What Is A Subwoofer?
A subwoofer is a 18-inch speaker that can produce bass frequencies. The typical range is found between 125Hz to 20Hz in these speakers. Therefore, the speakers produce a realistic sound and are a great improvement for your home theater or work as an add-on to your customized sound system. In case you want to install the subwoofer yourself without a help of a professional, you can watch this video on how to install a subwoofer for your car:
How Does Subwoofer Work?
Subwoofers are electromagnetically driven, generally. They have a stiff cone run by a single voice coil centered in a magnetic field. With the single voice coil attached to the back of the speaker, it moves when current flows through it; therefore, pushing and pulling on the driver cone which moves in and out like a piston, creating waves as it's in motion.
Do I Really Need A Subwoofer?
You think a bookshelf speaker will do just fine, since you don’t need a home theater or a professional sound setup since you don’t do music, or watch that much movies. And that’s true, in some cases. But, a subwoofer will do more than just deliver low-frequencies sound, it also reduces the work for your sound system; therefore, improving your sound system.
The subwoofer covers a lot of the instrumental sounds to produce a song such as the kick drum, bass guitar, and the pipe organ (you’ll miss out on the best way to enjoy the music piece using these instruments). Without the subwoofer, these sounds won’t be properly reproduced with a regular single speaker. Even with action movies, the explosions are best reproduced by a subwoofer.
However, if you’re only looking for a light speaker and not ready to tear down some walls with extreme but excellent bass, then it may not be for you. The smaller size may be suitable for your choice since the 18 inch version subwoofer is made for loud, thumping bass.
What Should I Consider When Finding The Best 18 Subwoofer?
Although there isn’t much variety between one 18 inch subwoofer to another, you should consider carefully some of the factors that made up the subwoofer to choose the most suitable one for your needs. This will avoid the problem of picking the wrong one for your sound system or setup. These factors can range widely from power source, sound delivering, shape, voice coil, components made up of the subwoofer to your taste of music as well. So read carefully to know about which factors will be vital in choosing a best subwoofer.
Most of the time, you will find the information about the peak power and constant power rate in the subwoofer’s description from the manufacturer. Keep in mind, the peak power can only be used in short bursts, so you ought to look for a subwoofer with a high constant power.
Power deficiency is the number one reason why your subwoofer produces distortion and unappealing boominess in huge sound drivers.
The durability is dependent on the design of the subwoofer. If the subwoofer construction is enclosed, it will increase immensely the longevity of the product. Therefore, you should look for the subwoofer with a hard material. The ideal Medium-density Fiberboard is an excellent choice. And you should consider the speaker’s rubber as well, as it will make up your product’s stability. If your subwoofer is heavy-duty, it will not be prone to damage easily.
The rubber feet is also an essential part for your subwoofer as it will enhance the stability of your subwoofer. Metal corners, metal grille (steel preferred) will be the things you look for in finding a durable subwoofer.
Obviously, you cannot keep your subwoofer in one place, especially if you’re using it to play live performances or gigs, you pay attention to the subwoofer’s weight. You would want a lightweight subwoofer so you can carry it around. An ergonomic design is a suitable choice for those who move a lot. But if you only stay indoor and only want a subwoofer that is sufficient for your home studio or theater, you can skip this feature.
The suitable range of a voice coil you should be looking for in a subwoofer typically ranges between 3 inches and 4 inches. However, the voice coil only makes minimal difference to the sound, so if you’re not looking for a top-notch sound quality, voice coil could be something you want to pass. But keep in mind that although the difference is small it can definitely enhance your subwoofer’s performance.
Putting and installing the subwoofer or any devices are a challenging thing to do. To make it easier, make sure it comes with all the mounting tools if you’re buying it for your car. And for gigs, you should make sure that it also has a mountable pole.
Your Preferred Music
If you’re on the light, pop style of music, a 12 inches driver will be enough for you. The types of music like folk styles won’t be needing a lot of bass. But if you’re on the polar opposite, which is low-frequency, deep bass type of music like EDM kind of person, a more specific type of driver will be needed.
Passive or Powered Subwoofer
If you’re looking for a cheap version and already had an amplifier, then the passive subwoofer can be a great choice for you.Typically, powered subs come with amplifiers built-in so you don’t have to connect it up with another stub. But passive subwoofers, on the contrary, don’t have built-in amps so you have to hook it with an external amplification. But if you don’t have an amplifier already, you can pick the powered subwoofer, as it won’t need the external power to work like a passive one, but of course, the price can be a bit higher but this will reduce the hassle of finding and buying another external amplification.
Types Of Enclosures
Speaker enclosure should sufficiently separate the sound waves projects from those from the rear since these two sounds will cancel each other out; therefore, producing a horrible bass response.
You will find most of the car subwoofer is circular. You should be looking for a funneling directional sound type of shape since it produces a cleaner and less distorted sound compared to other types of subwoofer. And specially for cars, your traditional loudspeaker shape won’t deliver a better sound quality than a cone shaped one since the trunk of the car sometimes is even smaller than the typical bass cabinet.
You should opt for an already reputable brand in the industry. Because buying a subwoofer is a big investment for your sound system, you should consider who you are buying carefully. Most top brands will have the newest technologies to improve the sound quality by professional sound engineers. And most of the time, you will find the components made up of their subwoofer will be of higher quality than other subwoofers. This will help you to save a lot of money and reduce chances of components being broken or needed to be fixed and replaced after a long time of use.
