Buying Guide: The Ultimate for Buying the Best Shallow Mount Subwoofer

Shallow mount subs sound great, and they are awesome as far as saving space is concerned. While they are intended to have the same functionality as standard subwoofers, the two differ in terms of configuration and performance. With that in mind, let’s see how they compare and contrast before you put your money on the line.

1. The Size Factor

Size is an important consideration that defines a shallow mount subwoofer. They come in different sizes that range from 8-15 inches. Let’s see what each size option has to offer;

  • 8-inch subwoofers: They are the smallest in the market, and they are ideal for light and soft bass. You can go for this size if you just want to compliment the bass of your audio system. In addition, these subs are quite responsive; hence they can keep up with fast-playing music.
  • 10-inch subwoofers: 10-inch subwoofers are the perfect examples of well-rounded subs that are safe and produce enough bass for any music track, whether fast or slow-paced.
  • 12-inch subwoofers: 12-inch subwoofers are popular with music enthusiasts with a bigger bass appetite. They work well with a lot of frequencies and handle different types of music with perfection. They are, however, not appropriate for fast-paced music.
  • 15-inch subwoofers: Due to their big size, the 15-inch subwoofers work perfectly in trucks and other large cars. They offer the most powerful and deepest bass out there. They are, however, less responsive when it comes to fast-playing music.

2. Key Specifications

Apart from the size consideration, you may want to pay attention to the following features to get the best from the unit;

  • The power rating: You will need to pay attention to both the peak power and the RMS power rating. While both are important, you may want to focus more on the RMS rating as it is the amount of power the sub can take continuously take without running the risk of blowing up. This aspect is a good indicator of how powerful the unit is.
  • Sensitivity: A sub’s sensitivity is measured by how loud the sub is, which is determined by the amount of power required to produce a certain volume level. A higher sensitivity sub will provide you with more power and volume if you are using a low-powered amp. If you are using a good powered amp, then a sub with low sensitivity will still serve you perfectly.
  • Impedance: This is the measure of how a sub is resistant to an electrical current. It determines how easily the sub translates the signal from an amplifier into sound. Lower impedance produces better sound quality when compared to higher impedance. This is because a less resisted system will experience less distortion hence transmitting a quality signal. It is important to match the impedance of the sub to that of the amplifier so to avoid damage.
  • Number of voice coils: You can either choose a single or a dual voice coil. A dual voice coil can be wired several times to take up more power from your amplifier. This flexibility also means that you don’t need to get an extra subwoofer when you upgrade your head unit.

3. Woofer Surround

There are a couple of materials that can be used on the subwoofer’s surround, the best one being rubber. This is because it reduces resonant vibrations leading to the production of quality sound. Some surrounds are made of plastic which has some negative implications on sound quality and longevity of the sub.

When it comes to the cone, complex materials such as polypropylene are used as they provide both durability and flexibility. The advanced system may use a combination of glass and woven fibers to strike a balance between the two aspects.

4. Best Spots to Mount your Subwoofer

Depending on the space available in your car we recommend the following spots as the best placement spots for the best results;

  • Under-seat: This is a perfect spot for small-sized subs with small enclosures. As such, if you have an 8 or 10 inches sub and showing it off is not much of a priority, then you can simply get it under the seat.
  • Trunk: You can mount your sub on the trunk with its enclosure, depending on how big your trunk is.  Mounting your sub on the trunk will serve as a big advantage, as you don’t need a big enclosure for it to perform well.

Final Verdict

The size of your car or the space available should no longer limit you from enjoying big bass sounds. With these shallow-mount subwoofers, you should be able to get those rich beats in your car. Shallow mount subwoofers are compact, easy to install, and serve as a practical solution to any audio enthusiast who wants to transform the audio system within no time.

These shallow mount subs come with a range of features, and they fit different budget needs. It is difficult to choose one model as the best, but we can assure you that all units will satisfy you on all fronts. But generally, it will come down to your specific needs and pairing the sub with the right components.
