Are the front speakers rear or front?

What's the difference between front and rear speakers?

Front speakers are the main component of a home theater.
It is through them that the main sound channels pass, which form the basis of any soundtrack. The remaining channels - rear, subwoofer, center - are, in fact, auxiliary, mixing background noise, speech, and reproducing low frequencies into the main signal. If necessary, you can do without them, but you cannot ignore the signal transmitted by the front speakers. In any system, be it 5.1 or 7.1, the main element is the front speakers, and the rest only add volume and enhance the effect of presence. Are the front speakers rear or front? Front speakers are located in front of the listener in close proximity to the TV or screen as shown in the picture below.

Correct placement of rear acoustics

Before answering the question of the location of the rear speakers, it is worth understanding the question of their variety.
If the area of the room for a home theater or audio system is significant, it is better to prefer dipole rear speakers. They are distinguished by greater uniformity of the sound field. This advantage is achieved by simultaneous sound reproduction in two directions.

Direct radiant rear speakers will be preferable for small rooms with two to four viewers. Their strength is a more focused soundstage in the rear of the room.

Having chosen the appropriate type of speakers, you can begin placing them as rear speakers.

Dipole speakers (for example, Definitive Technology SR9040) are somewhat easier to place. If all the home theater seats are arranged in one row, their center is located directly opposite. If there are two or more rows, the center of the dipole is selected between the rows, approximately 2/3 of the distance between them. Such speakers are placed in ceiling or wall mounting. The latter is preferable; in this case, the height is chosen at the level of the viewer’s ears or slightly higher.

Rear acoustics of direct radiation generate better sound effects. But at the same time it requires a certain distance between the sound source and the viewer. Otherwise, the excessively loud sound of such a speaker will introduce dissonance into the overall perception of the film's sound stage. Therefore, if the size of the room allows, such acoustics are placed under the ceiling away from the viewer.

Choosing a very rare 20cm front speaker or going with 16cm?

The standard space in the front doors is 20 cm. Native Fujitsu coaxial acoustics - paper. But they play very well for the standard acoustics of an average civilian car. C grade highs, good clear midrange, good bass as far as possible for a speaker, I never even thought about subwoofers.

Plus the volume of the door is very large. It is one and a half times longer than a coupe, and wider than that of ordinary civilian cars.

When I listen to 16cm speakers in other cars, they seem somehow castrated to me in terms of drums, beats, voice volume, etc. Well, I’m used to 20cm apparently. Maybe I haven't heard enough good 16 cm acoustics.

I wanted to change the front to something more serious and component-based + add a good 4-channel amplifier.

Questions: 1) There is practically no choice among 2-component acoustics! This is my cross. I've been looking for a long time, maybe you can add something else. Focal Integration IS200 6000 rubles https://caraudio.in.ua/product/focal-integration-is200/ Alpine SPE-20SF 7000 rubles https://www.playauto.ru/product/alpine-spe-20sf/ DLS up8i 14000 rubles - expensive Don't want. There is also Hertz, but the prices are 20 thousand rubles. Previously produced by Blaupunkt, but now they are no longer in the line.

Can anyone tell us about Focal? I understand that hardly anyone has heard of the Focal Integration IS200 - but I’m not familiar with this company at all. And zero reviews due to rarity. Can they do acoustics? And in this price range, can we hope for something normal?

2) Can I hammer it in at 20cm and install it with wooden spacers at 16cm? What do you advise? For a person who listens to English-language rap, industrial, dance music. I'm afraid of one thing - if I put it at 16 cm, I will definitely lose something compared to 20 cm - I will only be disappointed.

Focal 165 AC

This is, as they say, the major league, where critical shortcomings are excluded. Here we have an extremely smart diffuser with a large fiberglass texture and an excellent balance of rigidity and mass. It provides more than adequate midrange detail and excellent bass linearity.

It is also worth noting that a sensitivity of 90 dB is enough to make even the simplest radio tape recorder come to life. The tweeters are adjustable, so there should be no problems with the installation location. Their diffusers are made of aluminum alloy, which could not but affect the sound: the high frequencies are slightly muffled, but this in no way spoils the overall picture, but only makes it even more detailed.

Setting up household amplifiers

The principles of adjusting home amplifiers are practically no different from the method described above. But there is an exception - if it is an amplifier and not a receiver, then it often has two channels and an equalizer.

First, everything is set to zero, and then the desired frequency response is adjusted by ear and taste on the equalizer. They also adjust the input sensitivity so that there is no distortion at the output.

Correct placement of the subwoofer

The placement of acoustics in the room ends with determining the optimal location for placing the subwoofer. This is explained by the significant influence of various factors on the sound of a low-frequency loudspeaker - the location of furniture, the specific material of the reflective planes, the location of the subwoofer and others.

What recommendations should you follow when choosing the correct location for the subwoofer? The key ones are listed below:

It is optimal to choose rectangular-shaped rooms for installing a home theater. In a square room, the subwoofer sounds as poor as possible;
The worst place to install a low-frequency speaker is in the center of the room. As the sub gets closer to the wall, it increases the bass level when the audio system is operating;
Placing the sub in the corner will allow you to get good low-frequency sound, but the resonance effect will also be most pronounced;
It is not advisable to use a subwoofer in a room with concrete walls without additional sound insulation or facing materials. In this case, the “bubbling” effect will be guaranteed. To eliminate it, it is worth using plasterboard sheets, chipboard or other pre-damped enclosing structures.

As you have probably already seen, finding the optimal arrangement of acoustics in a room is a very complex and painstaking process. But its result can exceed all the wildest expectations of the owner. That is why it is worth using the services of professional installers from Hi-Fi Design and solving this problem in the best possible way.

Determining the space for the speakers and their size

In most cases, car manufacturers have already decided everything for the average owner. The design of the case already provides places for installing acoustics. If this is done, it is recommended to take advantage of the auto manufacturer's offers.

In standard places for acoustics, all measures to neutralize vibrations are provided and structural strength is created. The installed speaker will not rattle excessively; it will have enough volume to produce high-quality sound and operate at rated power.

All that remains for the owner of a modern car is to look at the documentation or visually determine which speakers can be installed in the standard compartments. The machine makes it quite easy to get to them, including during wiring.

If the car does not have space for acoustics, it is recommended not to immediately take up a power tool to disassemble the interior and cut holes, but use the experience of other craftsmen. There is enough information on the Internet, on specialized forums, including videos, on how to properly install speakers in a car. When solving this problem, it is necessary not only to obtain good sound and convenient wiring, but also not to compromise the structural strength of the body elements.

Today there are the following standard places for installing speakers:

in the doors, mid-frequency speakers are located here;
in the A-pillars of the roof, in the area of the front glass, to accommodate high-frequency satellites;
in the rear shelf, where high-power speakers with close-to-bass ranges are installed.

Subwoofer placement is considered separately. It may have a design solution that directly indicates its position inside the car body. For example, this could be an acoustic unit for installation in the trunk, on the floor with a flat shape, or as a product for placement under the rear seats.

If one or more elements of the speaker system require their own amplifier for their operation, you need to carefully consider its placement. In this case, it is worth relying on the manufacturer’s recommendations and common sense. The device will need to give off a lot of heat, so it cannot be installed in a confined space.

A subwoofer is an indispensable thing for those who want to get complete pleasure from listening to music. But the trouble is that the power of the radio is not enough for its normal operation. You have to connect an amplifier. And installation is only half the battle. You need to know how to configure the amplifier correctly. We will talk about this and more in our article today.

Installing front speakers

We learned how to make the right choice and acoustic calculation. Now let's move on to the most important thing - how to properly install these speakers in a car?

Podiums

First, let's decide on such mandatory elements as podiums. Not a single serious installation is complete without podiums for midbass, which are located in front. And this applies to almost any car model. If you plan to install, for example, a 3-component front speaker circuit, then everything should look like this:

On podiums in the doors there should be a midbass with a diameter of 16 cm.
In standard places, for example, on a high panel, a midrange with a diameter of 13 cm is placed.
The tweeters are given a place on the A-pillars.

The correct angle of midbass is the main subtlety and complexity of the installation. This must be selected long and hard, often experimentally.

DIY podiums

DIY podiums for front speakers

Installing front speakers always involves choosing a technology for covering a plywood frame. There are currently several ways to do this:

Cover the frame with a knitted T-shirt.
Spray the sheathing with macroflex.
Cover with fiberglass.

It is better to give preference to an intermediate scheme and spray macroflex onto the load-bearing frame and cover it with fiberglass. Tools and materials:

First of all, you need eight-millimeter plywood. About 0.8 square meters of this material will be quite enough. In addition, we find scraps of hardboard and thick cardboard.
We also prepare fiberglass, which should have a thickness of 0.25 mm. You can buy such material at a model aircraft store. About 2 square meters will be enough.
Don't forget to also buy 0.06 fabric, as well as carbon tape.
An important material is epoxy. It is advisable to buy this glue immediately in packages of 150 grams (7 pieces will be enough).
We always buy polyester putty with fiberglass. You need one jar.
We definitely arm ourselves with sandpaper, for which we find a rubber holder that can be bought at any hardware store.
We also prepare a cutter, plasticine, PVA glue, Macroflex, screws and nails.

Preparing the frame

DIY podiums

First, we try on and understand that there can only be one acceptable shape for the bottom of the podium:

From 8 mm plywood we cut out the bottom, a kind of ring for the speaker and side struts.

We assemble the entire structure using nails and PVA glue.
The door pocket can also be used as a standard one. Therefore, you need to unscrew it and file it so that it matches the base of the podium.
Fill the finished structure with Macroflex, always in a thin layer.
After drying, we trim off the excess and shape it using sandpaper.
We putty the surface.

Pasting with fiberglass

As mentioned above, you need to use thick fiberglass fabric. ST will have to be calcined over fire, because it is initially impregnated with paraffin.

Rub the epoxy glue into the foam.
We put ST impregnated with resin. After this, two more layers.
You can also paste over the top with carbon tape, but this is not necessary.

Final stage of work:

An additional backdrop is cut out of hardboard and glued to the plywood with epoxy glue.
Then putty is applied, which must be quickly leveled, otherwise it will harden.
After drying, smooth with sandpaper.
We cover the frame, preferably with vinyl. We use a hair dryer and special glue in the process.

Final installation

Acoustic podiums are ready. Now all that remains is to install them correctly. If the podiums were purchased ready-made, then all the same, you need to read these instructions so as not to make mistakes:

Use a knife to cut a hole in the door trim.
We screw the podiums to the plywood base with self-tapping screws.
It is better to install a lining that must be cut out of plywood in advance. It will then need to be coated with sealant and tightly screwed to the door with self-tapping screws.

It is also advisable to secure the door trim with self-tapping screws, since the pistons do not hold very well.
Installing speakers.

Installing speakers yourself will probably not be particularly difficult. The instructions given here will help you do everything correctly, if you don’t forget to watch the video and photo materials during the process. The price for making podiums for frontal acoustics will not be high, because you only have to pay for consumables.

Nuances of power

When acoustics are made on the basis of passive sound radiators that do not contain built-in amplifiers, then their power is considered by experts to be nominal. Manufacturers indicate Root Mean Square - the root mean square power of the speaker amplifier at which it can operate for as long as desired.

There is Peak Music Power Output - peak musical output power that any acoustics can withstand only for a short time, no more than a second. The main criterion when choosing the power of equipment is the size of the room where it will be installed:

with an area of 17 sq. m. 60-80 W will be enough;
if the room is 20-30 sq. m., then focus on 100 W;
with large, spacious living rooms of more than 40 sq. m., you will need 150-200 W.

All the above calculations are given under the condition of using mono-channel acoustics. When making the final choice of a home theater system, two main parameters must be taken into account: the power of the installation and its sound quality. They have a significant impact on the overall price, but the volume and sound pressure will depend on the power.

For a small room where no more than two people will watch movies, it is quite enough to purchase a system with compact ceiling-type speakers, which is considered by experts to be a more acceptable option when located in limited spaces.

Appearance

The weasel animal weighs up to 800 grams, and its length, including the tail, ranges from 48 to 66 centimeters. It is distinguished by a small head, as well as noticeably shortened legs, between which membranes are poorly developed. The muzzle is pointed, the neck is very flexible, and the ears are pointed.

The beautiful and fluffy tail makes up approximately half the length of the entire animal - from 18 to 21 cm. The fur color is reddish-ocher. In winter, the fur becomes very thick and soft.

The muzzle has a brown tint, which is called a mask. The outline of the lips is clearly visible, as they are highlighted by a white stripe on the muzzle.

The Siberian weasel molts in March-May. Therefore, in the summer, he seems slimmer, since the fur is not so thick and fluffy.

Basic requirements and parameters

System placement rules 5.1 Front acoustic speakers broadcast the main signal from any source - MP3 player, TV or Internet. The modern audio data format is a stereo pair, a two-channel signal intended for playback by a pair of headphones or speaker systems. This is due to the structure of the human body, in particular the hearing aid. Front speakers used for home theater provide stereophonic sound, consisting of two channels - left and right. Small discrepancies between them create a volume effect, a feeling of space. The higher the quality of the acoustics, the more realistic the sound, the less distortion, and the absence of background and spurious overtones. Therefore, the requirements for front systems are much stricter than for other components. To obtain good sound, you need acoustics with a minimum level of distortion and the ability to reproduce a frequency range comparable to the perceptual capabilities of the human ear. To manufacture top-level acoustic systems, special materials and technologies are used, most of which are the manufacturer's secret know-how. An important indicator is the dynamic range, the ratio between the levels of the quietest and loudest signal. The wider it is, the more realistic and natural the sound. Sound quality largely depends on the design of the speaker. To reproduce low frequencies, a large diameter diffuser is needed; as the frequency response increases, the size of the speakers decreases. Modern frontal systems are multi-band, i.e. having several speakers “responsible” for a certain frequency range. The number of front speaker bands determines how many frequency “layers” the sound is divided into. There are simple two-way systems, and there are also multi-way speakers that allow you to finely regulate the frequency palette of the sound.

What are the best 16 cm midrange speakers?

Wideband or midrange speakers are used as budget acoustics. They are easy to install and connect, but the playback quality will be slightly worse than that of coaxial and component systems. Good 16.5 SMS speakers with good bass will ensure normal reproduction of low frequencies even when directly connected to a music center without an amplifier. Among mid-frequency drivers, the top 2022 16 cm speakers in a car are as follows:

Hertz
Swat SP
Morel
Kicx

Hertz loudspeakers are the undisputed leader in playback quality and assembly, but many car enthusiasts prefer Morel speakers. They are distinguished by an extended reproduction range in the direction of high frequencies. Which speakers 16 for a car are best to buy depends on your financial capabilities. The midrange speakers from the list are of approximately the same quality and differ only in price.

What speakers should I put in the front doors?

The main criteria when choosing acoustic systems for passenger car doors are the technical parameters and the manufacturer. In some cases, a coaxial system from a reputable manufacturer will provide higher sound quality than a low-quality multi-component system. Which speakers to install in the front doors depends on their design. Electrodynamic heads of large diameter are usually not used for this purpose. The optimal size of acoustic emitters for installation in doors is 6.5 inches in diameter. This will allow you to get a loud sound for a car interior and good reproduction of low frequencies.

Installing a speaker in a door is not a difficult task, except in cases where the dimensions of the speaker do not allow it to be installed in the seat. The issue is resolved by using a special podium. A component speaker system is often placed in the podium, but the design of the car interior will be slightly disrupted. Often, lovers of good music in the car interior use loudspeakers with a diameter of twenty centimeters or eight inches. Such large car door speakers provide high-quality reproduction of mids and low frequencies, but the dimensions of these speakers are a serious obstacle when installing them in a car door.

Rating of 16 cm speakers for cars

The rating of the best 16 cm speakers for cars is compiled based on technical characteristics and reviews from car enthusiasts about specific models. Car acoustics are evaluated in different categories, since the parameters of a coaxial system differ from wideband and component acoustics. To figure out which 16 cm speakers are best for a car, you need to know their main technical characteristics. These include the following data:

Playable frequency band
Rated power
Peak power
Resonance frequency
Voice coil resistance

When purchasing loudspeakers from unknown manufacturers, you need to know that the technical characteristics may be greatly inflated or indicated incorrectly, so you should always read the reviews of car enthusiasts.

Often car enthusiasts, buying expensive and high-quality emitters, then complain that they cannot obtain high-quality sound. This is usually due to improper installation and fastening of the acoustics, lack of noise suppression, and too much power supplied to the emitter.

The frequency response

The amplitude-frequency characteristic is the dependence of the amplitude of the output signal on the natural frequency of the incoming signal. Ideally, the graph looks like a straight line, but in practice this is impossible, because at different frequencies it has rises and falls.

Our unique hearing aid is capable of perceiving and distinguishing sounds with a frequency of 20 Hz - 20 kHz, however, this is a purely individual feature of each person - with age, the recognition of high frequencies decreases, so older people do not hear everything that is said to them.

The acoustics have a subwoofer that reproduces low frequency sounds of 2-250 Hz. Therefore, speakers are not required to have good amplitude-frequency characteristics at such frequencies, the main thing is that the specified values are not exceeded.

Acoustic amplifier controls

The process of tuning a car amplifier involves changing parameters, each of which has a separate function. To configure even the simplest amplifier there are controls:

So, Crossover Selector is nothing more than a filter switch.
In the LP position, the amplifier operates in LPF (low pass filter) mode.
When the regulator is set to the HP position, the operation is in high-pass filter mode.
In the AP position, the filters are disabled and do not work.

In addition, there is a switch on the rear panel that controls the cutoff frequency of the filters. “Level” is a knob for adjusting the power level. And with the help of “Bass Boost” you can enhance low frequencies, but you shouldn’t try too hard.

If this is a high-power device, then before connecting the amplifier in the car, experts recommend installing a capacitor.

WE CORRECTLY CONNECT ELEMENTS OF THE CAR AUDIO SYSTEM

The simplest connection of car audio systems is to connect the head unit to the speaker set, that is, the built-in amplifier of the device to the front and rear pairs of speakers. But even though there are four outputs, the output will be regular stereo due to the usual duplication of the front speakers by the rear speakers. One of the main conditions when choosing these pairs of speakers is to select them so that the main sound source is still the front speakers, then the sound will be reproduced more realistically. The most significant drawback is sound distortion at higher listening volumes.

To enhance the effect of low frequencies, a subwoofer is added to the systems described above. But connecting it directly to the radio is almost impossible, since the head units have a small built-in amplifier for this purpose. It is because of this that an external, one or two-channel amplifier is purchased for the subwoofer. A good option would be to purchase an active subwoofer. The use of a four-channel amplifier, where a pair of channels go to the front speakers, and the second pair is bridged to a subwoofer, has become very widespread due to its availability and high-quality sound.

In this case, you need to pay attention to the presence of low-frequency filters for the subwoofer and high-frequency filters for the front of the amplifier. If the rear speaker system continues to be relevant, then the number of options for choosing an amplifier is quite large

You can use both two-channel and four-channel. An amplifier with five channels would also be a good option.

To obtain high-quality sound, rear speakers are not always relevant; moreover, better results can be achieved by connecting all four channels to the front speakers, but here you will need a special speaker system, where the inputs for low and high frequencies are separated. Thus, using only the radio amplifier, there is a simple channel-by-channel connection. Such schemes come with active and passive channel division. In the case of passive, you need to choose speaker systems with provision for channel connection, in which, when considering, there are several inputs, and, naturally, two or three outputs. This eliminates the mutual influence of the circuits, and this will certainly improve the sound.

Schemes with active channel division have much more customization options, because the speakers are connected directly to the channel. Then the signal is filtered not in front of the speaker, but before the amplifier amplifies this signal. There are several types of active filtering, these include filters at the amplifier input, or the use of an external active crossover with various adjustments. The most advanced, perhaps, is the use of systems based on digital sound processors.

What is the best power rating for 16 speakers?

This issue has always been controversial among car enthusiasts. Some choose acoustics for maximum power when the sound level in the cabin reaches the pain threshold. Others prefer high and clear reproduction quality. For 16 cm emitters, the normal power is considered to be 45-70 watts. Such power will allow you to provide high-quality sound for the interior of any car. The main thing when choosing acoustics is that its power exceeds the output power of the music center or amplifier. It is desirable that this parameter differ by a factor of two. So, with an amplifier output power of 100 watts per channel, the optimal power of the speaker system should be at least 150-200 watts.

Front acoustics, as the name suggests, are located in front of the listener. In a car it is installed in the doors or front panel (dashboard). It comes in two types. Component, consisting of separate speakers, usually two and coaxial. In it, the speakers are located coaxially - coaxially. Let's figure out where, what types are appropriate to use and how not to make a mistake in choosing.

Let's start with a simple installation. Head plus front.

How to figure out whether to install coaxial or component speakers? Many people believe that component acoustics belong to a higher class. This is wrong. Coaxial speakers come in very decent quality. But they are usually used in high-end home speakers. After all, it is possible to implement in them a circuit of a coherent, that is, more phase-matched sound source. And this is only possible if sounds of all frequencies come from one point. But in real life we are dealing with multi-band acoustics. And in practice, it is possible to combine only a pair of speakers on one axis - high-frequency drivers with mid-frequency drivers. This is what is implemented in products from companies such as KEF and Tannoy.

Why are they rarely used in cars? It's all about the placement of the speakers. What good are perfect speakers if we have to listen to them on our knees? You have to at least place the tweeters in a place convenient for listening.

Therefore, coaxial speakers are usually installed in simple installations with minimal intervention in the car’s design.

So. You have a dilemma. Coaxial or component?

If you are building a system with minimal intervention in the design, there are no seats for tweeters and your budget is limited to 2-3 thousand rubles, you should pay attention to coaxials.

But only two-lane. Don't be fooled by audio jewelry. Why? A separate article is devoted to this. For this money, serious coaxial acoustics are offered. And a good component only starts from this level.

Remember? “Less is better.” Fewer crossovers and individual design elements - better sound. For the same money.

If you have the opportunity to spend more, go ahead and buy components! But what kind? Only with a filter on the tweeter or with a filter on both speakers?

If you do not plan to install a subwoofer, then the main option to choose will be systems with one filter. After all, the mid woofer will work directly, without cutting off low frequencies. This means that the bass will be limited only by the design of the speaker.

I generally prefer these types of designs because of the natural roll-off of the bass. The deeper the bass in the front, the easier it is to make a "front bass" system. Where low frequencies, even those coming from the subwoofer, will be localized in front. (I will touch on the unusual properties of low frequencies in the article about subwoofers)

If there is a sub, then choose any, but only after listening. The opinion that if the front has insufficient bass and this can be corrected with a subwoofer is erroneous. Look only for those speakers that reproduce it. Let's not be so low. But it must be correct and not flawed. Otherwise, you will have to raise the cutoff frequency of the subwoofer, which will lead to greater noticeability. And we need an ensemble. Coordinated, beautiful, and not separate sounds coming from different parts of the car.

Where are the center and rear speakers located?

Depending on a certain distance, there is a special configuration for a home theater around the perimeter of the entire room:

Front part - central channels;
Lateral - frontal;
Rear - rear.

They all make up a surround sound system. The first of them can be placed in two ways: below or above the monitor/TV. Thus, both voices and various sounds are reproduced in excellent quality. Consequently, it appears that all recordings come directly from the image broadcasting equipment. In the set it can be found in the amount of one piece.

It is most often located in front of the TV or behind it. As for the second of those mentioned, this is the configuration of two devices, which I install, as mentioned above, at the rear. Thus, with proper placement, the user can achieve a truly surround sound effect.

Moreover, the distance at which the speakers will be mounted is not even so important: will they stand on the floor, hang on the wall, or be near the ceiling

Where are the front speakers?

First, you should understand the meaning and purpose of the presented model. First of all, this is perhaps one of the main components of the entire home theater. Consequently, with their help, the main sound channels are reproduced. In addition, they determine any structure of the soundtrack.

Types of loudspeaker designs

There are different options for front speakers for home cinema. Let's take a closer look at them: Floor-standing Installed directly on the floor, which makes it possible to optimally adjust or quickly change position if necessary. They usually have an oblong, rather high body, ensuring the approximate location of the speakers at the level of the head of a sitting person. Shelf Mounted on shelves mounted on the wall. It is necessary to ensure that the speakers are not pressed against it, especially if there is a bass reflex at the rear. The height of the shelves should ensure the optimal height of the acoustics relative to the head of the seated listener. Suspended Suspension of speakers allows you to remove interfering wires and acoustically decouple the speakers from the floor or walls of the apartment. In this case, you have to make holes in the ceiling, which may be impossible - for example, a suspended or suspended ceiling gets in the way. There are also wall-hung speaker systems that allow for more precise positioning, but are in close contact with the walls and transmit vibration to them. Built-in This option allows you to somewhat hide the acoustics and make it less prominent in the interior of the room. The problem may arise due to the appearance of excess volume, resonating at its own frequency and distorting the sound. Installation on a solid support To acoustically decouple the speakers from the floor, special massive stands are used to prevent the transfer of vibrations from the cabinet to the floor covering or other materials that distribute sound waves well. It is common to use marble slabs with a thickness of 2 cm or more as stands. It is installed on special spikes that prevent the surface of the slab from touching the floor. The use of such stands eliminates low-frequency distortion, hum and parasitic resonances, the sound becomes cleaner, and the low frequencies become softer. It is not recommended to place speakers directly on marble; you should use spikes or glue rubber feet.

Connection with a high-quality cable

Connecting the front speakers of a home theater should be done with a high-quality speaker cable. It is imperative to observe the phase connection - if on the amplifier the wire is connected to the red contact, then on the speaker it must also be connected to the red one, otherwise you can cause an acoustic short circuit with loss of sound quality. If the speakers have two pairs of terminals for each contact, then you can use the Bi-Wiring connection system, when a double wire goes from the amplifier to each of the contacts. There is also a Bi-amping connection system, when two amplifiers are connected to speakers with two pairs of terminals (one for one pair of terminals, and the other for the second pair). This method allows you to achieve high sound quality and reduce distortion.

How to properly install speakers in the front doors of a car

Installing multiple speakers in a door requires special work. They are difficult to perform at home, so many car owners turn to service centers. They know well how to properly install speakers in the front doors. It is difficult to install component speakers yourself, so contacting a car service center will be justified.

If you need to replace your “original” speaker systems with other models, and remaking the standard seat is impossible or undesirable, then it is recommended to use oval speakers 13 x 18 cm, which reproduce low frequencies well. If you plan to install sound emitters with a diameter of 10 cm, you need to know that they will not provide sufficient reproduction of low frequencies and the car’s speaker system will have to be supplemented with additional bass support.

Which 16 cm speakers are better for the front?

Front speakers are considered the most important part of a car's complex sound system. 16cm speakers without an amplifier will provide the full audio range, but the bass will be slightly weaker, so a low-frequency amplifier will be required for deep and rich bass. However, there are speaker models that are characterized by increased bass response. If we compare acoustic heads by the diameter of the emitter, then there is a direct relationship: the larger the diameter of the emitter, the lower frequencies it can reproduce. Therefore, you need to choose 16 cm models as front speakers. It is difficult to name the best 16 cm speaker, but many positive reviews apply to the CHALENGERPWR 16.2 acoustics.

This is a two-way component acoustic system consisting of two heads and a crossover. The system has a sensitivity of 92 dB and a rated output power of 100 watts. The linear frequency response starts from 40 Hz. These are good speakers 16 in the car and are suitable as a front system.

Dear women! I am a housewife. My son Sergei is in the ranks of the active army. I am already 63 years old, but despite this I gave an application with a request to be sent as a nurse to the hospital. This is what all mothers should do. Everyone must help the Motherland deal with the enemy faster.”

“At a meeting at the Kurma collective farm in the Sharlyk region, where the message about the attack of the German fascist clique on the Soviet Union was discussed, collective farmers proposed to immediately open a nursery in order to be able to work on the collective farm fields and thereby replace the men who had left during the mobilization. The children's shops were opened the next day. All the women went out as one to work, weeding, haymaking and fallow plowing.”

“From the very first day of mobilization, art workers in the city of Chkalov were actively involved in servicing the collection points of the district military registration and enlistment offices. At the House of Folk Art, on the initiative of artists Kudashev, Yanovsky and Stepanov, teams were created to design assembly points and streets of the city. Artists and club propaganda teams perform at recruiting stations.”

“Today there are movies in theaters. At the Theater for Young Spectators: “How the Steel Was Tempered”; at the Oktyabr cinema in the morning and evening: “We are from Kronstadt”, “Lenin in October”; "Hammer": "If there is war tomorrow." The Chkalov regional office is releasing a new defense film “Fighting Enemy Tanks”

“Order on local air defense of the city of Chkalov No. 1. July 3, 1941.

The heads of the anti-aircraft defense forces, districts, sections, and facilities are to put all anti-aircraft defense self-defense groups on full combat readiness. When a threat is declared in the city of Chkalov, completely darken residential buildings, institutions, factories and factories.

"Letter from the Front"

Hello, dear parents! I am writing to you before going into battle. I am healthy, cheerful and believe me, I am very glad that I will finally have to beat the German fascist reptile. Know that I will defend our beloved Motherland and our great freedom-loving people with all my strength and courage. I will beat the enemy the way my dead brother Nikolai beat him. I hope to visit Berlin soon. Be healthy, work calmly, help us with your work, because now the front and rear are one whole. Don't worry about me. The enemy will be defeated. Victory will be ours.

I kiss you warmly, your son Alexander Zhabin"

“We clearly understand what a serious danger looms over our native land. Therefore, we, workers, technicians and engineers of the locomotive-car repair plant, voluntarily join the ranks of the active Red Army. Here in production we worked like Stakhanov. And at the front, in the war against a brutal enemy, we will cherish the honor of our homeland, we will mercilessly defeat the fascists. The enemy will be destroyed.

Group of volunteers: Dmitriev, Dorofeev, Popov, Shakhov, Ryabov, Danilov, Mazurovsky, Agapova and others. Only 35 signatures"

“The housewives of house No. 14 on Sovetskaya Street baked about 20 kg of cookies, bought cigarettes, sweets, sausage, and cheese. They sent all this to the fighters. Students of the Belozersk Secondary School contributed 200 rubles to the construction of the Pioneer tank. Students of grade 6B took an active part in fundraising: pioneer Raya Tsykuleva contributed 10 rubles.”

“We are recruiting teenagers from 16 years of age for training in the professions of mechanic, fitter, turner and welder”

“We will build a tank column named after. Chkalova

In the village of Lopas, collective farmer Yakov Lyubovskoy spoke at a rally: “The German wants to make us his serfs. The bandits miscalculated. Russian people value freedom like a mother values her children. We will spare nothing to strengthen our valiant Red Army. I’ll contribute 200 rubles for the construction of the tank.” In two days, collective farmers of the Mustaevsky district contributed 13,531 rubles in money and 4,360 rubles in bonds.”

Sensitivity

For home theater acoustics, the sensitivity is in the range of 84-102 dB, which means the following: with a signal with a power of 1 W and a frequency of 1 thousand Hz, the system components at a distance of one meter exert exactly this sound pressure. The larger this parameter, the louder the sound at constant power will be significantly higher, but one negative aspect must be taken into account - a rather delicate and sensitive acoustic system can be damaged by a very powerful amplifier; the speakers simply cannot withstand it.

Therefore, when independently selecting all the components of the future cinema, it is necessary to take into account their coordinated and safe operation.

What speakers are best to put in the car?

The main thing when choosing car acoustics is to decide on its type.

The type is determined, in general terms, by a combination of price, quality and dimensions. There are 3 of them. It cannot be said that there is definitely the best and definitely the worst; rather, they have different use cases.

Component
Coaxial
Broadband

Component speakers for the car

Component car speakers offer the best sound quality, but also a fairly high price. Component speaker sets usually consist of several speakers. Or, to paraphrase, several stripes.

Component speaker logic: separate speakers for different frequency ranges. That is, one emitter is responsible for the low frequency, a second for the midrange, and a third for the high frequency. But most often you can find two-way systems on the market.

The most common type - it is also the minimum for building a component system - is a speaker (usually a midrange or midbass, however, these concepts are often synonymous) and a tweeter (“tweeter”). In addition to them, the kit must include a crossover that allows you to adjust the frequency separation.

Component speakers, which is logical, take up quite a lot of space in a car. After all, you need to place several speakers. But it is precisely such a system that, when properly installed and configured, will give the best sound. Ideally, these are not only the front doors and tweeters, but also the rear and subwoofer.

Coaxial car speakers

Coaxial speakers in a car are coaxial emitters installed in one housing. That is, there is a bass (most often mid-bass) speaker, and mid-range or high-frequency emitters are installed directly on it, instead of a cap.

This arrangement of drivers is a great space saver. But the sound quality, with other comparable parameters, will be worse in comparison with component acoustics. The main difference is that coaxial speakers will not give such a natural scene.

All of the above does not mean that coaxial speakers are a bad choice. There are very worthy models that provide excellent sound for the money. For most car audio lovers (those for whom it is not enough to simply listen to the radio from a standard system, but for whom audiophile delights are also alien), this type can be considered the first to be considered.

Best Budget 16cm Speakers

High-quality car audio requires a lot of expense, but even on a modest budget you can build a good quality sound system. One of the best models is JBLGT-652. At a low cost, the acoustics produce clear and well-balanced sound. The lows are well defined and the midrange doesn't blur together, with every tone sounding very distinct. Coaxial speakers with a nominal power of 45 watts and an impedance of 4 ohms have a sensitivity of 93 dB. This group includes Morel Maximo 6 speakers. Unlike JBL, this is a component system consisting of two high-frequency tweeters, two mid-bass speakers, crossovers and mounting hardware.
