In this article, we will consider in detail how to make a subwoofer with your own hands, if there is no professional knowledge in the field of electroacoustics and there is no desire to use previously unknown and incomprehensible schemes, although of course you still have to make a few measurements.

What is a subwoofer and for what purpose is it used?
The subwoofer is popularly called simply a subwoofer, and if you translate this word verbatim, it sounds funny enough - an add-on. In fact, this is a real bass speaker, characterized by a low frequency, decorated in a special box with an extremely complex device.
Today, if you look at the photo of the subwoofer with your own hands, you can see that they are used in a huge number of different places, ranging from simple everyday situations, when it is installed at home and ending with the fact that today many people use subs in their cars.
If you can find a good drawing of the subwoofer and make it right, then you can definitely take on almost any speaker complexity, since it is the reproduction of bass that is one of the most difficult moments in the world of electroacoustics.
It is only important that the subwoofer circuitry fully meets your idea of perfect acoustics.
A little bit about bass
Playing various basses is, in principle, a rather difficult process. In general, the LF section of absolutely any spectrum of sound waves available differs depending on its psychophysiological strong impact on several areas.
In order not to make a mistake in choosing a bass, truly high-quality speaker, and subsequently the box for the subwoofer was able to be completed quickly enough, first of all, it is necessary to mean their key value and corresponding boundaries.
Depth
For various kinds of wind organs in halls specially repaired for musical instruments, a sub-bass has a significant influence on how the timbre of sound will be. It is for the sounds of nature and various technological disasters, such as unexpected explosions that are characterized by sufficiently strong sub-bass components.
It is worth noting that most people do not hear sub-bases at all, or they hear, but not well enough. For example, if we filter out the fundamentally different in nature sounds of a nuclear explosion and a strong hurricane, like a tornado in the tropics from everything except sub-bass, then we can say with absolute certainty that it is unlikely that any of the listeners will be able to understand that it actually happens.
For this reason, almost everyone optimizes the subwoofer for the home exclusively on midbass.
How to choose a speaker?
When choosing, it is worth paying attention to the fact that the full calculation of the entire acoustic design is always performed only according to the known Thiel-Small parameters.
When creating a good subwoofer on your own, it is only important to take into account the absolute quality factor of the head precisely at its main resonant frequency. This is due to the fact that it is used to select the ideal option for future acoustic design.
Car subwoofers
If you are interested in car subwoofers, then in this case it is worth bearing in mind that they are most often installed either directly under the driver's seat or in the trunk compartment.
When placing the second option, the car subwoofer can take up a lot of useful space, so they resort to it less often.However, in the case of placing the subwoofer under the seat, there are some risks associated, for example, with the fact that it is easy enough to damage your feet in this case.
It is worth paying everything else special attention to the important point, namely, that in a fairly cramped passenger compartment you can not do without the mandatory effect of masking various noises.
For this reason, almost all car subwoofers are optimized primarily for the subwoofer.
In conclusion, it is worth noting that, in principle, anyone can make an amplifier for a subwoofer on their own and this will be a rather amusing activity, useful not only for the development of skill, but also of the mind.
