How to make a subwoofer with your own hands at home?

Today, when listening to any musical melodies, everyone wants to perceive the whole range of sound vibrations, which would not be complete in the absence of the most important device responsible for low frequencies. This is, of course, a subwoofer, which allows you to perceive any melody with great effect, both at home and in the car. That's why without a subwoofer, not a single musical installation is sold today. It may seem that its device is very complicated, but it is not so. On close examination, it turns out that the person who has elementary knowledge in the field of radio electronics will be able to make a subwoofer with his own hands.

So, in order to independently design a low-frequency device, we need the following materials:

- Directly a low-frequency speaker, the power and brand of which depends on what device you want to get in the end;

- low-frequency amplifier for a subwoofer;

- an audio signal processing unit for a music channel;

- plugs, sockets and terminals;

- Acoustic cable of wide section;

- A set for soldering.

As can be seen from the above materials, all this is in free sale, so it is not possible to get the necessary devices and elements of special complexity. Thus, a subwoofer can be made by yourself with your own hands at home, which is what many craftsmen do. Now we need to prepare everything that is needed to make the wooden frame of our low-frequency speaker. It is necessary to prepare a sheet of plywood with a thickness of 20 mm, screws, sealant, foam rubber and a screwdriver. After that, even if you are planning to make the simplest subwoofer, you should use the computer program JBL SpeakerShop, which will help you calculate the volume of the case. The latter should match the capacity of your system. This is an extremely important parameter and it is by no means to be neglected. You need to specify all the necessary data for those sound devices that you have purchased, and within a few seconds the program will give you the most optimal volume for achieving high-quality low-frequency sound.

It should be said that the subwoofer must be made from wood by its own hands, since this material is the best not only for the low-frequency device, but also for ordinary music speakers. After that, we mark out the plywood, cut it and assemble it with the help of screws and sealant. The back cover is last attached, since we pre-install the speaker connected to the amplifier and the sound processing unit. We lead the cables out and finally fix the back cover of the resulting speaker. Now it remains only to test our subwoofer by attaching it to the music center.

Thus, we found out how to make a subwoofer at home, using the materials available for the case. It should also be mentioned that when calculating the planned capacity, it is necessary to take into account the parameters of the room in which the device will be located. The main thing is the volume of the room, the presence of windows in it, as well as the material for finishing the walls. Be sure to review the recommendations for acoustic effects that can occur in rooms with too high or low ceilings, as well as in studio rooms.

By the same scheme, you can get a speaker for the car by making a subwoofer with your own hands. It is best to place it in the luggage compartment of your car, because in this case it will occupy a minimum of space, and the effect produced by it will be quite serious.
