During the process of installing a new speaker system, the owner may have the following problem: how to connect tweeters (tweeters) so that they work efficiently and without problems?
The essence of the issue is the complexity of modern stereo systems. For this reason, in practice there are often cases when installed tweeters either work with distortion or do not work at all. By following the installation rules, you can avoid possible difficulties - the procedure will be as quick and simple as possible.
In what places is it recommended to install tweeters?
Manufacturers recommend many places to place tweeters, most commonly at ear level. In other words, aim them as high as possible at the listener. But not everyone agrees with this opinion. This installation is not always convenient. It depends on the specific circumstances. And the number of installation options is quite large.
- Corners of mirrors. During the trip they will not cause additional discomfort. Moreover, they will fit beautifully into the interior of the vehicle;
- Dashboard. Installation can even be done using double-sided tape;
- Podiums. There are two options here. The first is to install the tweeters in a standard podium (which comes with the tweeter), the second is to make the podium yourself. The latter case is more complicated, but it guarantees a better result.
Where is the best place to point tweeters?
When designing car audio, you can choose one of two options:
- each tweeter is directed at the listener. That is, the right tweeter is directed at the driver, the left one is also aimed at him;
- Diagonal installation. In other words, the tweeter on the right is routed to the left seat, while the speaker on the left is routed to the right.
The choice of one option or another depends on the individual preferences of the owner. To begin with, you can point the HF speakers towards yourself, and then try the diagonal method. After testing, the owner himself will decide whether to choose the first method or give preference to the second.
Use of asynchronous motors
Three-phase and single-phase asynchronous motors are actively used in various sectors of the economy. There are several reasons for this:
- Simplicity of design.
- Reliability and durability during use.
- In order to start the engine, there is no need to use expensive and scarce devices.
- The motor does not require too frequent maintenance.
By appearance, you can easily distinguish three-phase motors from single-phase ones. The former always have 6 terminals, while the latter have two or four.
For three-phase motors, the windings are connected in two ways: star or delta. They assume the use of a voltage of 380 volts. However, it is rarely used in everyday life. To use such a motor, you need to know how to connect it correctly.
This is done using a phase-shifting capacitor. This will allow the use of three-phase motors when connected to a single-phase network. In this case, the motor power will be equal to 50% -60% of the nominal.
Checking the starting capacitor Source antemion.ru
Optimal operation of a three-phase motor is ensured by using a variable capacitance. To do this, at the first stage, working and starting capacitors are used, and at the second, only the first of them.
Asynchronous single-phase motors are often used in everyday life. Additional winding is usually required to start.
When choosing the capacitance of a capacitor, it is necessary to take into account how the magnitude of the starting torque depends on it. As this characteristic increases, the force increases. At a certain value it becomes maximum. After a further increase, the starting torque will begin to fall.

Connection features
A tweeter is an element of a stereo system whose task is to reproduce sound with a frequency from 3000 to 20,000 hertz. The radio tape recorder produces a full spectrum of frequencies, ranging from five hertz to 25,000 hertz.
The tweeter can only reproduce high-quality car audio with a frequency of at least two thousand hertz. If a lower-frequency signal is applied to it, it will not be reproduced, and if the power for which the mid- and low-frequency speakers are designed is high enough, the tweeter may fail. At the same time, there can be no question of any quality of playback. For long-lasting and reliable operation of the tweeter, you should get rid of the low-frequency components that are present in the general spectrum. That is, make sure that only the recommended range of operating frequencies falls on it.
The first and simplest way to cut off the low-frequency component is to install a capacitor in series. It passes well the high-frequency frequency band, starting from two thousand hertz and more. And does not pass frequencies below 2000 Hz. In fact, this is a simple filter, the capabilities of which are limited.
Other Features
Today, the most common tweeter option is the electrodynamic system. Structurally, it consists of a housing, a magnet, a coil with a winding, a diaphragm with a membrane, and power wires with terminals. When a signal is applied, current flows in the coil and an electromagnetic field is formed. It interacts with the magnet, mechanical vibrations occur, which are transmitted to the diaphragm. The latter creates acoustic waves, and sound is heard. To increase the efficiency of sound reproduction, the membrane has a specific dome shape.
Car tweeters typically use silk membranes. To obtain additional rigidity, the membrane is impregnated with a special compound. Silk is characterized by its ability to more effectively cope with high loads, temperature changes and dampness.
In the most expensive tweeters, the membrane is made of thin aluminum or titanium. This can only be found on very prestigious speaker systems. They are found quite rarely in a typical car audio system. The cheapest option is a paper membrane.
In addition to the fact that the sound is worse than in the two previous cases, such equipment has an extremely short service life. And this is not surprising, since paper cannot ensure high-quality tweeter performance in conditions of low temperature, high humidity and high load. When the car increases engine speed, an unusual sound may be felt.
Don't forget that you can also set up the tweeter using the radio. Even the cheapest models have the ability to adjust the high frequencies. In particular, mid-price models have a built-in equalizer, which greatly simplifies the task.
After installing the tweeter, you need to configure the audio system, and how to do this, read the article “How to configure a radio.”
Installation check
Once a suitable starting capacitor has been selected, it must be tested. To do this you need to do the following:
- First you need to turn off the power from the electric motor.
- It is necessary to de-energize the capacitor, since a residual charge could remain on it. To do this, you need to short-circuit its windings.
- Now you need to remove one of the terminals and connect a device to measure capacitance.
- The probes are connected to the terminals of the capacitor. After this, the measuring device will show the exact capacitance value.
When using a multimeter, you must first set the main switch to capacitance measurement mode.
When carrying out calculations, you can use a simplified version. It is known that the starting current can exceed the rated current by 3-8 times. Therefore, you can simply use a capacity 2-3 times larger than that of the working capacitor. If the starting capacity is not enough, you can simply take a more suitable capacitor.

Video on how to install tweeters
Hi all. I recently wrote here with the question of connecting a tweeter without a condenser to an amplifier with a filtered input. I conducted a micro-experiment. And the croc simply connected a tweeter without a capacitor to the xylc, and then connected the same amplifier to the same tweeter via a condenser. Bottom line. I didn't hear or see any difference. Therefore, I believe that if you have a good filter at the input of the amplifier that can cut off everything below 4-6 kHz, then the tweeter works great. I don’t know what advantage this gives, but I still answered my question.
What are tweeters or tweeters?
If you have not used speakers before or made do with the classic versions, then most likely you are not familiar with the equipment called Twitter. Before buying it and installing it, you should understand the main purpose, advantages when listening to music and the operating features of this system.
From the name itself it is clear that during operation the equipment reproduces characteristic sounds of a certain frequency, similar to squeaking. This is achieved by incorporating high-frequency sound vibrations into the work. Since standard models have a wide range of usable frequencies, they make the music sound monotonous and desaturated. Therefore, special variations have been developed that can be used to emphasize high-frequency sounds, providing volume and expressiveness to audio recordings.
Twitter is a small speaker that is installed together with the main speaker system in order to improve the parameters and characteristics of the audio recordings being played.
ATTENTION! Depending on your preferences, you can install the desired number of such devices. For comparison, you can try listening to music through different speaker options to choose the best sound configuration.

Features of connecting tweeters
In general, this device has a fairly simple operating principle, which is based on the reproduction of sound waves in the high frequency range from 2 to 30 thousand Hertz. However, going beyond this range may lead to malfunctions. If at lower frequencies the sound simply will not be reproduced, then at higher frequencies it can lead to breakdown and damage to the microcircuits.
Therefore, for the correct operation and functioning of the system, there are some features in its connection. To avoid possible problems, you need to purchase a special capacitor that ensures that only the desired sound range passes through the tweeter.
IMPORTANT! Depending on the model of equipment and the sounds supplied to the equipment, capacitors may vary. It is better to consult with a specialist and select the necessary part that is suitable specifically for your column.
Also an important factor is the location of the tweeters relative to the main equipment. To compare, try several positions and find the most convenient location. It is recommended to place them closer than the main equipment in relation to the listener.
