoofer, always notice the RMS (root mean square) power ratings. RMS power means the continued power handling that your subwoofer is going to work upon. Make sure that the subwoofer is able to handle your amp’s power.

The peak power is the level which the device can manage for a short period and would fail down if it is made to operate at that range. RMS is the power that the woofer can consistently manage.

2. Enclosure Type

The next important feature of any subwoofer is the type of enclosure you get with it. Surprisingly, the enclosure a sub is mounted in can dramatically affect the output sound of the subwoofer.

There are various types of enclosures available for the subwoofers. However, the most suitable enclosures for an 8-inch subwoofer are the sealed box ones. They help in producing deep and tight bass.

Furthermore, ported enclosures or bandpass enclosures allow higher volume levels. Thus, if you prefer loud music over a tight one, you can go for these sorts of enclosures.

3. Sensitivity

Sensitivity is an important aspect that helps in producing loud sound and higher-quality output.

In the simplest words, the sensitivity of a subwoofer means how much volume you get from the device when you give a certain amount of power to it. A subwoofer with a higher sensitivity rating will produce the same amount of sound in lower power than a lower sensitivity device.

In general, a sensitivity range above 88 dB is considered above average and a good range. Anything below 84 dB is considered to be poor. For a good quality sound system, the sensitivity of 92 dB or higher is supposed to be the best.

4. Frequency Range

As you know that bass means low-frequency sounds, then a device that can produce the lowest sounds would be undoubtedly the best.

If you are looking for a high-quality bass sound, then it is advisable to go for a low-frequency range sound device.

A subwoofer with a smaller lower limit means it will produce deeper lower frequencies, A lower frequency range between 20-30 Hz is considered to be extremely powerful and deep.

5. Number Of Voice Coils

The next factor is the number of coils used in the sound system.

If you are looking for an instant update in your car’s sound system, then single voice coil subwoofers are a good choice. However, if you want an unprecedented sound in your car, then investing in the dual coil subwoofers is highly recommended.

They give you lots of flexibility in wiring the sound systems. Dual Voice Coil (DVC) subwoofers use two separate connection coils that are mounted on one cylinder and later connected to a single cone.

Thus, if you enjoy powerful and personalized stereo sound, then you should definitely consider going for a DVC subwoofer.

6. Size

Now comes the most asked query, i.e., the size of a subwoofer. What is the best size of the subwoofer for your car depends solely on your car’s space and your choice of music.

If you don’t have any space problem in your car then big or even the biggest subs are the best for you. However, if you want a maximum sound in a limited space, then you can choose a smaller subfactor.

Most of us believe that big subs produce the loudest bass. However, this is not the case most of the time. Various other factors such as the enclosure, sensitivity, or power handling affect the performance of the subwoofer.

Many times, a properly powered sub in the right enclosure can produce a loud sound or even a sound better than the big subs.

So, you don’t have to worry that a small sub will produce less bass and after considering the space in your car, you can conveniently choose the size of a sub.

7. Impedance

The last determining factor is the impedance offered by the system. Impedance affects the flow of current in the system and thus affects the final performance.

Subwoofers are available in a range of 1 to 8-ohm impedance ratings. Depending upon your sub’s impedance level, you can choose your amplifier. Make sure that your speakers and the rest of the sound system have the same impedance so that you get the best possible sound as a result.

Along with these factors, you should also look for the warranty/guarantee and the replace/refund policy of the manufacturer. Many times, you are not satisfied with the product or a sub might not fit into your car the way you desire.

In such cases, warranty or refund policies become really helpful.

Lastly, you should also consider the price and your budget before buying subwoofers. If you are planning to get a new car after a while or upgrade the factory system first, then choosing a medium budget subwoofer is highly recommended.

  1. How Many Subwoofers Do I Need To Get The Best Sound?

    It solely depends upon your choice and preference for music. If you like a lot of hip hop, dance, or techno music stuff, you might consider getting two subs for your car. However, there is no such urgency as a single sub is capable enough to make you give the best vibes and powerful boomy bass.

  2. Many Car Owners Fill The Enclosure With Fiber. What’s That For?

    Polyester fiber decreases the resonance in the system and hence gives you a clean and louder sound. If you want an even better performance from your subwoofer, you can fill the enclosure with polyester fiber material.

  3. Even After Adding A Subwoofer, The System Is Not Giving A Great Sound. What Should I Do?

    The best thing you can do even if attaching a subwoofer isn’t giving the desired results is upgrading the factory sound system. Your car’s inbuilt sound system can give you limited results and might need to upgrade with time. Believe us, it will make huge differences and give you the desired thump and thrum.

  4. What Is Better – A Mono Amplifier Or A Multi-channel Amplifier To Power The Subwoofers?

    Mono amplifiers belong to Class-D amplifiers and are definitely the best choice for powering subs. They also have a higher power-to-hear ratio and greater efficiency. Hence, they are better than multichannel ones.
