Types of Competition Subwoofers

·      Component Subwoofer

This type of subwoofer is the speaker itself; it does not come with an external amplifier or any enclosures. For component subwoofers, the sound quality largely depends on the type of amp you use. So this is ideal for someone who wants to personalize and build the system from scratch.

·      Enclosed Subwoofer

The enclosed subwoofer is the one that comes with an enclosure box. Although you will still need to get an external amplifier, they work pretty amazingly in enhancing the quality of the bass.

·      Powered Subwoofer

A powered subwoofer is a compact speaker system that comes with the amplifier. This type of subwoofer produces good, deep bass, and its convenient size makes it so simple for installation.

·      SPL And SQ

SPL (Sound Pressure Levels) and SQ (Sound Quality) is another type of subwoofer that gives out a different quality of sound, which in the end depends on your preference.

SQ focuses on clarity and accuracy, where you can hear every frequency clearly, whereas SPL audio system is all about loudness.

Competition Subwoofers Buyer’s Guide

Deciding on the right and the best competition subwoofer for your car can become a difficult task if you have no clue what to look for. Therefore, to help you make your search easier, here are a few things to consider when buying a competition subwoofer.

Buyer’s Guide

·      Power

You should check that a competition subwoofer has high power because, with a higher power, you are more likely to get a louder, deeper, and cleaner bass. Therefore, do check the RMS power handling for better performance of the subwoofer.

·      SPL

A good professional speaker is measured in SPL (Sound Pressure Levels). So it is suggested to look for a competition subwoofer with SPL below 80db to be safe. Because there is a chance of possible ear damage if it goes above 85db.

·      Bass

It is essential to check the quality of bass a competition subwoofer has. Check the ranges of frequency, since it is crucial to have the right frequency to receive the right kind of bass. And to make sure that you have the right frequency, it is preferable if the frequency ranges between 20 Hz to 200 Hz.

Although, with a good professional audio system, you can typically use a subwoofer that comes with 100 Hz or under.

·      Voice Coils

The competition subwoofer comes with two types of voice coils. A single voice coil and a dual voice coil, and both types of voice coil works amazingly, giving excellent quality of bass sound.

However, a single voice coil is more comfortable to install, and is cheaper, hence it is ideal for someone new to competition subwoofer. But if you want to go all out, then dual voice coil should do you good. Although they are a little more challenging to install, they provide a high-quality sound just in general. So, depending on your requirements, you may make your choice.

·      Size

Irrespective of the size of the subwoofers, the good ones will always have a better overall performance. There are massive subwoofers that give the best sounding bass, and likewise, there are compact-sized subwoofers with strong bass.

Therefore, the size of the subwoofer does not affect their performance. However, when it comes to its set up or fit of the car, you cannot overlook the size of the subwoofer. You will need to consider the space you have in your vehicle and accordingly buy the subwoofer that best fits it.

·      Enclosure

When shopping for a subwoofer, check if they come with an enclosure box, because not all subwoofers come with enclosures. Also, there are different types of enclosures, and they perform differently, too. The quality of the sound is mostly dependent on the type of enclosure you mount them on.

The subwoofer that comes with a sealed enclosure gives you deep and intense bass, while a subwoofer with an open enclosure produces a precise and tight bass. And the one with a ported enclosure gives a louder bass than compared with the first two, which makes it perfect for those who love volume over accuracy.

Frequently Asked Questions Regarding Competition Subwoofer

What is a Competition Subwoofer?

A competition subwoofer is a loudspeaker that produces a low-frequency sound called bass. They play an essential part in enhancing the sound quality of your music. The competition subwoofer is praised by many over the standard subwoofer because they offer better benefits. They not only provide powerful sound but also have a high output enabling them to produce the loudest sound and easily beat the other competitors.

A competition subwoofer is a go-to for anyone who loves intense music sessions. The depth this competition subwoofer offers will no doubt surprise everyone around you.

What subwoofer has the deepest bass?

The American Bass Elite-1244 is one of the deepest bass producing subwoofers in the market. The catch of this subwoofer is that it has the power equivalent to that of XFL woofer but at a more affordable price range than the XFL woofer.

With its high temperature, four layers of voice coils, and a whopping 2400 watts peak power handling, this subwoofer is no doubt one of the best powerful subwoofers you can find. This subwoofer hits the low smoothly and excellently and produces an incredible quality of sound.

Are 15-inch subwoofers louder than 12?

The frame and the size may, to some extent, impact the subwoofer’s overall performance. The 12-inch subwoofer will have more space for more air to move than compared to the 12 inches. But also, this does not imply that a 15-inch subwoofer will go deeper than 12-inch ones.

Because a 12-inch subwoofer in the right enclosure is capable of going deeper than the 15-inch subwoofer, this goes to show that the size alone does not determine the loudness of the subwoofer. You need to look into the details such as the response frequencies, passive or active, if their enclosures are sealed or ported, etc.

Should I get a 10 inch or 12-inch subwoofer?

If a 10 inch and a 12-inch subwoofer have the same specification or the same wattage, then the 12-inch subwoofer, since it is bigger, will move more air than the 10 inches, meaning that it can go louder. But apart from this, there are so many more factors you should consider to decide between the two, factors such as enclosure type, power, a specific vehicle, etc.

So, to choose which subwoofer to get purely depends on your personal preference. But a point to note is that smaller subwoofer tends to be slightly more controlled when it comes to tight bass. But again, every opinion differs depending on the type of bass you prefer.

Is it better to have one or two subwoofers?

In general, it is always better to have more subwoofers because it will significantly yield smoother and better sound. Thus, it is definitely better to have two subwoofers as their combined surface area produces more pressure; this results in a deeper and cleaner sound.
