Active speakers: features, varieties, selection rules

The presence of a stereo for a modern TV or computer is increasingly needed than a pleasant addition. To date, there is a huge number of diverse music accessories. What acoustic systems are suitable for certain conditions, how to choose them – let’s talk in today’s article.

What is an acoustic system?

This is a device for playing sounds, the last element in the enhanced chain, which includes a sound source, enhancing device and speaker system itself. The design of the device described consists of an acoustic element and emissions built into it (speakers). In the acoustic system there is a device as a crossover. It is necessary to prepare a certain frequency range for each of the columns available in the system.

Peculiarities

Modern speakers can be perfectly approaching any technique that is capable of being a sound source. It can be a simple TV, computer, smartphone or tablet. To date, manufacturers offer a choice of a huge number of different sound systems – from a small portable speaker running on a battery, to professional equipment that is capable of working in multi-channel mode.

The correct speaker system is not just a big set of speakers that are collected in the box and somehow connected to the source. In fact, this is a complex engineering product, in which not only the dimensions of the speakers are calculated, but also the amount of free space in the box, the direction of the audio stream is calculated, the material used in the manufacture and many more factors that ultimately affect the sound quality.

To develop an acoustic system, for calculations and assembly of the design of the engineers.

Of course, you can make a simple system and in the garage conditions from what is, and it will work and reproduce sound. But its task is not only to “deal with silence”, but to play without noise, dresseng, imbalance (unevenness) of speakers, sound distortions and other errors that negatively affect the final quality of sound.

That’s why Premium speakers are more expensive than the same systems, but only medium and economical. The inexperienced man, especially not interested in sound as a sound, of course, will not notice what the good devices differ from the simplest. But if a person who has high-quality acoustics at his disposal, for a large period of time will get used to high-class sound, he will be able to instantly distinguish a high-quality system from cheaper and simple.

What is characteristic of a man with ordinary hearing when using low and middle class acoustics, the difference in sound quality with the class is noted immediately not immediately. And in the opposite direction, the changes are captured instantly.

Advantages

Note the most significant advantages of acoustic systems to simple columns, Communted TVs, laptops and other devices that support external sound instruments:

  • good sound quality even at high volume level;
  • The use of the built-in amplifier facilitates the setting;
  • At a large distance from the columns does not feel loss in power, which makes it possible to successfully apply the AC in large rooms;
  • Active speakers are designed for long-term operation at maximum volume without prejudice to the resource.

Flaws

Despite all the advantages of such equipment, it will even have its drawbacks:

  • In case of failure of an internal amplifier, its repair or replacement will be very difficult;
  • If the system has a multichannel connection, then it is necessary that the connected device has support to support the desired number of sound outputs (otherwise, on such a device it will not be possible to enjoy all the advantages of multichannel mode).

Varieties

To date, there is a huge number of all kinds of acoustic systems. Among them you can find any model that will respond to almost all customer requirements. Some choose portable devices on the battery, which can be taken with you in the evening in the gazebo, in the summer. Others buy stationary options for installation in the room without subsequent transfer somewhere. Third prefer the speakers for their business for the conduct of various holidays.

Then a portable, but powerful technique oriented oriented or for street events.

Consider in order the main distinguishing points that are of the greatest value when choosing.

Location

Outdoor acoustic system has large sizes and considerable weight, therefore it does not have another type of installation. Having an impressive dimensional housing and one-piece overlap under the column itself, it can be said that the work at low frequencies will be stable. Some models of floor systems are installed on special spikes to repay excess vibration at high volume. In others there are raging cameras with sand.

For acoustics of this species, you need to choose rooms with a large area.

There is also shelf acoustics. These are the dynamics of small size, which are installed on special stands and are located at one height from the head of the listener. Systems of this species include columns of the modest size of the front and rear position, satellite, the system with the central canal. This type of systems is designed for rooms less square than for floor systems.

The shelf systems can be attributed to this kind as Built-in devices. The feature of these products is the hidden location in the room. They are placed in such a way that only their decorative lining remains noticeable. They can be mounted in a wall or ceiling, it is important to properly locate relative to the front and rear. Such systems can be used in large and small rooms. The main thing is that their power corresponds to the size of the room.

Acoustic systems having Hinged way fasteners To the vertical surface, fixed by special fasteners and can be used to work the Multi-Room system, as well as as conventional home musical equipment that creates the effect of surround sound. The latter manages to achieve with the help of rear and side speakers. Wall acoustics practically does not occupy a room in the room.

Professional audio system oriented on large rooms and a large number of people. Professional technique multiplying home equipment not only in power and other characteristics, but also by cost. Such equipment is advisable to use in cinemas, on disco, clubs. This technique can support work with Bluetooth and is able to synchronize with the microphone. As a rule, for home, this equipment does not apply, because it is simply inexpedient.

But for concert halls it will be an excellent option. Landscape acoustics is focused on the use of street. To not spoil a beautiful landscape, columns are masked under any items suitable for this. The high cost of equipment is due to the fact that it is resistant to weather phenomena and does not deteriorate due to rain, and in the sun does not acquire white color.

Purpose

Front speakers play the role of basic sound. For this, the dynamics of greater power of the directional type are used. Frontal speakers can work both independently and in conjunction with other types of acoustics. This column is primary for cinemas at home and other stereo.

The central speaker transmits dialogues, music and has the greatest synchronization with the picture on the screen. Subwoofer is used to play low frequencies and has a greater power. It is almost always used in a bundle with the columns of another type, but it does not make sense on themselves. But in aggregate with high-frequency speakers, it provides a “effect of presence”. Subwoofers are divided into 2 types:

  • passive;
  • Active.

The design of the passive includes only a housing and a speaker that depends on the volume of the reproducing device. While his “Active” fellow has its own amplifier with volume adjustment. Thanks to such an adjustment, it demonstrates the best connection with the rest of acoustics.

Rear speakers are installed behind the user – above head or side. They have an appointment in the form of a channel playback from the back side into a stereo with a large number of channels and create an effect of a sound environment. With the correct settings, the rear speakers should not have a difference with frontal speakers. Satellite – This is a small column, which is one of the types of shealing acoustics. It is used in budget models of home theaters.

Number of bands

The band is the subband of all sounds played. Than stripes more, the better the sound. Systems with broadband principle are able to work in all operating ranges. For good playback of many sound frequencies, columns of different types will be required. This will avoid sound distortion. Single-band devices are capable of working with only one frequency range. These are subwoofers and tweeters. A two-band music system can play both low and high frequencies if there are 2 speakers.

Music system for 2.5 bands consists of 2 low-frequency emitters and 1 high-frequency:

  • High frequency speaker reproduces high sounds;
  • one low-frequency operates with low frequencies;
  • And the other – with the average.

The three-band music system is equipped with the speakers of the other high quality frequencies. The number of reproducible channels can reach 5, and in rare cases and more.

Design

Acoustics of a closed design is considered the simplest and has the kind of a sealed body, fully closed. These models have good transitional characteristics, at the expense of which good sound quality is achieved without distortion. But there is also a disadvantage in the form of not very good losing low frequencies.

Phase inverter type speakers belong to the columns of the closed species, but unlike the latter, they have a hole in the inverter output in the design. It is intended for connecting internal and external space. The main task is to ensure sound resonance from the back to the front of the diffuser. Such a resonance creates increased sound pressure in the system.

A similar system has smaller dimensions, if compared with the usual speakers of a closed look. It has a greater sensitivity, which allows you to better play low frequencies.

It is worth noting that the phase inverter has the characteristics of the transition much worse than the closed speakers. This makes it difficult to work with the amplifier and leads to the effect of “blurred sound”.

There is a special musical system with emitter of passive regime. Such equipment refers to phase inverter. A feature of this type of columns is the use of a passive type emitter, instead of a phase inverter, which increases the sound pressure at low frequencies. Passive type emitter works without magnetized devices and coils. The main advantage of acoustics with such a radiator is the maximum no no noise from the movement of air through the pipe.

Consider what Strot acoustics. In its design, a tube is used to send a sound signal through which the mechanical component of the system with the outside is compared. The columns of the described type have a high efficiency, in connection with this, they are used for sound maintenance on large areas.

Tips for choosing

As mentioned earlier, each speaker system is designed for certain operating conditions, more precisely, the premises in which it is. Thus, For large space, the appropriate size and power of the columns is required. Otherwise, listening to music on full volume will not bring the desired result.

While For a small room, there is no point in installing a powerful outdoor system of 5 columns and a subwoofer. Yes, the power will be, but at the same time will begin “distortions”, in which the perception of sound will deteriorate. In such conditions, large columns will not be able to reveal the entire potential laid in them, and the owner will simply overpay for the fact that it cannot be fully.

Choosing speakers, first of all, you need to pay attention to their volume level. The higher this value, the more expensive the kit will cost. When choosing, the material from which the body of the speakers is performed. It is best for this tree – it transmits all fluctuations with minimal distortion.

Acquire an acoustic system best in branded stores with a long-term good reputation and give your preference to a well-known company, which has proven itself in the market in the field of audio systems. If necessary, in professional stores you can provide a certificate for a specific model of columns, which will allow you to avoid buying a fake.

If for some reason you cannot present this document, then the acquisition of acoustics in this store is better to refuse.
