How to Сhoose Multimedia 5.1 Speakers
Representing the first generation of public worship player iPod, Steve Jobs, head of Apple, announced the release of mp3-players, the company's priorities for the near future. He explained that "sound inherently follows the person wherever he may be: at home, at work, by car or public transport." And indeed, we are the everyday ordinariness do not notice any influence on our sound. Lately things began to change. Buy high-quality sound system sometimes easier than buying a washing machine, therefore, not all that easy.
House for acoustics or acoustics for home?
Most-speaker system is purchased or for connecting to a computer, or to work in a home theater. And in that and in another case in the majority of situations is considered only six channel set as the most versatile. In this review, we consider the most versatile acoustic system capable of delivering high-quality sound.
Thinking about buying a <b>5.1 speakers</b> system is to determine the size of the room in which you will install it. It is important that it was a place not only for large TV or computer, but for all the components of the acoustics: I agree that a room of 10-15 square meters. Not so easy to arrange the six columns. In this case it is better to restrict the system simpler, for example, 2.1.
Pay attention to the possibility of laying the cables so that they do not interfere with a comfortable stay in the room. If for some reason this is not possible, try to look at wireless speakers. Fortunately, in recent years their numbers increased significantly.
In addition to the area, you should definitely pay attention to the acoustic design of the room. It is possible that very expensive speakers for thousands of dollars, calculated on the volume space, will be played at her blankly, while a cheap Chinese system for a couple of hundred dollars will enjoy high quality and rich sound.
Design and Dimensions
Unfortunately, often the design of acoustics and how it fits your home interior is even more important than its technical parameters. This is not entirely correct, because in the current market exuberance can pick up a system that will satisfy not only aesthetically, but also acoustically.
But at the same time, the possibility of acoustic seriously depends on its size. Depending, of course, not straight, but the fact remains: the larger the size of columns, the more they set the dynamics and, consequently, the more powerful they are. This is explained by the physical principle of the sound system: the dynamics of a special membrane, which causes fluctuations in the air. Past and there is sound. Accordingly, the larger the diameter of the membrane, the more air it fluctuates, the more "powerful" issued by its sound. Proceeding from the above, you can draw the following conclusion: the more room in which you want to install the system, the more impressive it should be. Do not forget the fact that the smaller the diameter of the speaker, the worse he plays the bass and the lower its volume.
Sound preferences are important too!
Before buying a multimedia acoustics should clearly present its purpose. What will you do with it? Just watch a DVD or, conversely, only listen to music or even play computer games?
Most speaker systems on the market - are universal, and cope well with both music and video. However, there are more specialized devices for something specific. For example, acoustics, specialized in music, may not have advanced needed for sound of explosions, crashes, etc. Conversely, systems designed for home theater, are often not the best way to cope with high frequencies of classical scores. In short, not to be trapped and enjoy the wealth of home audio space, should give the report itself is why you need a speaker system.
Ease of use
Before you plunge into the technical characteristics of acoustic, do not forget about such important facilities such as a remote control. It would seem, on its availability to speak is meaningless, because the example of TV has all long been understood that control - the good things, but there is still a lot of sound systems (in the long run - cost) that have no remote control. The importance of control lies in the fact that often the main audio system controls are located on the rear, access to which can hardly be called easy. Therefore, the presence of the remote control, albeit wired - necessarily. With his close examination, note the form of buttons, the readability of labels and functional richness. And the menu should be simple so that it could deal with any family member.
Price
Good six-channel multimedia speaker system costs an average of $ 350. Accordingly, the lower limit of our rating was set at $ 300, upper - $ 400.
Technical parameters
The quality of any system, producing a sound, largely depends on the speakers used in its design. Of course, modern sound processing algorithms, high-quality amplifiers, and the entire electrical stuffing a whole, can significantly improve the sound options. However, if the final element - the speaker, very badly, then improve its sound is hardly practicable. Even with the promising technologies. Therefore, regardless of what system you choose - 2.1, 5.1 speakers or even 7.1, you must pay attention not only on its appearance and support of modern technologies for processing sound, but also on parameters that directly characterize the quality of the sound system. The latter, in particular, include: frequency range, output power, signal to noise ratio, and magnetic shielding material of the body.
Frequency - a frequency band that can play the system. If the technical characteristics of multimedia acoustic indicate the values of the criterion of "20 to 20,000 Hz, there is a view of the likely frequency range of the amplifier, not the system itself. For acoustics is often an upper limit of the range goes above 23 000 Hz, but the bottom is most often starts with 50 - 60 Hz: in practice it turns out that the majority of multimedia subwoofers frequency 20-30 Hz, not even reproduce!
Power speaker system, in most cases is characterized by three major standards: DIN, RMS and PMPO. DIN - is the power at which the system can work for a long time with the signal of "pink noise" without physical injury. RMS - the power at which the system can work for one hour with the actual music signal without physical damage. PMPO-power that the dynamics of the system can withstand for 1 -2 seconds on the low-frequency signals without physical damage. In most cases, the manufacturer (as well as the seller), indicates the power of the standard RMS, which, in general, not bad, because it differs from the real (DIN) slightly, by about a quarter. But on the power, as measured by standard PMPO, pay attention should not be, since it is smaller than DIN in about 15-20 times!
Signal to noise ratio - is a dimensionless quantity, which determines the strength of the main signal above background noise and is expressed in the level of sound, the more this index in the acoustic system, the better. For decent speakers threshold ratio is 80 dB and above.
Among the users of the old school there is a perception that the basic material of the sound system should be a tree - and more! However, in practice it is not so simple. For example, if the subwoofer is almost always made of wood (in the budget option, MDF), as important is its resistance to resonance, the requirements for the material remaining columns are not as high. Mandatory condition in the latter case: body column should be stiff, and then he will be able to withstand vibration, will not rattle in the mid and high frequencies and resonate - on low.
