The computer environment has long become more than a tool or a teaching tool. For years, the computer has been around all aspects of our lives, and of course it does not skip the home entertainment center, and the average user spends many hours in front of the computer watching movies, listening to music, or killing virtual enemies.
As an integral part of these activities, most users find themselves in the dilemma of which audio system to buy into a computer. Will it be a system? speakers Which is defined in advance as a system speakers Computer, or maybe turn to another market altogether? Do you choose 2.1, 5.1, or maybe 2.0 at all? What does this system mean 2.1 or 2.0? How do we approach the process of selecting a specific system in our budget? If they are just some of the questions that arise for almost every one of us when he wants to enhance the entertainment experience from the computer.
|Confused? We too!|
In the following pages, we will attempt to address most of the main questions that will arise in this situation, and in particular to give a little background in the field so that readers can understand the concepts that are thrown during a discussion on the subject. For readers who are unfamiliar with the stereo industry, we recommend reading this article "Introduction to Stereo and Home Theater Systems" In order to get acquainted with the field first. Clearly, there will be topics that we will review in this manual, but this time the emphasis will be on systems that are intended forPC, So we will not deal with systems from the dedicated stereo market.
Making order in a mess
The first step that everyone has to go through is deciding what type of systems they need. The choice will be determined according to the requirements of the user from the system. It is often difficult to make this decision, and in most cases the cause is a lack of understanding of the differences between the various systems and how they are suitable for each use. The most common question is: "Do I need a 2.1 or 5.1 system?". In order to answer this question, one must first understand what each of these concepts means, and what is hidden between the lines.
System 2.1, 5.1, 4.1, or any other combination is a short way to tell a few customer speakers There is a system. Many years ago all the systems were stereo systems (and before that they were mono, but we will not go back so far), which according to the numerical system will answer 2.0 systems. Later added to the system speakers And the number grew.
At some stage in the process of evolution was added speaker Which is designed to restore only bass frequencies (and was named subwoofer). Since this speaker can reproduce a relatively narrow frequency band (typically up to a maximum of 200 Hz), decide to separate it from the rest of the speakers and mark it as0.1. Therefore stereo systems added to it speaker This is called an 2.1 system, a surround sound system with five speakers added speaker Such a system is called 5.1, etc.
|Subwoofer - for bass recovery|
Then came the subwoofer
So far everything has been very simple to understand, but then new ideas emerged that every true audiophile tries to deny very much, and soon we will also understand why. Ideas such as: "Now that there is speaker Who knows how to recover bass frequencies, why not transfer the bass from all the speakers to the same subwoofer, and degenerate the rest of the speakers so that they can not recover those frequencies? " PC The average will meet.
Practical speakers Stalists can not reproduce bass frequencies, and therefore,0.1 They should be called 0.9. Unfortunately (or luckily, depending on the approach), they are not described in this way so new users do not realize that in fact speakers Which they are speakers Degenerate from their very planning. Another important point to understand is that in 2.1 systems like this, unlike the 5.1 systems, the subwoofer is not a separate channel that transmits additional content, it transmits the content that is sent to the left and right channel and can not reproduce it.
This is equivalent to ordering an 3 meal when the third packet is no more than a combination of the food that does not go in the first two plates as opposed to another serving. This is also why the connection to systems seems to include 2 lines only and not 3 as you might think.
Stalists say no to Bass
Now that we know what stereo speakers are, we can look at the advantages and disadvantages of these speakers, and what are the alternatives. We will begin with the shortcomings of the stateless speakers, and they are first and foremost their inability to recreate bass, which of course forces them to play in combination with speaker Will compensate for this and will complete the low frequency (subwoofer). The problem is that the sound now comes from different 3 dots rather than just 2 points as in conventional stereo systems. As a result, the ability to reproduce a soundtrack, and the ability to focus and place sounds in the space are impaired.
Another significant disadvantage is the inability to integrate well the sound quality of the stereo speakers with the subwoofer. When using such 2.1 systems, it is usually necessary to adjust the subwoofer power frequently because its combination with the other speakers is not smooth enough and interferes with the sound coming from the system. At the same time, the stereo speakers have advantages, of course, otherwise we would not have encountered them at all. The main advantage of course is their low price resulting from the need for fewer components. In addition, there is a secondary advantage and is the ease in their location due to their small size.
|Stality speaker - no bass reproduction|
There are, of course, alternatives to both systems and systems in the form of systems made up of stand-alone speakers. speakers Shelves are larger and are generally not provided with subwoofer, although there are exceptions.
Loudspeakers will usually not be able to go down to the same frequencies as the subwoofer, but they will be able to recover bass much better speaker Stalletti. Also, in most cases speakers Shelves will produce a more complete and natural sound than speakers Stalates where the sound is cut and transferred to a secondary speaker located elsewhere.
Below we will go over the specification of speaker Characteristically, this will allow us to better understand the differences. Some of you probably resent the lack of mention speakers As we have said, we focus on systems that arePC So we will not deal with them this time.
Before we move on, we want to note one more thing about the subwoofers that are included in most of the 2.1 systems on the market. For a person with a background in stereo systems, the nickname "subwoofer" for those speakers is an exaggeration at best, and a gross and blatant lie at worst. This is because stereo subwoofers are usually speakers Large, heavy, powerful, and able to reproduce very low frequencies.
In contrast, the sub-wafers included in most 2.1 systems and even the 5.1 in the E-PC Can not stand in the same line. Most users will have enough performance, but it is important to know the differences in order to speak the correct terminology, and not to fall into the trap of misleading definition.
