The very first subwoofer was developed in the 1960s to amplify the bass responses and to intensify the peak power of home stereo systems. From there, they developed in; shape, size, and quality, then became almost universally famous in the 2000s when they were introduced in concert venues and nightclubs as sound reinforcement systems.

Things To Consider When Purchasing a Proper Suited Shallow Mount Subwoofer

When it comes down to purchasing the best shallow mount subwoofer, you need to be able to determine the one that checks out in all of your subwoofer feature qualifications. To be in a position to do that, you need to consider the factors below:


This feature is as important as any other since it determines the quality of sound a shallow mount subwoofer produces hence impacting its performance. Enclosed subwoofers are pre-mounted in enclosures that are designed specifically for containing them. Amplifiers are purchased separately since they are not inclusive of enclosed subs. While bandpass and ported enclosures permit high volume levels, a subwoofer suited for a sealed box will generate deeper bass. Even though enclosed subwoofers are scarce in markets, they are a great and simple solution to your sound system upgrade.


Component subwoofers have multiple parts that function together to customize sound systems. It is up to you to decide the kind of amplifier and enclosure you need. Despite these subwoofers being assigned to meet your audiophilic needs, a bit of technicality is involved for it to function. On the other hand, non-component subwoofers have everything you need in a single enclosure. It is an ideal type for people looking to avoid complications that may occur while installing this type of subwoofers.


In the general sense, the shallow mount subwoofer should be able to:

  • Protect factory speakers: Having too much could damage the factory speakers in your car since they are not designed to withstand large vibration levels. Subwoofers are designed to strengthen lower frequencies within your car. Not handle massive quantities of bass. An OEM speaker, for example, may even crack and tear considering they are made of cheaper materials
  • Capacitate smooth sound output: Subwoofers should be able to control the direction of lower sounding frequencies in your car. They do this through powerfully channeling bass notes with a cleaner sound, drawing your speakers to focus on higher sound ranges
  • Boost audio system’s bass: A powerful subwoofer would enhance your music tremendously compared to your car’s original speakers. They present deep bass undertones that standard speakers can’t put out. Shallow mounted subs, therefore, have more impact and power

Voice Coils

While dual-voice calls allow flexibility when increasing additional sound output, single-voice coils suit a simple and quick audio system upgrade. If you want to be hands-on with pursuing the best sounding stereo, then you should opt for dual-voice coils.


Powered subwoofers have an amplifier built into their enclosure, making them the perfect fit for small spaces. Subwoofers differ from each other in watt rating, which is used to determine their power output. Those that operate on high ratings for a prolonged period overheat and eventually fail. It is important to refer to the root mean square to know how much power handling your sub can do.


Subwoofers used in vehicles often vary from 8 to 15 inches in size. Large subs have louder basses, but this is not always the case. Other factors that are subjected to the size of your sub are RMS and peak power. Shallow mount subwoofers are small in size, and this makes them suitable for compact placements. A larger speaker would be harder to mount in your car.

Vehicle Specification 

Subwoofers specifically used for cars are sizable enough to fit in multiple places in your car, SUV or truck. If you own a small car or wish to place them away from your line of sight, this will help you buy the perfect subwoofer. They usually come pre-mounted in enclosures in your car and are designed to match the car’s interior. However, in this case, you will be unable to control the intensity of the sub’s sound.

Sensitivity Rating

Sensitivity values and power ratings are used to determine how powerful the sound coming from your subwoofer is. Highly sensitive subs have the ability to produce the same level of limited sound power compared to subwoofers with low sensitivity.

Frequency Range

Subwoofers are bound to the frequency range that they can gain. Those with smaller lower limits produce deep, lower frequencies, while those with higher limits can’t go as low in frequency. If you want a really deep bass sound experience, then going for subs with the lowest frequency limits is what you should do.


Shallow mount subwoofers come in different: specifications, brands, and sizes, which renders each one of them unique. This might create conflict when trying to pick just one out of the endless pool of variety and declare it the best. However, with the attributes outlined by this article, it will be effortless to choose one that might meet all your sub expectations. With that said, it’s time to place an order for your new shallow mount subwoofer. Good luck!
