Correct connection and installation of the tweeter. Installing the tweeter in the car How to properly connect pop tweeters
One of the most popular social networks in the world is twitter. Don't you know what it is yet? Never tried it, but want to try it? In this article, we'll look at a step-by-step action plan to master it. Twitter - how to use? Instructions for use
Basic concepts
Let's start with the basics. So what exactly is twitter? This is a social network, in another way you can call it a microblogging, where communication takes place with the help of short phrases and messages (tweets). With the help of them you can express your thoughts and emotions, share news, etc.
There is nothing difficult to figure out how this platform works, but to save time on conquering the vastness of the website on your own, I offer you a ready-made step-by-step instruction, using it, you will become a confident user of twitter.
First, let's take a look at the most frequently used words that describe actions in a microblog.
Tweet Is a short emotional message that will be displayed in the profile status. It is limited in the number of characters, that is, your message should be as informative as possible, but at the same time not exceed 140 characters.
Retweet - means to publish someone else's message in your status, where the person you are quoting will be indicated.
Both tweet and retweet will be visible to all our subscribers, who can comment and discuss your message if they wish.
Sponsored tweets - these are the same small phrases that express the general essence of what they want to convey to users. Typically, advertisements are posted on a hot topic list. The advertiser pays a certain amount for the advertisement to be visible. This is done in order to attract new subscribers.
Lists... In your account, you can group people into lists, such as classmates, relatives, colleagues, etc. This sort of sorting will make it easier to find the right person.
Hot topics. As a rule, this tab displays the most discussed and popular topics and news. When you click on a topic that interests you, a list of all statuses will drop out, where the topic you selected is mentioned. Messages that have collected more than 150 reposts differ from the rest in contrasting color.
Hashtags... In order for your tweet to be seen not only by your subscribers, but also by other users, you can put a sign after the message #theme name ... Hashtags are a kind of active links, by clicking on which the user can go to a page where all messages on the hashtag topic will be displayed.
For example, the European Football Championship is currently underway and there are many tweets and news on the hashtag # Euros2016.
Why keep a Twitter account?
You can use twitter for personal purposes, to maintain your own microblogging and communicate with friends, or you can promote and draw attention to your account in order to make money on the network.
To attract new subscribers, you need to subscribe to other users, leave comments on their page, so they can start reading you back. It's worth blogging more often and posting new tweets, responding to your followers and remembering that communication is the key to success. You can also resort to mutual recommendation to each other. That is, in your account you recommend a profile that interests you to subscribers, and this person, in turn, does the same, but already recommends you. This is a kind of mutual assistance to each other.

After you have chosen sports and news, for example, tweets of these topics will be displayed in your news feed.
Step 3.Relive your account. Let's upload your photo and add a header to the background.
Sizes of photos and headers for twitter:
It is not necessary to make such sizes. When you install pictures, you will be offered to scale and place the image as you like.
To change the page design, click on Change profile and customize the view for yourself.
In addition to the nickname, you can enter your full name, indicate a link to the site and put down geolocation.
About myself. It should be short and to the point, while still grabbing the attention of readers. Remember that the number of characters in the biography is limited to 160.
To do this, go to your profile page and put the mouse cursor in the line "What's new?" - We write our thoughts - click "Tweet" and that's it, the tweet is published) Now your message will be visible to subscribers who follow you.
The advantages of such a blog are that communication takes place in real time with real people, due to incoming notifications of new messages under your post, you will not miss a single comment. With the help of all kinds of client applications, communication on twitter is simplified.

The tweeter is a speaker for reproducing high frequencies (HF) in a car. Its sound quality changes depending on the angle at which it is directed towards the listener. We will tell you how to properly install the tweeter and achieve the desired sound.
Installing a tweeter is a trade-off in choosing the optimal angle and constantly fighting reflections. The correct setting affects the width and height of the soundstage, which affects the sound quality. The best place to install is the A-pillar. Meanwhile, on one side of the A-pillar is the windshield, on the other is the door window, which creates conditions for the reflections of standing waves. Therefore, let's talk about how to prevent them and choose the optimal angle.
Tweeter angle
Here is a schematic view of the vehicle interior from above. The straight axes of the two tweeters, shown in dotted lines, converge exactly midway between the driver and passenger seats at ear level. Sound should be heard clearly within 45 degrees between the front and side windows on each side. Since the listening angle is the same on both sides, the character of the sound from each side will be almost the same.
If the straight axis of the tweeter is at the same angles to the front and side windows, then the disturbance caused by reflections will be almost the same on either side. When installed at this angle, each end of the tweeter's frequency range will be closest to the listener.
Angle selection for tweeter installation
Here is a schematic representation of a listener in the driver's seat, side view. The straight axis of the tweeter is horizontal and is at the level of the listener's mouth. If the tweeter is turned up, or installed higher and turned down, then the phase can be greatly displaced and the integration of high frequencies with mids and lows suffers. If the tweeter is mounted at the level of the listener's mouth in sedan, coupe or station wagons, the tweeter and midwoofer may be aligned in a straight line. This helps to improve their interaction. When installing the tweeter, it is important to place it so that there are no reflective objects nearby within a radius of 5 cm. This helps to dramatically reduce the likelihood of standing waves in the high frequency region.
When a sound wave is reflected, a gap is created between the reflected and direct sounds. The reflected wave, which turned out to be 4 times longer than the rupture, takes a reverse phase. In this case, the sound pressure drops and the sound quality deteriorates. This is a standing wave. 5 cm x 4 \u003d 20 cm. The frequency with a wavelength of 20 cm is 1.7 kHz. Usually tweeters do not use this frequency. If you install it so that objects that can cause reflections are at a distance of more than 5 cm from it, the formation of standing waves will be minimized.
In addition, making a dimple closer to the top of the tweeter will help scatter reflections and reduce standing waves generated by reflections from the A-pillar.
How to get the right sound
How is the correct placement of the tweeter in the vehicle interior in practice? To do this, you need a test disk for testing your audio system, for example "Audio Doctor". There are special tracks on it - by which we will track the location of the tweeter and the correctness of the sound. For a start, it is worth temporarily fixing the tweeter to the front pillar anywhere - and then start testing.
Initially, to be determined with installation height... Playing a special track on a test disk, we observe the stage height. Move the tweeter up or down the stand - and thus check after each sound change. In any case, do not raise it too high - this way we will achieve a sound discrepancy between the midrange / bass and the tweeter. The closer they are to each other, the easier it will be to tie them together so that they sound evenly.
On the other hand, it is not worth lowering the tweeter low on the stand - the height of the music stage will deteriorate, which will negatively affect the sound volume.
It is important to determine the installation angle - the width of the scene depends on it. The most common arrangement is when both tweeters are facing each other. As with stage heights, there is no one-size-fits-all recipe to try different placement options.
Each car interior is universal and there is no single solution for installing a tweeter. We must try everything in practice.
In the process of installing a new speaker system, the owner may have the following task - how to connect tweeters (tweeters) so that they work efficiently and without problems?
The crux of the matter lies in the complexity of modern stereo systems. For this reason, in practice, there are often cases when installed tweeters either work with distortions or do not work at all. By adhering to the installation rules, you can avoid possible difficulties - the procedure will be as quick and simple as possible.
What is a tweeter?
Modern tweeters are a type of sound source whose task is to reproduce the high frequency component. Therefore, they are called so - tweeters or tweeters. It should be noted that, with their compact size and specific purpose, tweeters are easier to install than large speakers. They emit directional sound and are easier to place to create high-quality detail and accurate soundtrack that the listener will immediately feel.
Where are the tweeters recommended?
Manufacturers recommend many locations for tweeters, most often at ear level. In other words, aim them as high as possible at the listener. But not everyone agrees with this opinion. This setup is not always convenient. It depends on the specific circumstances. And the number of installation options is quite large. 
For instance:
- The corners of the 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 with double-sided tape;
- Podiums. There are two options here. The first is to put the tweeters on the regular podium (which comes with the buzzer), 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 direct tweeters?
When designing car audio, you can choose one of two options:
- every tweeter is directed towards the listener. That is, the right squeaker is directed at the driver, the left one is also directed at him;
- Diagonal installation. In other words, the tweeter on the right is directed to the left seat, while the left speaker is directed to the right.
The choice of this or that option depends on the individual preferences of the owner. To begin with, you can direct the tweeters towards yourself, and then try the diagonal method. After testing, the owner will decide for himself whether to choose the first method, or give preference to the second.
Connection features
A buzzer is an element of a stereo system whose task is to reproduce sound with a frequency of 3000 to 20,000 hertz. The radio tape recorder produces a full spectrum of frequencies, ranging from five hertz to 25,000 hertz. 
The buzzer can only reproduce qualitatively auto sound, the frequency of which is at least two thousand hertz. If a lower-frequency signal is applied to it, it will not be reproduced, and with a sufficiently high power for which the mid and low-frequency speakers are designed, the buzzer may fail. At the same time, there can be no question of any quality of playback. For durable and reliable operation of the tweeter, you should get rid of the low-frequency components that are present in the general spectrum. That is, to make sure that only the recommended operating frequency range falls on it.
The first and easiest way to cut off the low-frequency component is to install a capacitor in series. It passes the high frequency band well, ranging from two thousand hertz and more. And does not pass frequencies below 2000 Hz. In fact, this is the simplest filter, the possibilities of which are limited.
As a rule, the capacitor is already present in the speaker system, so no additional purchase is needed. You should think about buying it if the owner decided to get a used radio tape recorder and did not find a capacitor in the tweeter kit. It can look like this:
- A special box to which a signal is sent and then transmitted directly to the tweeters.
- The capacitor is mounted on a wire.
- The capacitor is built directly into the tweeter itself.
If you have not seen any of the options listed, you should buy the capacitor separately and install it yourself. In radio stores, their assortment is large and diverse. 
The range of filtered frequencies depends on the type of capacitor installed. For example, the owner can install a capacitor that will limit the frequency range supplied to the speakers at three or four thousand hertz.
Note! The higher the frequency of the signal fed to the tweeter, the more detail can be achieved.
If you have a two-way system, you can choose in favor of a cutoff from two to four and a half thousand hertz.
Connection
The tweeter connection looks like this, it is connected directly to the speaker located in your door, plus the tweeter is connected to the speaker plus and the minus to the minus, while the capacitor must be connected to the plus. This is a practical tip for those who don't know how to connect tweeters without a crossover. 
An alternative connection option is. In some models of car speaker systems, it is already included in the kit. If not available, you can purchase it separately.
Other features
Today, the most common tweeter option is the electrodynamic system. Structurally, it consists of a body, a magnet, a coil with a winding, a diaphragm with a membrane, and power wires with terminals. When a signal is applied, a current flows in the coil, an electromagnetic field is formed. It interacts with a magnet, mechanical vibrations occur, which are transmitted to the diaphragm. The latter creates acoustic waves, sound is heard. To improve the efficiency of sound reproduction, the membrane has a specific dome shape. 
Automotive tweeters generally use silk membranes. For additional rigidity, the membrane is impregnated with a special compound. Silk is characterized by the ability to more effectively cope with high loads, temperature extremes and dampness. 
In the most expensive tweeters, the membrane is made of thin aluminum or titanium. You can only meet this on very prestigious speaker systems. In a conventional car audio system, they are quite rare.
The cheapest option is a paper membrane.
Besides the fact that the sound is worse than in the two previous cases, such equipment has an extremely short service life. This is not surprising, since paper cannot provide high-quality tweeter performance in low temperature, high humidity and high load conditions. When the machine increases the engine speed, an abnormal sound may be heard.
Do not forget that you can also adjust the buzzer using the radio. Even the cheapest models have the ability to adjust the treble. In particular, mid-range models have a built-in equalizer, which greatly simplifies the task.
Video how to install tweeters
A tweeter is a speaker for reproducing high frequencies. Its sound quality varies greatly depending on the angle at which it is directed towards the listener. The high tones it emits with short sound waves are strongly influenced by various reflections. If there is any object that reflects sound a few centimeters from the tweeter, this will immediately affect the quality.
Installing a tweeter is a trade-off in choosing the optimal angle and constantly fighting reflections. If we can manage to position the tweeter at the most favorable angle and eliminate the possibility of reflections, then we have won this fight. Correct installation of the tweeter is important in both processor-based audio systems and conventional unprocessed ones. Correct installation of the tweeter determines the width and height of the soundstage, which affects the sound quality of the audio system as a whole.
Placing a tweeter in processor systems
It is believed that the best place to mount a tweeter is in the A-pillar. The reasons for this will be presented later. Meanwhile, on one side of the A-pillar is the windshield, and on the other, the door window, which seemingly creates conditions for all sorts of reflections. However, a reflection that contributes to the formation of standing waves is especially disadvantageous for a loudspeaker: when the waveform is reversed, changing its phase. And the high frequencies that the tweeter emits are very easily reflected from the surrounding objects, and as a result, standing waves are easily generated. Therefore, we will tell you how to prevent the formation of standing waves and how to choose the optimal angle when installing the tweeter.

Here is a schematic view of the vehicle interior from above. The straight axes of the two tweeters, shown in dotted lines, converge exactly midway between the driver and passenger seats at ear level. Sound should be heard well within 45 degrees between the front and side windows on each side. That is, since the listening angle is the same on both sides, the character of the sound from each side will be practically the same. In addition, since the straight axis of the tweeter runs at the same angles to the front and side windows, the disturbance caused by reflections will be almost the same on either side. By placing the tweeter at this angle, each end of the tweeter's frequency range will be closest to the listener.

Here is a schematic representation of a listener in the driver's seat, side view. The straight axis of the tweeter is horizontal and is at the level of the listener's mouth. If the tweeter is turned up, or installed higher and turned down, then the phase can be greatly displaced and the integration of high frequencies with mids and lows suffers. If the tweeter is mounted at the level of the listener's mouth in sedan, coupe or station wagons, the tweeter and midwoofer may be aligned in a straight line. This helps to improve their interaction.
When installing the tweeter, it is important to place it so that there are no reflective objects nearby, within a radius of 5 cm. This helps to dramatically reduce the likelihood of standing waves in the high frequency region.
When a sound wave is reflected, a gap is created between the reflected and direct sounds. The reflected wave, which is 4 times longer than the break, takes on a reverse phase, while the sound pressure drops and the sound quality deteriorates. This is a standing wave. 5 cm x 4 \u003d 20 cm, the frequency with a wavelength of 20 cm is 1.7 kHz. Usually tweeters do not use this frequency. If you mount the tweeter so that objects that can cause reflections are more than 5 cm away from it, the formation of standing waves will be minimized. In addition, making a dimple closer to the top of the tweeter will help scatter reflections and reduce standing waves generated by reflections from the A-pillar.
Choosing a place for the tweeter
Unlike a woofer and midrange speaker, the sound of a tweeter is highly dependent on the angle at which the sound reaches the listener. The described situation is especially typical for car speaker systems - due to reflections, standing waves arise, leading to the loss of musical information and sound deterioration. Considering all these features, it turns out that the A-pillar is the best place to install a tweeter in a car. If installed at the top of the door, even with a tweeter acoustic baffle of just 1.0 cm, the standing wave will dampen musical sounds with a frequency of 8.5 kHz. In this case, it will be difficult to maintain a symmetrical angle, and the frequency response on both sides of the tweeter will be very different.
If you make a large acoustic baffle and mount the tweeter at the bottom of the door using a surface-mount technique, where the speaker does not protrude above the screen, the chance of standing waves will decrease, but it will be completely impossible to achieve an optimal angle. Large-screen surface mount installation on a threshold panel also prevents standing waves. But if you do not raise the tweeter angle too much, the sound images will not reach the level of the dashboard, and if they do, then only the central image will be present at this level, and the side ones will be lower - where the midwoofer is located. Therefore, it is recommended to install the tweeter on the A-pillar at the correct angle.
How to get the right tweeter sound
Theory is theory, but how is the correct placement of the tweeter in the car? For this we need any test disk for testing the audio system, the most popular of which is "Audio Doctor". There are special tracks on it - by which we will track the position of the tweeter and the correctness of the sound. For a start, it is worth temporarily fixing the tweeter to the front pillar anywhere - and only then start testing. Each car interior is universal and there is no single solution for installing a tweeter. So he will try everything in practice.
Initially, you need to determine the height of the tweeter installation. When playing a special track on a test disk, we must observe the stage height. Move the tweeter up or down the stand - and thus check after each tweeter sound change. But in any case, do not raise the tweeter too high - this way we will achieve a sound discord between the midrange / bass and the tweeter. The closer they are to each other, the easier it will be to connect them so that they sound evenly in one frequency. On the other hand, it is not worth lowering the tweeter low on the stand - this may deteriorate the height of the music stage, which will negatively affect the sound volume.
It is important to determine the tweeter angle - the width of the stage depends on it. Most often in car audio systems, the most common scheme is opposite each other. This is when both tweeters are looking at each other. Here, as with stage height, there is no one-size-fits-all recipe; you need to try different tweeter placement options and draw conclusions.
Setting up a tweeter is a tricky business. If you are new to car audio and do not have an understanding of the correct sound in a car, tuning can take a long time. Don't try to do everything in one go, it's better to try more accommodation options and not in one day. After all, if you set up a tweeter today - and it seems to you that it sounds normal, then tomorrow the sound picture may change. So, the tweeter tuning process is very complex and multifaceted, but at the same time very exciting. And in order to achieve high-quality sound, you need to constantly improve and choose its optimal placement.
When the car owner decides to tidy up the acoustics, then he may have a question about how to connect the tweeters to the car. These tweeters are set to give the sound more beautiful tones. The problem with these sound-reproducing devices is their design and function. Connecting them is not difficult, but at the same time, a clear understanding of what and how should be done is required. Having installed and connected such a speaker with errors, you not only will not get a normal sound, but will quickly disable the tweeters. Therefore, it is important to select the right speakers and install them in the car carefully and carefully.
Device and varieties
How to connect tweeters to a car? Before answering this question, you should understand what it is, as well as what features such speakers have. After all, they use a large number of different technical solutions that are not used in midrange and tweeters. The correct name for tweeters is tweeters. The popular name comes from the sound characteristics of this equipment.
High frequencies start at 3 kHz. For example, the frequency of 4 kHz along the wavelength is 8.5 cm. The maximum frequency perceived by the human ear is 20 kHz, such a wave will already be equal to only 1.7 cm. Accordingly, to reproduce such waves, small speakers are required, but with minimal inertia ... Indeed, in the process of work, they need to hesitate rather quickly.
Nowadays, electrodynamic tweeters are most often used. At the heart of this speaker is a coil and a conductor. A core and a magnet around the edges. In this case, the coil is rigidly bound to the magnet. When current is applied, it begins to rotate in the resulting field, causing the coil to vibrate. This is how sound is made. For greater efficiency, the membrane is made in the form of a dome.
Automotive tweeters use mainly silk membranes. The material is impregnated with a special compound that makes the membrane stiff. The advantage of silk is its ability to withstand high loads, dampness and temperature extremes. The most expensive membranes are made from titanium or aluminum. Such options are used only in elite speaker systems. They are rare in car music. The cheapest option is paper copies, they have a bad sound, as well as a short service life.
Installation and connection
To carry out this work, you need a little tool, straight arms, and in some cases, even ingenuity. The tool will require the following:
- Shaped and flat screwdrivers;
- Insulating tape;
- Nippers;
- Wires (included);
- Lantern.
- We remove the trim from the doors. Usually it is attached with screws or clips. On some models, you will have to remove separately handles, ashtrays and other body kit. Removing the power window control unit is often problematic. Depending on the car, you must either gently pry its body with a screwdriver, or use a special puller;
- Having determined the location of the speaker installation, cut a hole in the casing;
- The tweeter is attached to the casing using double-sided tape;
- The most crucial moment is the speaker connection. Here, many make the mistake of connecting it directly to the radio. You can't do that. The radio itself delivers sound equally to all connected speakers, without any filtering. Therefore, not only high, but also low frequencies will be fed to the tweeter. At the same time, the sound will not be of high quality. Connection is made only through an amplifier. An additional wire should be pulled from the amplifier to the buzzer. If this is not possible, then you can route the wires through the crossover;
- You need to connect the wires strictly according to the diagram. Otherwise, just burn the tweeter. When connecting, be sure to insulate the wires, soldering will not be superfluous;
- After connecting, be sure to test the system, if everything works, then fix the wires and install the casing in place.
Additionally
When choosing a tweeter, you need to pay attention to some features of this equipment. For example, it is best to rate the sound at a quiet and medium volume level. This will best show the high frequencies. The same applies to configuring the assembled system. It is at low volume that you can adjust the frequency balance.
When choosing a tweeter, pay attention to the frequency response of the midrange speaker. They must necessarily intersect. Otherwise, you will get a "pit" in the frequencies, which will negatively affect the sound.
Conclusion... It's hard to imagine a modern car without music. In the process of arranging the acoustic system, car owners often wonder how to connect the tweeters to the car. In fact, there is nothing complicated here. It is enough to follow certain rules. Correct selection and connection of tweeters directly affects the sound quality.
