Do-it-yourself column filter: step-by-step instruction on how to make a column filter

First you need to understand the goals of this action, because now you can find speakers on absolutely any budget. But whether they are worth their money, regarding quality is a rhetorical question. For beginner musicians, activities often require better, sometimes at least correct, acoustics. In this case, you can try to create your own filter for the column.

What you need to know to create a filter in a column

Firstly - speaker system and general provisions:

• A person can hear frequency fluctuations from 16 to 20,000 Hz, higher frequencies reproduce smaller speakers, and low frequencies reproduce a subwoofer.
• A high-quality speaker system should consist of two or more high and mid-range speakers (speaker) and one low-frequency speaker (subwoofer).

It is also worth highlighting the types of speakers:

1. mono (one channel of sound supply);
2. stereo (Two channels of sound supply);

3. multichannel sound supply (mainly 5 speakers, 1 sub placed in different parts of the territory).

The filter is required when using stereo and multi-band speakers, for example, where one speaker is tweeter and the second is midrange. If connected without a filter, the tweeter simply cannot stand the lower frequencies and will fail. In the case of more similar speakers, the filter serves as a frequency distributor for the desired band.

How to make a do-it-yourself speaker filter

Follow the instructions to make a filter.

1. We calculate the components. To do this, use the calculator to calculate the parameters of the constituent elements (coils, capacitors, etc.), for example, “Crossover Elements Calculator”.
2. After the calculation, we select the capacitor for the desired parameter or collect from several into one parallel-connected unit (try to select not too different capacitors). According to the calculation of the induction parameters (in the same calculator), we wind the coil ourselves (diameter of the copper line, diameter of the rod, number of turns will be indicated).
3. Next, we look for the desired circuit, depending on how many speakers with the right frequencies you need.
4. We connect the coil and capacitor in accordance with the circuit and your speaker.

Now you can listen to high-quality, filtered sound, and be proud of a filter made by yourself.
