Speakers

The number of individual speakers included in the package. In most cases, here, in fact, the sound format supported by the kit is indicated, and the actual number of speakers also corresponds to it. For example, the 2.0 kit includes a regular pair of stereo speakers (no subwoofer); this is most often considered quite sufficient for listening to music. 2.1 is two main speakers plus a subwoofer, 5.1 is five speakers (centre, front pair, rear pair) and a subwoofer. It is worth noting here that 5.1 is the most advanced format found in modern computer acoustics. It already allows you to achieve the effect of surround sound "from all sides" and at the same time is relatively inexpensive. More extensive sets — 7.1, etc. — should be looked for already in general-purpose acoustics.

A specific case is models in the form of a single column. Usually, they are stereo systems (2.0), made in the format of "soundbars" — two speakers (or two sets of speakers) in one common housing. In some situations, such devices are more convenient than separate speakers; on the other hand, soundbars are more bulky and do not allow you to change the relative position of the speakers, adjusting the sound. Therefore, this option is rare nowadays.

Lines

The number of individual frequency bands played by the speaker. At least one specialized speaker is allocated for each such band.

The point of using multiple frequency bands is that for different frequencies, the optimal design of the speakers will also be different (for example, it is better to make tweeters small, and woofers large). Thus, dividing the sound into bands improves the sound. In turn, the advantage of single-way speakers are compactness and lower cost.

Models for 2(LF / HF) or 3 bands(LF / MF / HF) are considered classic options for multi-band computer speakers. There are also 2.5 acoustics — it has 2 separate speakers for bass and treble plus a combined bass + midrange.

Sensitivity

Sensitivity characterizes the loudness of the speakers when a signal of a certain power is applied to them. The higher this indicator, the higher the volume will be with the same characteristics of the signal source; simply put, on the same computer and the same volume settings, more sensitive speakers will play louder.

In general, an indicator of 85 dB is considered good, 90 dB and above is excellent. On the other hand, computer speakers rarely need a very high volume — they are usually located close to the user and are designed only for him. So in general, this parameter can be ignored.

Signal-to-noise ratio

The ratio of the level of the useful signal (actually reproduced sound) to the level of extraneous noise provided by the speaker amplifier in normal mode.

Any amplifier inevitably creates its own noise; You can't get rid of them, but you can reduce their level. The higher the signal-to-noise ratio, the clearer the sound will be, the less noticeable extraneous interference will be. In modern computer speakers, this figure can vary from 52 – 55 dB (the minimum figure so that the noise does not cause much discomfort) to 90 – 95 dB (comparable to fairly advanced Hi-Fi equipment). However, note that the signal-to-noise ratio is far from the only parameter that affects the sound quality, and its high value does not guarantee a pleasant sound from the speakers.

Frequency range

The range of audio frequencies supported by acoustics. The wider this range — the fuller the reproduced sound, the lower the likelihood that some of these details at low or high frequencies will remain “behind the scenes”. At the same time, the human ear is able to hear frequencies of the order of 16 – 22,000 Hz, and with age, this range narrows even more. In modern audio equipment, especially at the top level, there may be more extensive ranges, but from a practical point of view, this does not make much sense. In addition, it is worth noting that a wide frequency range in itself does not guarantee high-quality sound — a lot also depends on the frequency response.

Speaker output

Total speaker power rating — the sum of the power ratings of all components (front, rear, centre, etc.)

Rated usually means the highest average sound power that the speakers can produce without overloading and damage. Individual peaks of sound can significantly exceed this figure, but it is the average value that is key — in particular, it is it that determines the overall loudness of the acoustics. However it should be borne in mind here that in sets with a subwoofer, the latter can account for about half of the total power of the entire system, while the actual volume is determined mainly by the main speakers. In fact, this means that with equal total power, acoustics with a subwoofer can sound noticeably quieter than a model without a subwoofer: for example, a 2.0 system at 20 W will have 10 W per main channel, while in a 2.1 model at 20 W with 10- watt subwoofer on the main speakers will have only 5 watts.

As for specific values, in the quietest modern PC speakers, the power does not exceed 10 watts. An indicator of 10 – 25 W can be called relatively modest, 25 – 50 W — average, and values of 50 – 100 W and above are found mainly in sets with subwoofers, where a significant part of the power falls on the bass speaker (although there are also ordinary stereo speakers with similar features)....

Theoretically, the power of acoustics also affects its compatibility with a specific amplifier: speakers should not be inferior to it in terms of rated power, otherwise sound distortion and even equipment damage are possible. However, computer acoustics in the vast majority of cases are used with their own amplifiers, optimally matched to the speakers installed in the speakers. So this moment becomes relevant only in some very specific cases — for example, when replacing a complete external amplifier (see below) with another one.

Front

The power rating of each individual front speaker provided in the speaker system. This parameter can be specified for a system with any number of speakers (see above) — all sound formats used in computer acoustics provide a pair of front speakers.

In the most general terms, the higher the power, the louder the speaker is capable of sounding. For more information about this parameter, see "Total power" above. Also note here that for stereo systems without a subwoofer, the power of one front channel is half of the total power; in more advanced acoustics, the power ratio between the channels may be different.

Subwoofer

Rated power of the complete subwoofer of the acoustic system.

Recall that a subwoofer is a specialized speaker for low and ultra-low frequencies; such a speaker is especially useful for games and movies, it is for such content that well-defined bass is most important. Accordingly, the saturation and (to a certain extent) the overall sound quality of low frequencies depends on the power of such a speaker. "Subs" are usually matched to the power of the rest of the system components, however, sets with a similar total power of the main channels may still differ in the characteristics of the subwoofers.

It is also worth noting that the power of this component can be a very significant part of the total power of all acoustics: in some models, about half of the “total watts” (or even more) falls on the subwoofer. This should be taken into account when comparing; see "Total power" for more details.

Functions

Bluetooth. A technology used to wirelessly connect various devices. Allows you to transmit an audio signal, for this purpose it is most often used in computer speakers. This feature is especially convenient when using speakers with equipment that has its own Bluetooth modules — primarily with laptops and monoblocks; it is also possible to connect to compact gadgets like a smartphone or tablet (although it is usually more convenient to use specialized self-powered speakers with such devices). And for computers that do not have Bluetooth, separately connected adapters are available. The range of such a connection is at least several metres; the convenience of the lack of extra wires is obvious. However note that a regular Bluetooth connection compresses the sound quite strongly and may degrade its quality. Therefore, if this moment is critical for you, you should choose speakers with support for one of the aptX options or with a higher Bluetooth version. Each next "generation" has additional features.

Support for aptX. A feature found in Bluetooth speakers (see above). The aptX codec is used to improve the quality of audio transmitted over such a connection; according to the creators, it allows you to achieve quality comparable to Audio CD (16-bit/44.1kHz). Thus, if a regular Bluetooth connection can significantly degrade the sound of even MP3 files with a decent bitrate (not to mention lossless...formats), then when using this codec, the sound quality is often limited not by the properties of the channel, but by the properties of the source file and the acoustics itself . Of course, for aptX to work, it must be supported not only by the speakers, but also by the signal source.

— Support for aptX HD. Support for the aptX HD codec, an updated version of the original aptX (see above). This standard achieves sound clarity comparable to Hi-Res (24-bit/48kHz) audio. On the other hand, its support is more expensive; and the differences from the original aptX only become noticeable on very high-quality audio materials, for which computer speakers are rarely used. Therefore, this function has not received much distribution.

NFC. Technically, NFC is a universal wireless technology with a range of up to 10 cm, which allows to achieve a very wide range of applications. However, in computer speakers, this technology is mainly used to speed up Bluetooth connection (see above): it is enough to bring another NFC device (for example, a smartphone) to the speaker chip — and the chips will “recognize” each other and automatically set up the connection, the user will only have to confirm his.

— USB A. USB port, which allows you to connect external peripheral devices to the speakers — primarily drives like "flash drives". Most often, such a connection is used to play music from external drives — in other words, the presence of USB A turns the speakers into a standalone music centre. Often, it is also possible to charge portable gadgets (for example, smartphones) from this port. On the other hand, note that speakers with this feature are noticeably more expensive than similar models without USB, and they may be inferior in sound quality due to the presence of additional electronics that can interfere.

Card Reader. Own device for reading memory cards, most often the SD standard. Speakers with a card reader can work like a stand-alone music centre: music from a memory card can be played even without a computer. At the same time, the card reader itself is used only by speakers; the ability to read a memory card by a computer is usually not provided in such models. It is also worth bearing in mind that the memory card slot and the electronics that “serve” it are a potential source of interference, so speakers with this function may be inferior in sound quality to counterparts without a card reader (at a higher cost).

FM receiver. The presence of a built-in FM tuner allows you to use the speaker system as a radio receiver — to receive and play FM radio broadcasts. It should be noted that for reliable reception, most likely, an external antenna will be required; a cable for connecting it is sometimes included, but the antenna itself must be purchased separately.

Treble adjustment. The ability to separately change the volume of high frequencies. In fact, it is the most simplified version of the equalizer: it allows you to adjust the overall colour of the sound by changing the HF level relative to the rest of the frequency spectrum. Most often used in combination with bass control (see below), but can also be provided as the only frequency control.

Bass adjustment. The ability to separately change the volume of high frequencies. Similar to the treble control described above, used to adjust the overall tone of the sound. At the same time, quite a few models with this function have only a LF control (without a HF control). But do not confuse this function with subwoofer level control. In this case, it is precisely the adjustment of the lower frequencies of the entire system that is implied.
