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.

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.

Impedance

The electrical resistance of the speakers to alternating current. This parameter is important primarily for normal compatibility with the amplifier: too low speaker impedance can lead to distortion, overload, and even damage to the speakers, and too high impedance can reduce the sound volume. At the same time, the vast majority of modern computer acoustics have their own amplifiers and are connected via a line input. Therefore, the impedance data is more of a reference value; in fact, this indicator may be needed only when connecting speakers to a “non-native” power amplifier, bypassing the standard one.

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.

Speaker port tube

A phase inverter is a tube of a special design that connects the inner volume of the speaker housing with the outer space. Due to the precisely selected length, such a tube improves the sound of low frequencies, making it more saturated and uniform. The main disadvantage of a phase inverter is that a hum may occur due to the movement of air in the tube; however, manufacturers design speakers in such a way as to minimize the likelihood of this phenomenon.

Note that the presence of a phase inverter is especially useful for subwoofers, but this feature can also be found in general-purpose stereo speakers — for the same reasons.
