What You Should Consider When Buying the Best Shallow Mount Subwoofer
From the above review, it’s evident that each shallow mount automotive subwoofer comes with several desirable features and a number of shortcomings. Thus, these subwoofers are not made equal. It’ll help to learn the factors to consider when making a purchase. Here’re the most important factors you should consider before spending your money on a shallow mount sub:
You’ve most likely landed on this page because you need a subwoofer that can fit in a tight space, probably beneath the seat or in the door panel. In this case, a shallow mount subwoofer with the least mounting depth will be your best bet. A subwoofer with the least mounting depth will allow you to fit it in an extremely tight space or enclosure. A narrow mounting depth doesn’t require a lot of air space such that you can fit the subwoofer in a compact enclosure to save on space. Moreover, a narrower mounting depth allows for tighter and more accurate bass.
Type of Enclosure
Subwoofer enclosures are either ported or sealed. Some shallow mount subs come with an enclosure while others don’t have one. Also, some of these subwoofers are designed to only support either a ported or sealed enclosure, while others can work with both enclosures. The determining factor should be the kind of bass you want. If you need accurate and tight bass, then you should go for a sub that comes with a sealed enclosure or one that supports a sealed enclosure. On the other hand, if you need louder and more booming bass, then you’d rather go with a sub that supports the use of a ported enclosure. You can also install a subwoofer without using an enclosure, especially when mounting it in the door panel.
Number of Voice Coils
Some subwoofers come with a single voice coil while others feature a dual voice coil. While the number of voice coils doesn’t determine the overall performance of a subwoofer, it determines the flexibility of installation. This is especially important when wiring multiple subwoofers. When wiring multiple subwoofers with a single voice coil, you can only wire them in parallel. On the other hand, when wiring multiple subwoofers with a dual voice coil, you can wire them either in series or parallel. Thus, with a dual voice coil, you’ll enjoy multiple wiring options.
The impedance rating of a subwoofer determines the amount of power it’ll draw from the amplifier. Basically, impedance is used in measuring the resistance of a subwoofer to current. The lower the impedance rating of a subwoofer, the higher the resistance and the more power-hungry it is. For instance, a subwoofer with an impedance rating of 2 ohms will demand more power than a 4-ohm subwoofer. If you have a very powerful amplifier, then you can opt for a subwoofer that has a lower impedance rating. However, if you’re dealing with a weak amplifier, then you should go for a subwoofer with a higher impedance rating as it won’t require much power.
The power handling of a shallow mount car subwoofer also matters. Power handling comes in terms of both peak power and RMS power. The peak power rating is the maximum amount of power surge that the subwoofer can sustain. On the other hand, RMS power is the continuous amount of power that the subwoofer can handle. In this case, RMS power is a more important consideration to make than peak power. The higher the RMS power rating, the harder you can push the subwoofer without distortion. On a similar note, a higher RMS power rating demands a more powerful amplifier. Also, avoid overpowering the subwoofer beyond its power handling capability to avoid distortion or even permanent damage.
The frequency range of a subwoofer determines how low it can play. If the subwoofer has a wide frequency range, it can hit a wider range of lows than a subwoofer with a narrow frequency range. However, if you need extremely deep bass, go for a subwoofer that can hit the lowest lows.
Yet another important consideration to make when choosing the best shallow mount automotive subwoofer is venting. A subwoofer does a lot of heavy work to move large volumes of air when reproducing low frequencies. Thus, its components, especially the voice coil, are prone to overheating when driving it hard for a prolonged period. As such, you should ensure the subwoofer you choose has proper venting. The subwoofer housing should be properly vented to allow for free air circulation throughout the interior components. As air circulates within the subwoofer, it cools the voice coil and other components to prevent them from burning out.
Durability of the Subwoofer Materials
The overall durability of the subwoofer matters. After all, you don’t have money to waste buying a new subwoofer now and then. Thus, consider a subwoofer whose components are made of durable materials. For instance, ensure the cone is made of a lightweight but rigid material for easier cone movement with reduced distortion. Also, ensure the surround is made of a material that doesn’t tear and wear easily. The voice coil should be made of a high-temperature material to sustain prolonged usage. Another important component to consider is the subwoofer housing. The housing should be strong and stable enough to keep the components in place and to protect them from damage.
Ease of Installation
As a busy person, you obviously want a subwoofer that you can install easily and quickly. A subwoofer that is easy to mount without having to tear up anything would be your best bet. The best subwoofer is the one whose installation process is as easy as plug and play. Ensure the subwoofer you choose comes with mounting hardware for easier installation. Also, the subwoofer should have terminals that make it easier to attach the speaker cables without soldering.
A car music system can only sound complete with decent bass. However, some car spaces are limited. As you have seen in this review and buying guide, the shallow mount kind of subwoofers are a great option for adding bass in cars with limited space. Since we’ve reviewed the best shallow mount subwoofer from the dozens available in the market, you’ll find it easier to choose a subwoofer that will give you the best value for your money.
