Component or coaxial acoustics - what to choose for your car's audio system. Wideband speaker

Along with highly specialized speakers that reproduce sound from specific frequencies, there are full-range speakers that select mid frequencies as the main band, but connect both lower and upper frequencies to them. Of course, with cheap equipment the sound seems very poor, but if you buy high-quality equipment, you can improve it significantly. True, it is believed that such a mixing of frequencies in any case produces distortion, so such dynamic radiators are not suitable for special connoisseurs of high-quality music reproduction.

Basic information about full-range speakers

High-quality acoustics, which have a built-in full-range speaker, cover the entire frequency spectrum, without the need to overload the system with several speakers. This feature allows listeners to save themselves from having to buy a crossover, which is necessary to color the sound. In practice, such a speaker is quite enough for the sound to be rich, but a lot depends not only on the emitter, but also on the box and, in particular, the device manufacturer.

Thus, the English company Lowther produces truly high-quality broadband speakers that can compete with an entire speaker system. Products under the Fostex brand have also spread throughout the world and can be included among the top brands in this field. In addition to the above brands, speakers with full-range speakers produce:

• Saba;
• Jordan;
• Diatone Mitsubishi;
• Reps,
• Supravox;
• Kinap LOMO;
• Fertin;
• Radio Shack;
• Sonido;
• Noema;
• Telefunken and others.

True, not all speakers declared as broadband reproduce the entire spectrum of frequencies. For many it is necessary to purchase additional equipment in the form of a crossover or tweeter so that they are able to fully cover the audio range.

Types of Full Range Speakers

There are two types of full-range speakers:

• with central cap;
• with a cone-visor “dudka”.

The first resembles a simple speaker with a single dome cone built into it. The second has two cones, one of which is large, as in standard speakers, and the other, smaller, is located inside the larger one.

Additionally, full-range speakers can vary widely depending on manufacturer and design. This means that some speakers produce virtually no distortion and have high efficiency and sensitivity, but do not produce low frequencies well. To smooth out this drawback, it is necessary to develop a special box that increases bass. The high performance of full-range speakers allows you to limit yourself to low-power amplifiers (UP TO 3 W). Other full-range speakers deliver sound well across the entire frequency spectrum, but are less efficient. In addition, they require a stronger amplifier.

Is there a need for full-range speakers?

Broadband speakers are clearly inferior to their analogues, since one emitter cannot effectively convert the entire frequency spectrum. The result is sound distortion, lack of volume and depth. True audio connoisseurs are categorically against such devices, as they feel the difference in sound quality. But there are situations where full-range speakers can work just fine.

They are often used in cars, since not everyone can install a powerful speaker system in a vehicle, and not everyone needs it. To listen to pop music, there is no need to connect bass and high-frequency sounds. At the same time, distortions in the transmission of sound waves are unlikely to become the primary determining factor for equipping a car with a powerful and expensive system.

Full-range speakers are preferred by people who do not take sound quality into account. Medium frequencies are enough for them, which can be easily handled by radiators of this type, so they do not think about assembling an acoustic system consisting of several elements.

Comparison of full-range speakers from different manufacturers

If you set out to study the market for full-range speakers, you will find that it is not so rich in truly high-quality systems with a single speaker responsible for reproducing all frequencies. For example, Diatones produces similar devices, but they do not reach the high quality of bass conversion.

To a greater extent, speakers released in the 80s meet high quality standards. They capture low frequencies from 30 Hz, and reproduce high frequencies up to 16 kHz. Of course, this is not full coverage of existing sound waves, but it is enough for maximum color when operating a single speaker. This rarity is due to the fact that finding or creating a full-spectrum speaker is extremely difficult. You can get out of this situation by installing at least two speakers responsible for different ranges, but this already goes beyond the concept of a wideband speaker.

In this regard, most manufacturers who indicate that the speakers are equipped with a full-range speaker additionally build in elements that smooth out the speaker's shortcomings. For example, most add bass, but this also does not affect better side on sound quality. Mixing speakers is difficult to perceive by ear, while resonant vibrations from the subwoofer only spoil the sound of the mids and high frequencies.

Design features that enhance the quality of full-range speakers

As mentioned earlier, full-range speakers often focus on the mids and highs, while neglecting the lows. At the same time, most listeners strive to provide themselves with bass, too, so they resort to various tricks to eliminate this shortcoming. It is precisely because of the problems with the lack of bass that many do not consider speakers with a polypropylene cone, which does not perform well with positive side. The best speaker sound is achieved with a cone made of paper. A modern alternative is Kevlar.

When choosing a wideband speaker, you should pay attention to the diaphragm, which should not be large. The movement of the cone must also be moderate, otherwise there will be a problem with the transmission of high frequencies, which will also lead to significant distortion. To increase bass, you can increase the size of the cone while leaving the cone stroke at the same level. True, such actions will only help if a high-quality diffuser is built into the speaker.

For wideband speakers, it is best to use paper or plastic, for example, polypropylene, diffusers. Kevlar, aluminum and resin are also very popular. Paper is good because it does not have high rigidity like metal, but this reduces its resonance. To improve this parameter, the material can be varnished.

Thus, if you want to choose a full-range speaker, you need to be prepared for sound distortion. Quality device capable of producing the most acceptable sound, but finding it is almost impossible. For this reason, many strive to improve the emitter model by changing its internal parameters, which is always accompanied by the expenditure of time and effort, but does not in every case lead to a positive result.

Music in a car showroom is a common occurrence. Owners try to choose powerful radios for high-quality sound of tracks, forgetting that component acoustics – the sound reproduction system – should be the best. Car speakers may vary in design and quality. For example, there is a coaxial type of system - the most popular and easier to install. At its base there is a speaker with low-frequency sound, as well as heads for other frequencies. The sound from these speakers is average. The second type of system is component. It consists of mid- and high-frequency speakers that are excellent in sound and clarity. It's a little more complicated to set up, but the sound is ultimately better and richer. The rating included only the best component car audio systems according to the Mark.guru portal.

To make your purchase a joy and have a pleasant sound response, you should know about some selection criteria:

1. Stripes– are responsible for the sound quality and frequency of music from the speakers. The standard speaker system has 2 bands, but for higher quality reproduction there is also four-way equipment.
2. Material of manufacture. The best are considered to be wooden devices with silk tweeters. It is better to buy low-frequency speakers on pressed cardboard or paper. Particular attention should be paid to the presence of protective impregnation. The dome is preferably made of titanium, but the magnet should be made of neodymium - this will ensure good endurance.
3. Power. There is a nominal and maximum indicator. The first is a permanent working option for the speakers, and the second allows you to connect amplifiers and bass. The difference between the indicators should not be more than 3 times. Standard power is 50-150 W.
4. Size and shape. There are round, square and oval bases. Columns can be 13 cm, 16 or more. Small ones are sometimes more powerful and have better sound quality.
5. Manufacturer. You need to pay attention only to proven brands.
6. Price. Can vary from 2100 to 30,000 rubles.

In conclusion

So, to summarize: to select a component speaker system, you should decide on the size - this significantly affects the installation. Popular models with low cost and at the same time simple design. If the goal is to obtain sound quality, then it is better to choose French and German assemblies. They are able to satisfy the most demanding tastes, and deliver heavenly bliss from playing any composition. Both types of acoustics can be found in this review.

Driving in a car without music turns into real torture. At the same time, each car enthusiast has individual requirements for sound quality. Some are satisfied with a light musical “background” in the background, while others need clear and spacious sound.

That is why, when choosing acoustics, the question becomes which option to give preference to - coaxial or component acoustics.

What is coaxial acoustics?

Coaxial acoustics is a stereo system based on two or more acoustic devices capable of operating at different frequencies, combined into one design.

It is believed that multi-way speakers produce better sound. But that's not true. Practice has shown that increasing the number of speakers (more than two) is pointless.

Coaxial acoustics have a number of advantages - ease of installation, emission of frequencies from one point, and so on.

The downside is the placement of a tweeter (two or more) in the path of sound waves emanating from another (midbass) speaker, which is located at a lower level.

In addition, such acoustics are equipped with the simplest version of crossover filters.

Examples of coaxial acoustics:

• Pioneer TS-1339R - speakers that are suitable for owners of locally produced cars. The set includes two round speakers measuring 130 mm. The installation depth of the device is 5.53 cm, which simplifies the installation process. The diffusers of coaxial acoustics are made of polypropylene, and the suspension is based on NBR rubber. The acoustics belong to the three-way series, which opens the way for the use of speakers of different frequencies (low, medium and high). The maximum (nominal) power is 200 (40) Watts, respectively. Frequency - 40 Hz-30 kHz. The speakers have a standard impedance of 4 ohms. An external crossover is provided. The structure is installed in factory holes.

  

  

• Coaxial speaker Sony XS-FB1330 is an acoustic system that has a low price and high quality. This system will please fans of “deep” music. It is distinguished by its compactness, functionality, and build quality. The coaxial stereo system has two black speakers. The diameter of each of them is 13 centimeters, the seating depth is 4.5 cm. The advantage of the Sony XS-FB1330 is the presence of a powerful diffuser in the woofer, made of rubberized fabric and shaped like a cone. Thanks to this, you can count on rich and deep sound. The speaker power reaches 240 W, the sensitivity level is 89 dB. The Sony XS-FB1330 does not cause installation problems, thanks to its compact size and the absence of a subwoofer and amplifiers.

  

What is component acoustics?

Component acoustics are a stereo device that includes 2-3 speakers (sometimes there are more than three, but this is rare).

The main difference is the separation of speakers by frequency into separate devices. In this case, each speaker emits sound in an individual range, which eliminates the intersection of frequencies.

Component speakers are manufactured using modern technologies. The kit includes crossovers that guarantee higher quality sound.

Thanks to frequency separation, there is room for maneuver when placing speakers, which ensures the creation of a single sound “picture”.

Installation of such systems causes difficulties for car enthusiasts, but the sound quality is better.





Examples of component acoustics:




What is the difference between coaxial and component acoustics?

The main difference between the two systems, which is worth highlighting, is the location of the sound sources in the cabin in relation to each other.

The overall design of coaxial speakers guarantees highly focused sound, which is why the speakers are mounted in a special shelf behind the rear seats.



A component speaker is usually installed in front.



Unlike the coaxial system, the component system provides super surround, that is, surround and high-quality sound distributed throughout the cabin.

The problem is that each speaker (woofer, midrange and tweeter) reproduces sound at an individual frequency, which requires adjustment.

In a coaxial system, the frequencies are combined, which is why the sound is no longer as clear.

As practice shows, for cars with a small interior, a component speaker is not suitable due to the lack of difference in quality (there is no point in spending more).

Worth highlighting technical difference, which consists in the presence of a crossover.

In coaxial systems it plays the role of a filter. In addition, in component speakers it is external, and in coaxial speakers it is internal.

Another difference worth noting is the type of installation of the device. It’s difficult to call the acoustics that are installed at the factory a stereo system.

A coaxial or component sound system is the responsibility of the car owner. Installation will require some knowledge, but with the right approach and following the main principles, problems rarely arise.

When installing component acoustics, it is worth considering the presence of acoustic zones. In this case, a prerequisite is the installation of shelves and.



The sound quality also depends on the radio itself.

The worse the output quality, the less meaning spend time and money installing an expensive component system (there will be no difference in sound).

But if a car enthusiast is not very demanding on quality and makes do with a radio or an ordinary chanson on the road, then coaxial acoustics are just right.

The key factor when choosing is the price of the speaker system. It's easy to make a comparison here.

Component speakers are more expensive than their “younger brothers”. In addition, its installation causes certain difficulties for car enthusiasts. The exception is transformer systems, which convert component acoustics into coaxial ones using special fasteners.

So, the speakers have the following differences:

1. In a coaxial speaker, the speakers produce sound at different frequencies that come from the same device. In a component speaker, each speaker is autonomous.
2. Coaxial acoustics guarantee narrow directionality of sound, and component acoustics guarantee surround sound.
3. Coaxial speakers are equipped with a built-in crossover, and component speakers are equipped with an external one.
4. Installation of component acoustics is more complicated and requires certain knowledge.
5. The cost of coaxial speakers is lower.

Which acoustics are better - coaxial or component?

Which one acoustic systems to give preference, each car enthusiast decides for himself (taking into account personal preferences).

Coaxial speakers are simple in design and easy to install. In this case, HF and LF are emitted by one speaker.

Advantages - low price. The downside is the average sound quality and limited customization.

Component acoustics is an advanced option, which includes speakers emitting different frequencies and a crossover used for frequency separation.

The thoughtfulness of the design opens the way for experimentation with sound quality. All that is required is to choose the right location for the speaker and the place to install it.

Such speakers are expensive and require a careful approach to installation (as a rule, the work is performed by specialists).

If there are no special requirements for purity and sound quality, then coaxial acoustics will be sufficient.

True music lovers who are demanding of sound and are accustomed to listening to their favorite music on elite-class systems should opt for component acoustics.

When choosing a speaker system for your car, follow a few tips:

Results

Powerful, clear and spacious sound in the car interior is still worth earning. To do this, it is worth spending time on choosing acoustics, choosing a place for installation and, in fact, the installation itself. At the same time, do not skimp on quality and attracting craftsmen.

The disappointment from incorrect installation will be greater than the resentment from the money spent on the master.

When upgrading their car audio system, quality music lovers are replacing existing devices. In the process of car tuning, it is impossible to replace one type of equipment; any changes entail an improvement in other components of the sound system. The most important criteria when choosing radio equipment are the quality of music reproduction and the price of the speaker system.

Speakers for component acoustics

The professional term “component acoustics” means speakers with broadband, high-frequency emitters assembled in one housing. The name, which characterizes the differences between coaxial and component speakers, has also taken root in the trade designations of diffusers.

Replacing low-quality standard speakers is the first step in acoustic tuning. Without changing the factory car radio, you can use inexpensive coaxial speakers (they have a high-frequency diffuser built into the broadband) or two-component acoustics.

In terms of sound quality when selecting a signal from standard car radio budget models, only a specialist can distinguish between coaxial and component speakers. But even relatively inexpensive component speakers in cars last much longer than coaxial speakers.

2-component acoustics (which is correctly called “two-way”) combines two diffusers in one housing, allowing you to reproduce both high and mid frequencies. For background listening to music, a two-component system is sufficient, but it does not meet the high requirements for the quality of overtone transmission.

A complete set of two-component acoustics includes:

• two tweeters (professionals often call tweeters “tweeters”);
• two midbass (bass/midrange speaker with a range of 50 Hz - 3.5 kHz);
• two passive two-way crossovers.

Most inexpensive standard radios It is not equipped with built-in crossovers, which must be purchased separately. A device combining an inductor and a capacitor is necessary to accurately separate the frequency spectrum.

To this set, 3-component acoustics add two midrange and mid-range speakers for reproducing the mid-range (frequencies 150 Hz - 1 KHz). To complete three-component acoustics, you will also need to replace two-way crossovers with three-way ones.

Both dynamic sound wave reproduction systems are designed for frontal placement (in the front of the cabin). They can be installed in door panels (in place of standard speakers), above the dashboard, on the side pillars of the windshield.

When creating a three-lane front for the third pair (midranges), you need to think about the installation location. In addition, midrange models without a phase-equalizing tip will require the manufacture of a three-dimensional body. Most often, the third pair of speakers is installed on the central tunnel of the cabin. Install midranges near rear window It's pointless, it will degrade the sound volume.

Component acoustics in practical use

Two-component car acoustics in a car can improve the sound quality and volume slightly. For noticeable results, it is necessary to purchase and install a high-quality head unit.

The possibilities of three-component acoustics are wider, but even here a significant jump in quality will only be achieved by channel-by-channel amplification. Connecting each device to a separate channel of a four-channel or eight-channel amplifier, completing the system with filters, correct setting time delays - provide quality comparable to listening to a high-quality home audio system.

In the lower price segment the best component acoustics from the brands Audison, Challenger, Kicker, Polk Audio, Alpine cost $80 - $210. The advantages of inexpensive but high-quality speakers include decent maximum power (up to 300 W), silk dome tweeters, the ability detailed settings, size (available for installation in standard places of serial foreign cars), compatibility with various amplifier models.

When choosing component speakers, important characteristics are:

• equipped with an external crossover;
• aluminum diffuser;
• magnet power;
• cast basket;
• chromed back;
• Convenience of mounting holes;
• durable protective grilles;
• swivel tweeter design.

User reviews consider the advantages of various midbass models to include additional mounting and installation devices. For installation on domestic car models, a small installation depth is important.

Car audio lovers consider the common disadvantage of all component speakers to be manifestations of crossover defects and insufficient bass depth. The design disadvantages of some models will be short tweeter wires, demands on the precise direction of sound, high sensitivity of the coils, close location to the core (manifested in squeaks after washing the car). Larger remote crossovers may require special sockets for installation.

Installing component speakers in a car showroom

Installing speakers in door panels faces certain challenges. If you do not want to redo the door panel, it is better to first remove one of the speakers in order to be guided by its dimensions. For domestic models(in particular, the tenth VAZ family) the installation location is designed for speakers with a diameter of thirteen centimeters. Most foreign manufacturers produce high-quality component diffusers measuring 6 inches (16 centimeters).

In addition, it is necessary to redesign the mounting systems that do not prevent the speakers from rattling.

To install a new imported speaker you need:

• disassemble the door panel;
• cut off the installation location;
• trim and straighten the stiffener;
• plan the installation location of the speaker (the best location is considered to be towards the center of the cabin);
• close and seal the technological holes (use masking tape, fiberglass, epoxy glue);
• install a complete or homemade podium under the speaker (necessarily a tight fit to the door metal);
• improve the sound insulation of the door (glue the internal surfaces with vibroplast or other sound insulator);
• install speaker;
• mount a crossover (installed next to the midbass);
• cut holes in the door panel for diffusers and cables;
• assemble the door;
• strengthen protective grilles;
• decorate the door panel from the outside.

A homemade podium can be assembled from several plywood rings of various diameters (repeating the configuration of the speaker), held together with an adhesive joint. For the bottom ring, it is necessary to provide ears with holes for fastening. In foreign cars, new speakers are usually installed in standard places. An improvement could be the manufacture of a more massive wooden podium.

The location for installing tweeters must be selected individually, depending on the interior of the car. On a Zhiguli, a triangle near the mirror shift control can be a convenient place, although this arrangement lacks a little sound stage height. The protruding standard “cup holder” of the tweeter can be replaced with a homemade podium of an original shape, glued together from fiberglass with epoxy. For the wire you need to make a hole from the door panel.

Perhaps many of you, dear readers, have repeatedly wondered about improving the acoustic situation inside your car. Agree, when long trip, sit in complete silence not that much fun, so the minimum that can be done in such a situation is to install a regular inexpensive radio in advance. With its help, you can listen to your favorite music, learn about events in the country, or get a weather forecast for the next few days (provided that it supports radio communication). However, to ensure high-quality sound from the car radio, you will have to use additional devices, called an acoustic system. Today we will discuss one of its options, which is presented in the form of a broadband (or as it is also called “single-way”) speaker system.

The path of development of speaker systems: from broadband to multi-band

Wideband speaker systems are presented in the form of broadband speakers, in which an electrical signal is supplied to the speaker without pressure on the frequency bands - high and low frequencies. At the beginning of their history, almost all speakers had high sensitivity and were defined as broadband, however, as sound production technology developed and improved, speakers with one speaker, which was responsible for the entire sound spectrum, were supplanted by an acoustic system that divided the sound into two bands. To achieve this effect, they began to use a special device - a crossover.

Individual speakers of speakers of this kind had different designs, were made of different materials and were engaged in servicing their individual sub-range. The lower speaker, with a larger area and density of the diffuser, controlled low and medium frequencies, and the upper one was responsible for high frequencies. With the further development of acoustic systems, band separation of sound continued. This was the reason for the emergence of speakers with three, four and even five sound bands, which were called “multi-band”.

If we analyze this concept more precisely, then in our time, pure broadband speakers are found only in “radio points”, but from the point of view of marketing, which has made some adjustments to the definition of “broadband speaker system”, many other speakers fall into this category , which are essentially two-lane. The passing signal, with the help of a crossover, is divided into two bands and fed to two corresponding speakers of different designs - the task of the upper one is to control the operation of high frequencies, and the lower one is responsible for low and medium frequencies. However, there are also speaker systems that, although they have two bands and two speakers, are not called broadband. What's the matter?

It seems to us that in the modern world, it would be most correct to define “broadband acoustics” not from the technical side of the issue, but from the marketing side; moreover, the technical version was already voiced at the beginning of this article.

And so, a modern wideband speaker system, as a rule, is a floor-standing or large bookshelf speaker with no more than two high-sensitivity speakers. The speaker responsible for low and mid frequencies is equipped with a thin, lightweight diffuser (usually paper) with a significant area. Its task is to reproduce most of the sound spectrum - from drums to vocals. The speakers that control the high frequency also have a fairly significant area. Although they are somewhat smaller than low-frequency ones, you will not find any “tweeters” or metal diffusers the size of a penny in broadband acoustics.

The lightweight diffusers available in such speakers can transmit the most subtle musical moments - vocal overtones, noticeable string plucks, etc. When listening to wideband acoustics with a good reproduction path, it may seem that you can hear rosin falling off the violinist’s bow, that is, wideband speakers are ideal for reproducing classics and light live music, which is why many audiophiles love them so much. However, despite all the advantages, there is a “but” in almost every issue.

Here too, speaking about the sensitive cone of wide-range speakers, one cannot fail to note the lack of its density, which means it is impossible to transmit powerful guitar riffs and driving drums of hard rock. Moreover, such music is generally contraindicated for this acoustics. All that can be heard is a loud performance that will not bring even the slightest pleasure. If the car owner is a fan of hard music or heavy blues, wideband speaker systems will not suit him. It would be better to pay attention to multi-band acoustics.

Additional components of any speaker system

As you already understood from the previous question, installing conventional wideband speakers will not completely satisfy anyone, so many car enthusiasts whose cars are equipped with standard speakers are either looking for ways to strengthen them or replace them with more advanced sound emitters. In this matter, I would like to pay special attention to the 6*9 speakers, or as they are more often called – “”. This type of emitters is designed to reproduce deep bass sounds. As a rule, low-frequency speakers of this kind have a large diameter and a large diffuser area.

A car subwoofer is one of the most the best ways sounding of low frequencies, helping to get good bass. Most motorists install a subwoofer in their vehicle in order to obtain not only high-quality deep bass, but also mid and high frequencies combined with it, which only good acoustics can produce. Currently, there are two types of subwoofers: active And passive. The active device has a subwoofer speaker placed in a finished housing. It has a built-in amplifier and active crossover. Passive subwoofer presented in the form of one subwoofer speaker, without any additional elements.

Before you decide to purchase a subwoofer for your car, you need to decide on its size, dimensions and optimal power. Pay attention! For better installation and better sound, car subwoofers require a specially prepared housing.

Another popular addition to a speaker system is a crossover (sometimes called a “filter”), which consists of a capacitor and inductor tuned to a specific frequency. Why capacitors and coils? Yes, because they are the simplest reactive elements capable of differentiating signals (capacitors are responsible for high frequencies, and coils for low frequencies). Skillful control of signals turns a crossover into a simple frequency filter.

Most often, it is the main component of a multi-band audio system, as it is responsible for dividing the incoming signal into different frequency ranges. Respectively: the more channels in the crossover, the more speakers and the more interesting the overall sound atmosphere will be.

Wideband acoustics and its design

To reproduce high quality sound signals, full-range acoustics use just one speaker, which is capable of covering the entire audible frequency spectrum. This feature eliminates the need to use a crossover, which, by the way, many people consider one of the worst things in the world of audio sound. Of course, from a practical point of view, it’s not bad when one speaker can provide high-quality sound, but for this, the design of the box must be appropriate.

There are two main types of full-range speakers: cone-visor(or simply “pipe”) and with central cap. A wideband speaker with a cone weeper includes two cones - a large one (the same as in normal cone speakers) and a slightly smaller weeper cone located inside the large one. The second option, with a central cap, looks like an ordinary simple speaker, only with a cone dome (central cap).

The characteristics of certain broadband speakers vary from one another and depend on the design features and manufacturer. Some of them have quite high level efficiency and sensitivity, low level distortion and frequency response plot, indicating a reduction in sound pressure levels in the mid and low bass. This factor is the reason for the need to use a special box that enhances bass.

But despite some disadvantages, the high sensitivity of wideband speakers allows the use of amplifiers with very low power (from 0.5 to 3 W tube amplifier). Other representatives of wideband acoustics have lower efficiency, but at the same time have a good frequency response. Typically, such devices can be used in an open box or bass reflex box, but will require a stronger amplifier.

Today, there are few true (namely full-spectrum) wideband speaker systems that could reproduce high-quality sound using just one speaker. Most of them are essentially "full range" and ultimately require two sources: one speaker for the low frequencies and one for the high frequencies.

As we noted earlier, standard wideband speakers quite often do not provide the optimally desired sound quality of music, so many car owners have to change the standard speakers to stronger devices. In such cases, in addition to the effectiveness of the new speakers, an important point is the acceptability of their pricing policy, because no one wants to pay more.

I think we don’t have to talk about the wide variety of representatives modern world car speakers, because every car enthusiast who has been interested in this issue at least once already knows about it. Therefore, in order to really choose what you need, you should approach the issue of purchasing a device extremely responsibly. If the driver does not have too high demands on music, then the most correct decision would be to buy broadband speakers: they are cheaper and the installation process does not require special skills, which means it can be done independently. To listen to news or music from radio stations, such devices will be more than enough.

In order to correctly carry out the procedure for installing speaker systems, it is important to take into account the size of the speakers. The standard size is the standard that determines the size of car speakers. As is known, in most vehicles, the manufacturer already provides standard places for installation, but their size is intended only for oval or round speakers of 10, 13 or 16 centimeters.

Pay attention!The larger the speaker, the better it will reproduce low frequencies, that is, in general, the size is determined by the size of the low frequencies of the speaker. When purchasing broadband acoustics, most often, instructions are included with it, which describes in detail the entire process of the upcoming installation. Before moving on to installation, you can further study photos and videos on the Internet. Another advantage of broadband acoustics is that their price is always lower than multi-band acoustics.
