• Difference between coaxial and component acoustics. Component acoustics: good sound for reasonable money

    Choosing acoustics for a car is far from an easy task, since it requires at least fundamental knowledge of the theory of car audio. In addition, in any case, experience in installing and configuring equipment is needed, because after careless installation, the owner of the acoustics may encounter background noise, low-quality sound and other problems.

    Buying expensive acoustics is not a panacea for future sound problems. Full functioning of speaker systems is only possible if they have been professionally installed. Thus, we can conclude that the correct configuration and installation of the speaker is more important than its cost. In this article we will answer which acoustics to choose and what to look for when purchasing acoustic components.

    Types of columns

    When thinking about which audio system to choose for your car, you first need to understand the types of speakers. All speakers for audio systems are usually divided into two categories - coaxial and component.

    What is a coaxial speaker

    Coaxial speakers are a speaker that is a structure of several speakers that reproduce different frequencies. Depending on the crossover built into the design of this type of speakers, they are usually divided into two-way, three-way, 4..5..6..etc. To find out how many bars there are in coaxial speakers, you just need to count the speakers. We would like to draw your attention to the fact that three bands are enough to reproduce all sound frequencies.

    Acoustics that have 4 or more bands sound very squeaky and are not particularly pleasant to listen to. The advantages of coaxial acoustics include ease of installation and low cost.


    Component speakers

    Component acoustics are speakers of different frequency ranges, which are located separately. These professional speakers are different high quality sound. This is due to the fact that speakers with different frequencies are not located in the same place. Thus, you can get full pleasure from listening to music, since the sound is disassembled into individual components. However, for any pleasure you have to pay: such speakers are an order of magnitude more expensive than coaxial ones, and installing component acoustics requires much more effort.

    Comparison of component and coaxial acoustics

    The quality of sound reproduction, price and ease of installation are not all that distinguish coaxial acoustics from component ones. Another fundamental difference between these two types of speakers is the location of the sound in the car interior. The disadvantages of coaxial speakers include the fact that they make the sound highly directional. The speakers in the front doors are component acoustics. High frequencies, if they are directed at the feet, are very difficult to hear; thanks to the separated components, the tweeters are installed higher, for example, on a car panel and directed towards the listener. Thus, the detail of the sound increases manifold, the music begins to play not from below but from the front, the so-called stage effect appears.

    Diffuser and suspension material

    Any professional description of loudspeakers must contain information about the material from which they were made. The following materials can be used for the manufacture of diffusers: paper, polypropylene, bextren, titanium, magnesium, aluminum and so on.

    The most common are paper diffusers. During their production, sheets of paper are compressed, after which they are given a conical shape. But it is worth saying that, in fact, almost all paper diffusers can be classified as a composite type, since other synthetic materials are used in their production process. Famous manufacturers never disclose what materials are used, because each of them has its own proprietary recipe.

    • The advantages of paper diffusers include detailed sound, which is created due to high-quality internal damping. The main disadvantage of paper diffusers is considered to be their low strength, as a result of which the sound power in the audio system is limited.
    • Diffusers made of polypropylene have a more complex design. They have a neutral sound and excellent impulsive characteristics. At the same time, such diffusers are more resistant to mechanical and atmospheric influences than paper diffusers.
    • Diffusers made of titanium and aluminum began to be made in Germany in the 80s. Their production is based on vacuum deposition technology. Domes made from these materials are different best quality sound: the sound is transparent and clear.

    In conclusion regarding this section, I would like to say that manufacturers have learned to do good acoustics from almost any material, there are even speakers made of precious metals, but they cost a lot of money. We advise you to pay attention to speakers with a paper cone; they have a very decent sound and have been tested by more than one generation.

    It is also necessary to pay attention to what material the outer suspension of the diffuser is made of. The suspension can be made of the same material as the diffuser, and also protrude separate element in the shape of a ring made of rubber, polyurethane or other material. One of the highest quality and most common suspensions is rubber. It must maintain linearity over the range of motion of the loudspeaker system, and also have flexibility as this affects the resonance frequency.

    A subwoofer is the same speaker that is capable of reproducing only low frequencies "".

    Acoustic power and sensitivity

    Many people are interested in how to choose speakers for a car radio, but they do not understand what is meant by such a parameter as power. There is a misconception that the higher the power, the louder the speaker will play. However, in practice it turns out that a speaker with a power of 100 W will play quieter than a speaker with half the power. Thus, we can conclude that power is not an indicator of sound volume, but of the mechanical reliability of the system.

    The volume of the speakers to some extent depends on their power, however, it is not directly related to this parameter. It makes sense to pay attention to the power of an audio system only in cases when it comes to purchasing acoustics for an amplifier. However, in this case, only the rated power (RMS) is important, since other numbers will not provide any useful information the buyer and will only mislead him. But even RMS sometimes has little to do with reality, so it is fair to say that the power indicator is extremely uninformative for potential speakers buyers.

    The size of speaker magnets is also deceptive because high-end audio systems use neodymium magnets. Despite the fact that they are quite unremarkable in appearance, their magnetic properties are slightly higher than those of ferrite magnets. In practice, this means that the sound of the former is much stronger. Due to their miniature size, neodymium magnetic systems also have a shallow seating depth, which simplifies their installation in a car.

    Sensitivity is a parameter of audio systems that shows the intensity of sound pressure. The higher the sensitivity, the louder the sound, but only if the specified power is supplied to the speakers. For example, speakers with low power paired with powerful amplifier can produce more loud sound, than AC with high level sensitivity. The unit for measuring sensitivity is decibel divided by the threshold of hearing (dB/W*m). Sensitivity is affected by parameters such as sound pressure, distance from the source, and signal strength. However, it is worth noting that you do not always need to rely on this parameter because some speaker manufacturers measure sensitivity under non-standard conditions. Ideally, sensitivity should be measured at a distance of no more than one meter when a signal of one watt is applied.

    When choosing a speaker for your car, ask the seller what sensitivity this speaker has? Low sensitivity is 87-88 db; we recommend choosing acoustics that have a sensitivity of 90-93 db.

    Brand

    Another recommendation that can be given to those who are thinking about choosing a specific manufacturer is not to chase a low price and be careful when purchasing speakers from unknown manufacturers. No matter how tempting the sellers’ words may be, you should not pay attention to these tempting offers, since it is always better to turn to manufacturers that have long proven themselves in the market. They have decades of experience in speaker manufacturing, value their reputation, and therefore produce only high-quality products.

    The answer to the question of how to choose acoustics in a car is no longer as simple today as, for example, ten years ago, because there is a large number manufacturers (more than 200). The dominance of Chinese speaker systems significantly complicated the task. Do not completely neglect Chinese products, because with a tight budget, purchasing speaker system from China it won't be so bad decision. But the problem is that there are a large number of unscrupulous sellers on the market who present audio systems made in China as a branded product from American or European manufacturers. In this case, the buyer who decided to spend a couple of hundred rubles will buy “branded” acoustics for $100, when its real price does not exceed $30.

    If we consider this criterion as a specific sound, then for a more natural sound it is recommended to buy European audio systems (Morel, Magnat, Focal, Hertz, LightningAudio, JBL, DLS, BostonAcoustic, this is not the whole list). We also recommend that you refrain from purchasing such companies as (Mystery, supra, Fusion, Sound max, calcel). These manufacturers have a very ridiculous price, but the sound quality of these speakers is appropriate. Speaker systems from Sony, Pioneer, Panasonic, JVS, Kenwood are also very good options, but some of their owners complain about average sound quality. If you are looking for the ideal combination of parameters such as price and quality, then it is best to contact the manufacturers listed above.

    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, the quality of music playback and the price of the speaker system become factors.

    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 a 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 systems playback sound waves Designed for frontal placement (in the front part 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 bulk body. Most often, the third pair of speakers is installed on the central tunnel of the cabin. It makes no sense to install midranges near the rear window; this will worsen 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 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, equipping the system with filters, and correctly 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.

    Advantages various models midbass user reviews consider the package 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 (it must fit tightly 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 various diameters(repeating the speaker configuration), held together with an adhesive connection. 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 bit of 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.

    Properly selected car speakers provide high-quality and beautiful sound of music in the vehicle interior. This article is entirely devoted to the issues of competent purchase of car speakers.

    Now motorists are offered a huge variety of speakers for their “iron horses”. Speakers differ from each other in the quality of sound they provide, technical characteristics, size, cost and a number of other factors. If you are planning to choose the best speakers for your car, first have a clear understanding of the capabilities of the radio installed in the car. Never buy expensive speakers for a car radio that is quite modest in characteristics. Believe me, you will not achieve high-quality sound with such a purchase.

    Audio system built into the car door

    In this case, it would be much more correct to first equip the car good device to play music and only after that choose expensive speakers for it. Car speakers are usually divided into two main categories - coaxial and component. The difference between them is significant. A coaxial system is a set of separate speakers in which several different-frequency devices are assembled to produce sound. Specific number the latter can be different. Automotive coaxial designs can be five-, four-, three- and two-way.

    Regardless of the number of speakers, such systems are much worse in sound quality than component acoustics. In coaxial sets, the entire possible range of music is played by one speaker. Naturally, the effect of such a sound leaves much to be desired. But the price of coaxial systems is quite affordable. It makes sense to mount them in cases where your car has budget radio. In other situations, it is better to choose component acoustics. It has average and woofers located separately from the high-frequency ones. Due to this, component systems are able to produce truly amazing sound - spacious and of very high quality.

    Car speakers come in 16, 10 and 12 cm geometric sizes. In any vehicle, its manufacturer equips special technological holes for connecting speakers. You should focus on their parameters when selecting acoustic elements. It is worth knowing that speakers with a 10–12 cm diameter will in any case sound worse than their 16 cm counterparts. There is only one way out of this situation - modifying the standard holes and mounts for the speakers. It is better to apply for such a service in tech. center. Its specialists are guaranteed to do everything right. And then you can connect 16 cm car audio devices to holes designed for a different diameter.

    Car speakers

    The intensity and quality of the sound produced by the speakers is determined by their sensitivity indicator. Everything is simple here. You need to choose speakers with the highest sensitivity (indicated in decibels). U good speakers this figure cannot be less than 92 decibels. If you are offered car systems with a sensitivity of 82–86 decibels, immediately reject this option. Also pay attention to the resonant frequency of the devices offered to you. Here everything is the other way around. The lower the sensitivity value, the richer and deeper bass the speakers will produce. Experts in the field of car audio advise selecting systems with a frequency in the range of 60–80 Fs.

    Now let's look at the most important thing - the power of the speakers. It is this indicator that worries all drivers without exception who want to choose the right car speakers. It is important to know that there are different types of power: peak, nominal and maximum. The first refers to the amount of power that an audio system can withstand for a long time when playing sound in constant mode. This is, in fact, the main characteristic of the speakers. Maximum power determines the ability of speakers to function for a long time without the appearance of various sound problems (distortion, hissing, wheezing, rattling).

    The maximum power of the speakers should always be greater than the power (output) of the car radio installed in the car. If you don't adhere to this rule, you can't hope for high-quality sound.

    Peak power refers to the ability of speakers to reproduce sound for a short period of time. maximum volume without damaging system elements. If you don't plan to abuse your car speakers and your ears with loud music too often, you don't have to pay close attention to the peak power rating. Let's briefly talk about one more characteristic of speakers - the quality of the sound that they are capable of producing. We will not describe this indicator. Let's just say that the quality factor should be higher than 0.6. This recommendation should be followed primarily by those drivers who plan to install speakers in the doors of their vehicle.

    I think you already have a good idea of ​​what speakers you need to choose for your swallow. In addition to the recommendations above, we will give you some more tips. It is best to purchase car audio devices from official sellers of well-known manufacturers. It is advisable to install speakers at licensed car repair shops and service stations. In this case, the warranty on the speakers remains valid for the entire period specified by the manufacturer of the audio devices. If you install the speakers yourself, oh warranty service you can forget.

    Installing an audio system in a car

    Particular care must be taken when choosing speakers for a car radio, which is combined into one complex with the satellite system that is popular these days. navigation system. This is due to the fact that the speakers in such a situation are connected to the main control panel for the radio and navigation. If sound devices will not meet certain requirements, the entire system will simply fail.

    It is not advisable to equip domestic cars and inexpensive models of foreign vehicles with weak depreciation and poor-quality suspension with expensive audio equipment. During operation, it will quickly fail. Another option is to buy special speakers and radios that are designed to function in adverse conditions. And one last thing. Try to install car speakers or a regular audio system made by the same manufacturer. Then all components of the music playback complex will fit together perfectly. Have a comfortable trip to the songs of your favorite artists!

    X Do you still think that diagnosing a car is difficult?

    If you are reading these lines, it means you have an interest in doing something yourself in the car and really save money, because you already know that:

    • Service stations charge a lot of money for simple computer diagnostics
    • To find out the error you need to go to specialists
    • The services use simple impact wrenches, but you can’t find a good specialist

    And of course you are tired of throwing money down the drain, and constantly driving around the service station is out of the question, then you need a simple CAR SCANNER ROADGID S6 Pro, which connects to any car and via regular smartphone you will always find a problem, pay off CHECK and save a lot!!!

    We ourselves tested this scanner on different cars and he showed excellent results, now we recommend him to EVERYONE! So you don't get caught Chinese fake, we publish here a link to the official website of Autoscanner.

    Owners of modern cars approach the choice of speaker systems with great trepidation. Naturally, almost all cars already have standard system and the average person is generally satisfied with it. However, among car enthusiasts there are true connoisseurs of high-quality, real sound. Therefore, music in the car is increasingly being modernized. This raises the question of what to choose. Component and coaxial acoustics are available on the market. And if latest systems suitable for most, this is not enough for real music lovers.

    Component system: characteristics

    Component acoustics are a set of several speakers designed to reproduce audio frequencies in certain frequency ranges.

    By installing two or three or more such speaker systems, you can cover all frequencies.

    What is a component audio system for?

    Thanks to speakers designed for different frequency ranges, the car audio system gains enormous flexibility in adjustment and configuration when compared with coaxial-type acoustics. By using additional equipment(and these are various electronic processor systems, crossovers, amplifiers), each speaker of a component system can be made to reproduce a specific frequency range.

    Individual volume can also be adjusted. As a result of such manipulations, it is possible to obtain the correct sound stage. Three-component acoustics at correct setting gives very realistic effect presence. The sound is comparable to expensive home theaters. By changing the placement of the speakers and their direction, you can customize the visualization of the sound. 3-component acoustics allow you to expand the sound, remove it at certain frequencies, or bring it closer. This is a big plus.

    Speakers for component speaker systems

    While in a coaxial speaker system for a car two or three bands can be reproduced in one speaker, component acoustics require each frequency range use a separate element.

    The system includes several components:

    • Tweets - designed for playback high frequencies. People call them nothing more than “squeakers”. They are used to voice a range of sounds from 1 kHz and more.
    • Midranges are mid-frequency speaker systems. Their job is to reproduce sound range at frequencies from 150 Hz to 3 kHz.
    • Midbass - speakers designed to reproduce mid and low frequencies. The operating range is from 60 Hz to 3 kHz.

    You can buy and assemble a component speaker system either individually or in the form of ready-made kits from one brand. Assembling an audio system from individual components allows you to select the sound to suit your needs, while the kit has unchanged characteristics. Also, the system must have two devices. These can be frequency dividers or crossovers.

    They must divide the sound stream into separate ranges and send these signals to specific speakers. To put it simply, thanks to crossovers, the device will only voice strictly those frequencies for which it is intended. If 2-component acoustics are used, then the division will look like this. The speaker responsible for midrange/bass will operate within the range of 60-4000 Hz. High frequency element - 4000-20000 Hz. If this is a 3-component acoustic system, then there will be a speaker for mid frequencies, which takes the mid/low range from 1000 to 4000 Hz. Of course, these division options are quite abstract, since each crossover works as the manufacturer intended.

    Characteristics

    Any component audio system has a number of features and special characteristics. You should pay attention to this during the selection process and before purchasing. For example, one of important characteristics- this is the size, or rather the diameter. This parameter very important for the large speaker in the system. This is a midrange/bass element that is mounted in car doors. Here, manufacturers often try to focus on the dimensions of standard places for acoustics on most cars. The most widely available speaker systems are the following. This is 10 cm, component acoustics are 13 cm, 15 and 16 cm. Almost all modern car acoustic components have these diameters. In this case, it is not at all necessary to select the size of the speakers to fit the existing places in the car for their installation.

    When choosing, a parameter such as sensitivity is also important. This parameter of an acoustic system is the ratio of sound pressure to power supplied to the speaker. This is a technical concept that reflects Acoustic efficiency systems. Sensitivity is expressed in the fact that with the same power input, component acoustics (16 cm included), the sensitivity of which is much higher, will produce a stronger sound pressure, that is, it will sound louder.

    For many sound lovers, such a parameter as power is important. Manufacturing companies often indicate on product packaging that the power characteristics produced by component acoustics are different. On the box they write the parameter that the coil on the speaker can withstand - this is the same power input. You should not make any judgments about the speaker system and its power based on these figures. Therefore, you must always look for power ratings. Almost all component car speakers on the market have a power in the range of 60-120 W. The choice depends on many factors.

    Pros and cons of component speaker systems

    The main advantage of such systems is the ability to take advantage of all the advantages that a remote installation provides. If coaxial speakers are mounted at the bottom of the door and all the frequencies they emit go to the feet, then in the case of component speaker systems the car owner has an excellent opportunity to install the elements where they should be. For example, the main speakers are on the bottom, and the tweeters are on top.

    In order for frequencies to be separated, component speaker systems use crossovers, while coaxial systems use only capacitors. The latter can only cut off the lower border tweeter. The crossover can work with more than two frequency boundaries for each individual speaker system. This is a clear and undeniable plus.

    Also, one of the advantages of such systems is the wide range of customization options. To do this, you need a processor-based head unit or external processor. As for the shortcomings, there are two of them. This is the price and complexity of installation. Price - important parameter for most car owners. If you choose 2-component acoustics or a coaxial system, then in most cases it will be coaxial acoustics that will be purchased.

    It's more budget friendly. It is a pity that due to the desire to save money (and this often amounts to several tens of thousands of rubles), most motorists do not get the sound they dreamed of.

    Best choice

    Morel Tempo 6

    This is a two-pole component system with speakers measuring 16 cm. Manufacturer: Israeli brand Morel. The package includes two tweeters and two crossovers. The main ones here are 16 cm component acoustics with a mesh, as well as an installation kit. The set is well assembled and made of good materials. The sound is very detailed at all frequency ranges. The cost of the kit starts from 6330 rubles.

    Focal Performance PS 165

    This, if not the best component acoustics, is definitely very solid, and at the same time affordable. It is ideal for most cars. At reasonable prices, these speakers have a number of advantages. This is amazing sound quality, dynamic and rich in bright colors. The system sounds very balanced. The cost of the set is from 14 thousand rubles. For this price, this is the best component acoustics.

    In this article I will talk about the differences between coaxial speakers and component speakers.

    Coaxial acoustics

    Know that by mounting the tweeter higher on the door panel or dash, you will improve the overall soundstage of your system. Coaxial speakers do not allow this.

    Advice. When placing your tweeters, we recommend first placing them using double-sided tape attached to the back of the tweeter and listening to different places on the doors and dashboard. This will allow you to hear where the tweeter sounds best before committing to the installation location.

    The passive crossovers used in component systems are more complex than those found in coaxial speakers. Most component speakers use a second order (12 dB) or third order (18 dB) crossover. This provides better attenuation of the outer frequencies of the crossover bands, and allows for better integration between the woofer and tweeter. It also improves power management.

    I hope that the article “Coaxial Speakers and Component Speakers” helped at least a little.
