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.

Based on the sound quality when selecting a signal from the standard car radio of 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 stock radios are 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 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 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, 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 possibility of detailed customization, 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 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.

Every car owner countless times faces a difficult choice: save on car equipment or buy the best, punching a hole in the budget. When it comes to car audio, coaxial and component systems can force a lot of balancing, studying the advantages and disadvantages of both and weighing preferences. But you can take a serious choice only when the names are not a set of letters, but terms that speak volumes. So, coaxial and component car acoustics: what they are used with and what they hear from them.

Definition

Coaxial car speaker system is a single design of speakers: high-frequency ones are also located on the axis with the low-frequency one. There are two-way and three-way, and this separation is carried out through a crossover built into the design.

Component speaker system represents different-frequency speakers, spaced separately.

Comparison

The fundamental difference between coaxial and component acoustics is the location of the sound source in the space of the car interior. The single design of coaxial systems makes the sound highly directional, so such speakers are often installed as an addition - in the rear seat area, for example, while a component system operates at the front. The latter scatters the sound source throughout the cabin - we get a kind of super-surround at the output, but there is a catch: each high-frequency, low-frequency and mid-frequency speaker reproduces sound from its own “point”, so the acoustic picture is very heterogeneous. However, combining speakers in a coaxial cable creates the effect of mixing frequencies, causing the sound to lose purity. For small cars, component acoustics are not suitable, since in a limited space there will be no difference from coaxial ones.

Philips component speakers

In addition to the dispersion of the speakers, the purely technical difference between a coaxial and a component system lies in the crossover, which acts as a frequency filter. In coaxial systems it is built-in (with the exception of some models of the hi-end segment), in component systems it is external.

Another key point when comparing coaxial and component speakers is the installation method. What is in the car “from the factory” is most often called an acoustic system at a stretch. Both the coaxial and component systems in the car interior are the work, if not the hands, then the expenses of the car owner. To install the first one, no special knowledge or technology is required, and this is most often done independently. The component system involves installing speakers in accordance with the correct acoustic zones, equipping shelves and applying sound insulation. In addition, a lot depends on the radio: the lower the level of technology, the more useless it is to fuss with component systems that simply cannot provide high-quality sound. However, if you are not an avid music lover, and on the road you are accompanied by simple chanson or disco of the 90s, or even the radio, the component system will be an unnecessary burden, and again, you simply will not feel the difference from the coaxial one.

The deciding factor for many car owners may be the cost of the acoustics itself, not to mention the cost of paying for its technical support. This category of comparison is accessible to everyone and is arithmetically simple: coaxial systems are usually cheaper than component ones. The only exception is transformer systems that convert component ones into coaxial ones using special fasteners.

Conclusions website

2. Coaxial systems produce highly directional sound.
3. The crossover (frequency filter) is built-in in coaxial systems, external in component systems.
4. The component system is more difficult to install and requires compliance with a number of conditions.
5. Coaxial acoustics are cheaper than component ones.

Car audio system: features of choice.

For many drivers, music in the car is sacred. First of all, the sound quality depends on the radio itself. Poor sound output cannot be turned into high-quality stereo with any speakers.

If you prefer just the background noise of the radio on the road, standard factory speakers are quite sufficient for a regular car radio. Such audio systems do not require additional financial investments and are a good solution for small economy class cars.

If you are more demanding of sound quality, have chosen a high-quality radio and are thinking about choosing speakers, pay attention to the differences between coaxial and component audio systems.

Coaxial speakers are a single design with a built-in crossover, capable of reproducing sounds of different frequencies using multiple speakers. Most often, the speakers in coaxial speakers are two-way, this is enough for high-quality and clear sound. An audio system with more than 3 bands, as a rule, should not be taken seriously, and this is pure marketing; not a single serious manufacturer, even in acoustics for $ 1000, will make more than 2 bands.

The positive aspects of a coaxial sound system are its low cost and ease of installation (most often on a special panel behind the rear seats). For a small salon, coaxial audio systems are the best solution, because... There is no point in spending more, it will not significantly affect the sound quality. Such speakers will not create a surround stereo effect, making the sound more narrowly focused.

Component audio systems are distinguished by the fact that their speakers are located separately, providing the highest quality surround sound by dividing frequencies into components. In component acoustics, each speaker is autonomous and the intersection of frequencies is completely eliminated, and therefore the sound is cleaner and more professional, even true music lovers will appreciate it.

Guarantees higher quality sound and a crossover specially built into component audio systems. By installing the speakers in a special way (high frequencies lower, tweeters higher), you can even achieve the effect of “stage sound” aimed at the listener.

The only inconvenience when purchasing component audio systems is their high price and the need for professional configuration and installation. It is almost impossible to do this correctly without special skills.

When choosing coaxial or component audio systems, be sure to pay attention to the manufacturer. It is better to give preference to trusted brands than to entrust the sound in your car to Chinese fakes that promise high quality at a low price.

It is a mistake to believe that the volume of audio systems depends on the power level of the speakers. This parameter is important only when purchasing acoustics for an amplifier and is not at all informative for the average user.

It is better to ask the seller what sensitivity certain coaxial or component speakers have, and independently evaluate the sound quality (manufacturers may not always provide accurate information in the instructions).

Before installing any audio system, for the highest quality sound, take care of soundproofing the interior, because engine noise and highway sounds distort the purity of perception. A special material is glued to the floor and roof of the car, and is also placed in the space between the passenger compartment and the hood.

You should also take a responsible approach to choosing a subwoofer for your car. Not only the volume of the cabin and the genres of any driver’s music are taken into account, but also the personal requirements for sound quality. Active subwoofers are the most popular; they are easier to install.

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 includes 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.

Finally

So, to summarize: to select a component speaker system, you should decide on the size - this significantly affects the installation. Models with low cost and at the same time simple design are popular. 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.

Wideband speakers are acoustic systems in which an electrical signal is supplied to the speaker without first being divided into frequency bands - low-frequency and high-frequency. At the very beginning of the era of sound reproduction, almost all speakers had high sensitivity and were full-range. As sound reproduction technology developed, the design of speakers with one speaker responsible for the entire sound spectrum was replaced by a system in which the sound was divided into two bands by a special device - a crossover. In such speakers, individual speakers of different designs, made of different materials and different weight-dimensions “served” their individual sub-range. The lower speaker with a larger area and density of the diffuser was responsible for low frequencies and mids, and the upper one for high frequencies. As acoustic systems developed, the fragmentation of sound into bands continued, and speakers with three, four and even five sound bands began to appear - they began to be called. If you follow the definition exactly, then broadband speakers in their pure form are found these days only in “radio points”, but marketing has made its own adjustments, and today the definition includes many speakers that in the strict sense are not broadband - they are TWO-WAY. The signal is divided into two bands by a crossover and fed to two speakers of different designs - the upper speaker is responsible for the high frequencies, the lower one for the low frequencies and midranges. At the same time, there are other speaker systems that also have two bands and two speakers, but no one calls them broadband. Where is the truth?

In order not to confuse readers, it seems to me that it is necessary to give a modern definition of “broadband acoustics” from the marketing side, not the technical side. Moreover, from the technical side it is already given at the beginning of the article.

A wideband speaker system today is usually a floor-standing or large bookshelf speaker with no more than two high-sensitivity speakers. The speaker responsible for the bass and midrange is equipped with a light, thin diffuser of a large area, most often made of paper. It is responsible for reproducing most of the sound spectrum of music - from drums to vocals. The speakers responsible for high frequencies also have a significant area - they are smaller than low-frequency ones, but you won’t see any “tweeters” with a metal diffuser the size of a nickel in wideband speaker systems.

Lightweight diffusers of wideband speakers are capable of transmitting the finest nuances of music - vocal overtones, the lightest string plucks. When you listen to broadband acoustics with a good reproducing path, it seems that you can hear rosin falling off the violinist’s bow. Wideband acoustics are ideal for reproducing classical and light live music, and for this they are deservedly loved by many audiophiles. The best full-range speakers I've ever heard were based on LOUTHER speakers. You can listen and order them

Acoustic systems UNIVERSO VIRTUOSO by Alexander Chervyakov (www.tube-eden.ru) - classic broadband acoustics. However, at first glance it is clear that these are still two-way speakers.
______________________________________________________________

Alexander himself will tell you more about these acoustic systems:

"Long ago I was lucky enough to hear the correct "open baffle"
in English) acoustics on the right speakers in the right room. I remembered this sound for the rest of my life. It is impossible to imagine anything more natural, light, musical. There is no shamanism or isotericism here - the speakers simply work without experiencing any pressure from the rear side on the diffuser and, as a result, we have such an open, light and airy sound. Because the speaker also emits sound from the other side, creating additional volume and conveying the atmosphere of a studio or concert hall very well,
additional overtones appear, cat. impossible to hear in any other arrangement. Unfortunately, in this life you have to pay for everything. It’s not for nothing that I mentioned the word “correct” three times. To get more or less decent low frequencies, the speaker must be at least 12" and the shield very large. But most importantly, the room must also be large! You cannot place such acoustics close to the walls. Min. 2-3 meters from the walls. This completely kills this idea in our realities. True,
There are “enthusiasts” who are not burdened by either experience or knowledge, and they install the first speakers they come across in shields, like “door” and pruzza. Let's leave this happiness to them, and we ourselves will go a different way...

Concept.
1. Because my favorite and, in my opinion, the best amplifier has a max. power only 2W, total. acoustic sensitivity should not be
less than 95-96dB/W. This will make it possible to comfortably listen to music at only 0.5W of power in a room of 20-30m2.
2. Acoustics should sound in rooms of any reasonable size (15-60m2).
3. Mid and high frequencies should be played by one wide-range speaker in an “open baffle” design. The speaker should be very musical and balanced.
4. The ShP section must move freely in all directions to select the optimal position.
5. A separate section should be responsible for LF. Mandatory at least 12". An ideal “stitching” between the bass and the squelch is required. The filter must be the simplest of the 1st order. The crossover frequency must be in the range of 100-200 Hz. This is only possible with the correct and successful choice of the bass speaker. The speaker must be sensitive not less than 96-97 dB/W.
6. Possibility of quick adjustment of the level between bass and noise for personal and genre preferences.
7. Unusual design and finishing. Do not use varnishes that give the appearance of a cheap laminate to natural veneer. Give preference to waxes and oils. Possible vintage look.

Design.

Everything listed in the concept was implemented in the final design. The most difficult, expensive and tedious thing was choosing a woofer. Modern industry has completely switched to producing dull, heavy, long-throw, low-sensitivity woofers with a dull sound. The wideband speaker is very fast and light, and it seemed impossible to me to find the same bass. But the miracle still happened. I managed to find a very fast and light one with a small stroke, a paper one with a fabric suspension, cat. keeps up with ShP. It is important that it does not have the gigantic “overshoot” that is usual for low-frequency speakers at the end of its operating range, so it turned out to be possible to “cut it off” with a simple filter on one coil. Speaker 12"(30cm),
American Eminence. Body volume 150 l, bass reflex design.
ShP - Audio Nirvana, 6.5", also USA. Very musical and balanced. The filter for it is the simplest 1st order on a Solen film capacitor. “Purists” can easily abandon it by removing the phase mismatch by correct placement of the ShP section on the body
LF. ShP has a level regulator. The idea is this: you want to hit the gas on a rock or
electronics - strangle the ShP and add power with an amplifier. Two correct ones will blow you off your chair.
12" woofer in the right low-frequency design. The bass drum will please you.
Finish: veneer, waxed. Any veneer is possible. In my case, oak.

Sound.
It's pointless to describe it. We must listen. The sound is unusual. Has nothing in common with modern branded acoustics at any price. I don't know any analogues. The consistency and balance is perfect. The sound is completely disconnected from the speakers - they simply do not exist. Just music and you. The musicians have come to visit you and are playing for you. As always with me, it sounds in rooms of all sizes. Preferably, of course, more. This is not related to childhood and stupid diseases of ugly modern systems, such as muttering at low frequencies. Nothing ever hums or hums for me. Simply, a priori, greater acoustics are better revealed in large rooms. If you have 20m2, it’s already normal, 30m2 is good, 40m2 or more is great.

Genre preferences.

If you listen mostly to rock, you should probably give it a pass. In principle, sometimes you can have a blast with a powerful two-stroke or transistor, but no more. If your preferences are jazz, vocals, classical, blues, you are welcome.
