Self-made columns: diagram, drawings

At first glance, it's quite easy to make columns yourself. However, this is a delusion. First of all, it should be noted that the models are manufactured with different elements. Depending on them, the device parameters and sound quality will be different.

Special requirements are put to computer speakers. You can also make a model yourself for a car or a studio. In this case, it is very important to follow the instructions. First of all, for the assembly of columns, you should consider the standard scheme of the model.

Scheme of columns

The circuit of the column includes speakers, lining, diffuser and crossover. Powerful models use a special bass reflex port. Amplifiers can be installed with field or commuting transistors. In order to improve the sound quality, capacitors are used. The woofer is selected with an amplifier. The dynamic head must be attached to the seal.

Models with one speaker

Speakers with one speaker are very common. In order to assemble the model, you will first have to deal with the hull. For this purpose, plywood is often used. At the end of the work it will have to be sewn. However, first of all, you need to make side racks. For this purpose you will need to use a jigsaw. The speaker for the speaker can be selected with a small power.

The inner side of the plywood is necessarily sewed with vibration isolation tape. After fixing the speaker, the seal is fixed. For this purpose, glue is used. Then it remains only to attach the diffuser. Some for him make a separate shelf and fix it with stacking screws. To connect the speaker to the plug, a terminal strip is installed. How do I enable the speakers? To this end, a cable is used from the terminal block, which must lead to the power supply.

Drawing a model for two speakers

Speakers for two speakers can be made for home or car. If we consider the first variant, then the diffuser will need an impulse type. First of all, a strong plywood is selected for assembly. The next step cuts the bottom rack. Models with legs are very rare. You can use ordinary varnish to cover the veneer. Vibration insulation tape on the front rack is not required to glue. The diffuser is attached under the speaker. To make a hole in the panel, you need to use a jigsaw. Fazoinvertor fixed at the back wall. Some make devices with a horizontal arrangement of speakers. In this case, the diffuser will be in the upper part of the structure. The speaker wires are of two-wire type.

Devices with three speakers

Columns (self-made) with three speakers are very rare. These devices are most suitable for a multi-channel speaker system . For the assembly of the model, plywood sheets are first selected. Some also advise using veneers. However, models from natural wood stand on the market quite expensive. The speakers should be installed in a horizontal position. An amplifier is also required.

The metal corners are used to fix it. To connect the plates you will need tightening screws. In some cases, the plates are glued. Next, the model will have to be partially covered with leatherette. The next step is to install a terminal strip. For the purpose of fixing it on the body it will be necessary to make a separate hole. It is also important to note that there are models with regulators. The microcircuits for them are of the condenser type. When fonay columns, you need to change the diffuser.

Studio devices

Drawings of columns for studios assume the use of powerful speakers. The diffuser is most often used impulse type. Many experts recommend installing two amplifiers. For normal operation of the speaker system, you need a zener diode.

In order to assemble the columns in the first place, the case is first made. On the front panel for the speakers are made round holes. Also you need a separate output for the bass reflex. The design of the column is quite different. Some prefer the surface of the body to varnish. However, there are models covered with leather.

Models for computers

Columns for computers often make one speaker. For assembly of the model veneer sheets of small thickness are selected. On the front panel a hole for the speaker is cut out. Bass reflex should be located in the back of the case. If we consider low-power models, then the amplifier can be used without a resistor.

In order to adjust the volume of the speakers, special crossovers are used. These elements can be installed on the bass reflex. If we consider devices with a power of more than 100 W, then amplifiers can only be taken with resistors. Some for the model select impulse diffusers. At the end of the work, a terminal strip is always installed.

Car modifications

The speakers for cars are available in two or three speakers. For self-assembly of the model you will need sheets of plywood. In some cases, a veneer is used. To fix the speaker, you need to make a hole on the panel. The next step is to install a phase inverter. Some modifications are made with low-frequency cores. If we consider the columns (self-made) of low power, then the bass reflex can be installed without an amplifier.

In this case, a multi-channel crossover is used to adjust the sound. Some specialists install terminal blocks behind the bass reflex. If we consider a column with a power of more than 50 W, then the chips are applied to two amplifiers. The diffuser is standardly installed in a pulse type. Before fixing the case, it is important to take care of the vibration isolation layer. For the terminal strip on the plate, a separate hole must be made. Some believe that the building must necessarily be cleaned. Wires for the speakers are suitable for two-wire type.

Columns with an open housing

Portable speakers with an open case make it quite simple. Most often they are made with one speaker. On the back of the device holes are drilled. Directly the plates are connected by tightening screws. The diffuser for such devices is suitable for impulse type. Fazoinvertory often installed with a single amplifier. If we consider powerful portable speakers, then they use a resistor crossover. He is attached to the bass reflex. Many experts recommend that the speakers be installed on the seal.

Devices with closed housing

Columns (self-made) with the closed case are considered the most widespread. Many experts believe that they are the best in sound quality. Bass reflexes for devices are suitable for operating type. Woofers are installed in holes. For the purpose of assembling the case, conventional sheets of plywood are suitable. It is also important to note that there are modifications with cores. If we consider high power columns, the terminal blocks are installed in the lower part of the housing. The design of the model is quite different.

20 W models

It's quite easy to assemble 20 V speakers. First of all, experts recommend preparing six sheets of veneer. Cover them with lacquer at the end of the work. It is better to begin assembling with the installation of speakers. Bass reflex type is used. In some cases, it is installed on the lining. Also experts recommend to put rubber seals on.

The power of the speakers is provided through the terminal strip. It is attached to the back panel. Bass reflex can be installed with or without an amplifier. If we consider the first option, then the cores are selected phase type. In this case, you can not use the woofer. If we consider speakers without an amplifier, then they use a crossover. At the end of the work, it is important to clean the case and coat it with varnish.

50 W devices

Columns (self-made) by 50 W are suitable for usual acoustic players. In this case, the body can be made from ordinary plywood. Many experts also recommend the use of veneer from natural wood. However, it is important to note that he is afraid of high humidity.

After choosing the material, you should deal with the speakers. They are to be installed next to the bass reflex port. In this case, you can not do without an amplifier. Many experts recommend choosing only low-frequency crossovers. If we consider modifications with a regulator, then they use an impulse diffuser. The terminal block in this case is installed last. You can always use leatherette to decorate the columns. A simpler option is to cover the surface with varnish.

Columns with a power of 100 W

The 100 W speakers are suitable for powerful speaker systems. In this case, the phase-inverter is only impulse type. It is also important to note that the amplifier is installed with a crossover. Many experts recommend using a veneer for the assembly of the hull. Woofer is more convenient to install on the lining.
