What is a Subwoofer and What Does a Subwoofer Do? 


The subwoofer is the most important component of a speaker system. It reproduces low frequencies and amplifies high frequencies. A good subwoofer has a well-balanced system. It should be placed in a central location so that the bass will not overpower the surrounding area. The surround will keep the cone centered and prevent any stress from being placed on the voice coil. Some people place their subwoofers in a specific corner of the room.

The right subwoofer can be matched with any speaker and will provide you with a high-quality sound. If you want to make the best sound possible, consider using a subwoofer with multiple speakers. It will give you a fuller audio experience.

What Does a Subwoofer Do?

In terms of sound, subwoofers are necessary to enhance the audio sound quality of a speaker system. The subwoofer should have dual voice coils for deep bass. Some people prefer a single-voice coil model for the best sound. In the end, it will depend on individual preferences. A subwoofer will not reproduce the bass of a single speaker if it has multiple speakers.

A subwoofer’s power is determined by its sensitivity. The higher the sensitivity, the deeper the bass. The more sensitivity, the more powerful the subwoofer will be. You should be aware of the noises produced by your speakers and make sure that they do not overlap. A good setup will allow the subwoofer to do its job without causing damage to your system.

A subwoofer’s frequency range is different depending on where it’s used. For home use, the frequency range is between 20 and 200 Hz. For commercial and professional settings, it’s around 100 Hz. Since it focuses on a narrower spectrum, it will not compete with other speakers. However, a subwoofer will make a sound system more complex. Because it will focus on lower frequencies, it will need additional speakers to cover higher frequencies. However, the subwoofer includes some features which enable it to perform well, these features include;

Features of a Subwoofer

The Motor

A subwoofer’s suspension system is supported by a motor system. The motor is what moves the components and supplies the necessary force. The voice coil, or spider, is the heart of a subwoofer. It is a thin copper wire wound around a cylinder. Audio signals are sent to a subwoofer by the amplifiers in the speakers. An electric current flows through the voice coil. This creates a magnetic field that pulls the voice coil against a gap of metal.

The Voice Coils

The voice coils in a subwoofer move upward and downward to produce sound. It is attached to a voice coil by an adhesive and extends outward to connect to the basket. The spider is also known as the “spider,” due to its corrugated design. In order to resist overheating, the fabric of the spider is treated with resin.

Where should a Subwoofer Be Placed?

A subwoofer should be placed in a central location for maximum output. The placement should have approximate volume and filter settings, and the subwoofer should be placed where it can produce the strongest bass. It is important to listen to the mid-range and upper bass notes to get a better understanding of the sound the subwoofer can produce. If they do not, you may need to relocate the subwoofer to a different part of the room.


The subwoofer is a key component in home audio. Without it, a full-range speaker is not effective at reproducing bass. A good subwoofer will help you hear the lowest frequencies. This can be difficult to achieve with a single-range speaker. Therefore, it is imperative to invest in a good quality subwoofer. A subwoofer will also make your music sound better.
