What a Subwoofer is and why it improves your sound system
Subwoofers are loudspeakers capable of emitting sound waves that add depth to the reproduction of your music. Subwoofers reproduce medium and low tones that are not normally emitted by woofers. For more references, check out: best powered subwoofer for cars
A good sound system is not necessarily one that reproduces audios with more volume than the others. Part of the reproduction of high quality audio is related to the ability to reproduce different low and high tones that are perceptible to the ears, to provide the listener with the sensation of sound depth and immersion in the environment.
In a well-configured sound system, subwoofers perform the important function of emitting serious and perceptible sound waves to the ears, adding sound layers to musical reproduction. The subwoofer speakers are present in Home Theaters, soundbars and in automotive sound systems and in this text we explain why they are so important and how they improve the sound experience.
What is subwoofer
The subwoofer has this name because it is a type of speaker responsible for reproducing sounds at frequencies between 20 Hz and 200 Hz, below the sounds reproduced by woofers. These speakers are very easy to identify in sets of speakers as in Home Theaters, because normally the size of the subwoofers is larger than that of the other speakers, so that the displacement of the existing cone inside the box can move more air while vibrating and, thus, emit lower frequencies of sound.
There are subwoofers with different cone diameters, with 8, 10 and 12 inch diameter round cone ones being more common in the market. In subwoofers with larger cones, the amount of air moved is greater, generating greater sound power in sub bass waves, but with a slower response time, while the opposite result is obtained in smaller diameter cones.

Subwoofers can be divided into two categories, passive and active. Liabilities do not have their own amplifiers and do not need an exclusive source of energy to function because they receive the already amplified sound from the device to which they are connected. Unlike active subwoofers which, although they need their own power supply, allow more detailed adjustment in their settings and are equipped with their own amplifier.
What is the subwoofer for?
More than just emitting sound waves at low frequencies below those emitted by woofers, subwoofers are essential in high quality sound reproductions, as they enrich the sound experience by adding bass at intensities that other sound devices cannot reproduce, making the sound more intense and vibrant.
To understand the difference between sound systems with and without a subwoofer, remember the sound emitted by simpler cell phones and notebooks. These devices do not usually have subwoofers and despite the musical reproduction, the impression of audio without depth and without layers is left.
Not by chance, all Home Theaters and the best quality soundbars have a subwoofer box in their set of speakers. The immersion and cinema sound experience intended mainly by the Home Theater can only be achieved through the emission of bass sounds by the subwoofer box, which, unlike the other smaller boxes that form the sound set, does not need to be directed to the listener.
In automotive sound systems, the subwoofer is also responsible for adding richness and sound depth, removing the impression of “dry” music present in systems composed only by woofers. The serious waves that travel shorter distances are ideal for small and closed environments such as the interior of cars.
