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.
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.
Detachable cable
The presence
of detachable cables will save you from possible damage to the device associated with bending the wires. If such an incident occurs, an easy replacement of the wire with a new one allows you to continue using the speakers, and not carry them to a service centre. However, this solution is mainly used in higher-level models, which affects the cost. At the same time, not only audio cables can be removable, for which connectors are provided (according to the classics, this is RCA), but also the power cable.
Lighting effects
The presence
of lighting effects in the design of the speakers. Usually, this is a backlight that can work as colour music — that is, blink and change colour to the beat of the music being played. The main and in fact the only purpose of lighting effects is decorative: colour music gives the speakers a bright and attractive appearance. On the other hand, it does not improve the sound, but it affects the cost.
Wall mount
Possibility
to mount the speakers on the wall. This feature can be very useful if there is no free space on the table or this space needs to be left unoccupied. On the other hand, hanging usually requires drilling walls and installing studs or other fasteners.
Note that with certain tricks, almost any speaker can be hung on the wall — however, it is not a fact that such acoustics will sound normal. Therefore, for wall mounting, it is worth choosing models for which this possibility is directly stated.
Speaker material
A material used to finish speaker cabinets. It is believed that this parameter can significantly affect the characteristics of the sound; however, in fact, the sound quality is determined by so many other factors that against their background this influence is practically not noticeable. In addition, the shortcomings of various materials are easily compensated for by certain technical tricks. Thanks to this, for example,
plastic, which was originally considered a low-cost material, is quite successfully used in premium acoustics. And the main advantage of wood (
MDF) is not so much practical properties as a characteristic appearance. Therefore, the main selection criterion for the material is how much you like the design of the columns.
