How to make columns with own hands?

It is not difficult to make a good acoustic system, there is no need for scarce materials. Dynamics and building material are sold in specialized stores, and everything else depends on your imagination and diligence. The question is relevant at the present time, when there is a lot of technology on the market that does not match the parameters of your amplifier. On the quality of the goods can not speak, a good speaker system is expensive. Speakers can be made with their own hands even in the conditions of their own apartment, having selected their shape for the design of your interior. The whole event will cost much less than buying a new heaped-up speaker system. The advantages of a self-made device are also in the fact that you can calculate the maximum load for the amplifier and select the appropriate power dynamics.

We start, as usual, with the design. Columns with their own hands are first calculated on paper. Determine the power and choose the dynamics. If you want to design and make audio speakers with your own hands, then for the car it's best to use special car speakers. If you like good sound and expect speakers for use in an apartment or a private house, you do not need to save on the amplifier.

The ideal option, in my opinion, are tube amplifiers. They perfectly cope with their task and amplify the signal from the intermediate amplifier without distortion. Some firms continue their release, but they are quite expensive. Determine the power of the amplifier. We select the speakers in such a way that their total power exceeds the power of the amplifier itself. This will save them from premature failure. For the amplifier you do not have to worry, it has a built-in overload protection. Dynamics are usually selected according to the following principle. The high-frequency speaker is installed from above, then broadband and low-frequency, which is located closer to the floor.

Now a little about the material of the case itself. Columns with their own hands require careful attention both in the design and assembly. The denser the material of the case, the better the sound will be. You can take a sheet of particle board and directly to the dimensions. Do not forget that a well-designed speaker besides the speaker holes has small holes in the central part of the case. This is done so that when the speakers do not create a vacuum inside the case. If this is not foreseen, the sound will begin to distort, since an obstacle will be created for the free movement of the speaker membrane.

Now you need to install the speakers and cover them with decorative material on the front of the column. We stick decorative mosquito net or any other decorative material with our own hands. The main thing is that it freely skips the sound, and according to the design, it corresponds to the interior of the column itself. Now we glue the whole column with dermatine and uncoil the already installed speakers in parallel. Ring the input impedance of the speaker with an ohmmeter. If everything is OK, start the test by connecting it to the amplifier.

By the same principle, you can assemble the speakers for the phone with your own hands, of course, in this case there is no need to choose a high-power speaker.
