Tips for choosing the best subwoofer

Some people must be familiar with subwoofer products installed in cars. However, what is a subwoofer? A subwoofer is a type of speaker that functions to play low-frequency sound or bass.

In addition, subwoofers have several sizes ranging from 15 inches, 18 inches, to subwoofers that can be placed under the car. You may be confused about choosing the subwoofer you need. Therefore, in this article, I will share Tips for choosing the best subwoofer.

How to choose the best subwoofer

There are various factors to consider when choosing a subwoofer. For more details, let's see my explanation on how to choose the best subwoofer below!

Choose your subwoofer by type

A subwoofer is a type of speaker so it works the same way as a speaker. So, before buying a subwoofer, you should at least know the type. That way, you can get a better idea of ​​what your subwoofer does so you can find the one that's right for you. For more, see my explanation about the following subwoofer!

1. More practical with an active subwoofer: An active subwoofer is a subwoofer in which an amplifier is embedded so that it is practical to use. You can directly connect the subwoofer with a sound source or other gadget to play music. The power used by the active subwoofer is not too large so it is suitable for everyday use.

In addition to everyday use, this type of subwoofer is generally used in cars. For those of you who are looking for a subwoofer for everyday use with a compact appearance, an active subwoofer can be your consideration.

2. Passive subwoofer for high-quality sound: You like sound with clear audio quality? If so, you might consider using a passive subwoofer. However, what you should pay attention to is that passive subwoofers don't have amplifiers built into them. Passive subwoofers can produce sound with good audio quality with the help of an external amplifier.

This type is generally used in home theaters or cinemas, where you need sound with added range or effect. If you use a passive subwoofer, you can adjust the number of speakers you use with the appropriate power. Of course, this cannot be done if you are using an active subwoofer.

To get the sound you want, pay attention to the subwoofer specifications

To get a subwoofer that suits your taste, you must first know the specifications. By knowing the specifications, you can understand the capabilities of your subwoofer. The basics about specifications that you should understand are sound pressure level, impedance and loudspeaker frequency response.

The sensitivity level or sound pressure is used to determine how loud the subwoofer can be produced. Sound pressure level is measured in dB. More conveniently, you can use a sensitivity level below 90 dB for indoors. As for open spaces such as fields, you can use a sensitivity above 90 dB.

Impedance is measured in Ohms (Ω) and affects how the audio system works. This is because impedance is a measure of the resistance of an Alternating Current (AC) source. The current that flows will affect the maximum power that can be issued by a circuit. A good optimal impedance measure for a subwoofer is around 6-8 ohms. However, it would be even better if the amplifier's capabilities were balanced by the subwoofer's impedance.

On the other hand, the frequency response is measured in Hertz (Hz) and indicates how low and high the sound can be played. The lower the number you have, the better the bass. On the other hand, the higher the number, the clearer the treble will be. So far, have you got an idea of ​​the type of subwoofer you need?

Pay attention to the quality of the Subwoofer box

Many people forget the importance of the subwoofer box, even though the subwoofer box can affect the sound quality. The subwoofer box should not be made carelessly because there are special calculations that must be adjusted to the volume of the main speaker box. The quality of the crib is very important because it can affect the quality of the subwoofer.

For example, if you have a good subwoofer, but the box quality is not good, then it will affect the sound produced. This is because the box can vibrate when the subwoofer is turned on so that the bass tone that is released is also affected. The right material to make your own box is usually made of wood, plywood, or MDF. Make sure you choose a subwoofer that fits your needs and budget!

Adjust the size of your subwoofer according to its placement

When going to buy a subwoofer, you should also consider first in terms of placement because subwoofers come in various sizes. There is a small size that you can place on a table or bookshelf. In addition, there is also a subwoofer that is used in the car to support the audio quality of your car.

There's also a large subwoofer to support your home theater speakers. You should also remember that the size of the subwoofer also affects the quality of the sound that will be output.

Subwoofers are generally used to maximize the bass sound emitted by the speakers. What do you think about the explanation of Tips for choosing the best subwoofer that I gave?

When you buy a subwoofer later, you should pay attention to the SPL (sound pressure level), impedance, frequency, and the box contained in the subwoofer. Also, it would be better if you try to check or look at other people's reviews before buying.
