Acustic systems or bookshelf speakers – one of the most common categories of goods in consumer electronics stores. They are available in a wide price range. In the store you will find different models: large, small, two-and three-way, two and five-channel, with different buildings, ways of power and connection. And there are also portable audio systems, but this is a big topic for a separate guide.
What to choose for yourself? There are many options, but you need to buy what best suits your intended tasks. With what you need to look at when choosing desktop, floor and wall speakers, we now understand.
Decide What You are Buying Bookshelf Speakers For.
Before buying columns, decide on what purpose it is done. It’s one thing to improve the sound quality when talking on Skype or just creating a musical background. In this case, it is realistic to do with small desktop columns with low cost. And in the most portable version, they do not even need a separate power source – you can choose bookshelf speakers that connect to a sound source (and this is usually a computer or laptop) via USB and receive power from it. In other cases, a fixed network is used for power supply.
If it is a question of not just forming a sound background, but creating a correct and high-quality sound picture, you need to choose stereo speakers 2.0 with a good frequency range and power indicator or look towards the 2.1 format. For those who dream of a realistic sound picture when watching movies or playing computer and console games, speakers in the form factor 5.1 and more are released. It is worth noting that for high-quality music playback is not necessary. A good 2.1 speaker system will do an excellent job with any sound material.
Features of The Choice of Home Speaker System
A common mistake when comparing loud bookshelf speakers is to give an excessive value to the stated range of reproducible frequencies. The technical characteristics of many budget bookshelf speakers indicate the range of reproducible frequencies from 20 Hz to 20 kHz or even more, although a more modest range may be indicated for more expensive acoustics.
By itself, the ability of a speaker to reproduce certain frequencies does not mean anything. It is important how evenly in terms of loudness and with what distortion sounds at different frequencies will be played, compared to the signal that they received at the input. Therefore, if you really want to figure out what frequencies a particular speaker system can reproduce, look for its amplitude-frequency response (AFC) – a graph that shows how correct (quieter or louder compared to the input signal ) These or other frequencies are played.
If you want to clarify what volume a particular speaker system can give, pay attention to the “sensitivity” parameter. It shows what kind of sound pressure (in dB) gives the system from a distance of 1 m with a power supply of 1 watt. A twofold increase in power will give a 3 dB increase in sound pressure. For example, if the acoustics has a sensitivity of 88 dB / W / m, then when summing up the power at 4 W we will get a sound pressure of 94 dB at a distance of 1 m. Some manufacturers indicate sensitivity based on the applied voltage of 2.83 V, rather than 1 W of power. In this case, for comparison, subtract 3 dB from the indicated number.
Finally, it is recommended to listen to selected speakers yourself. Fortunately, listening rooms in specialized stores are not uncommon. If this is not possible, try to find the most detailed overview, telling how exactly this acoustics sound. Even better, it will be a comparison of several models of the same class.
When listening, it is advisable to use equipment that is as close as possible to what is in your home – the same class and preferably the same manufacturer, and it is also important that the audition takes place in a similar room. All bookshelf speakers sound different when using different equipment. Bring to listen to bring with you the music that you usually listen to and know well. This is the only way you can find exactly your columns.
