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.
LCD screen
The presence of its own
display in the design of acoustics. Such a display is usually located on the front panel of one of the speakers, subwoofer (if any) or amplifier (if it is made separately). Usually, it is a simple black-and-white screen with segment indicators, however, even such equipment allows you to display a very diverse information and greatly simplifies the work with speakers. Note that the display is most often a sign of a model with extensive additional functionality — usually, it does not make sense to install the screen in speakers with basic capabilities.
Remote control
The type of
remote control that the speakers are equipped with — of course, if such a remote control is provided at all.
—
Wired. The remote control is a separate device connected to the control component of the system (“main” speaker, subwoofer, external amplifier) using a separate wire. Such a remote control is not as mobile as a wireless one, and the wire itself can create some inconvenience. On the other hand, these shortcomings are not always really noticeable: computer speakers are most often located in close proximity to the listener, and he does not have a need for "long-range" control. At the same time, wired remotes are reliable, inexpensive, do not require batteries and work even without being in direct line of sight of the speakers (unlike
wireless ones, which often use IR control). However note that only the most basic functions are usually carried out on such a remote control — such as adjusting the volume and tone.
— Wireless. Wireless remotes most often operate via an infrared channel — similar to remotes for TVs, air conditioners, etc. The main advantages of such control are freedom of movement within at least a few metres from the acoustics. In addition, wireless remotes are often given control over advanced settings. At the same time, there should be no obstacles between the remote control and the receiver (one of the speakers, subwo
...ofer, etc.); and such accessories cost much more than wired remotes.
— Wired and wireless. Acoustic kits equipped with two remote controls at once — wired and wireless. The features of both options are described in detail above, and their combination allows you to choose the remote control depending on what is required at the moment — to have control at hand while sitting at the computer, or to adjust the sound from a distance of several metres, moving around the room. In addition, wired and wireless remotes may differ in terms of functionality. However, it is worth considering that such equipment significantly affects the cost.Volume control
The location of the own volume control provided in the speakers. In modern computer speakers, there are regulators installed in the
front,
back,
side,
top,
on the signal cable, on the amplifier and on the remote control (the latter can be either the only regulator or in addition to the regulator with a different location; see below for details). Here are the features of each option:
— Front. The most popular arrangement nowadays: the front panel of the speaker is the easiest to reach, the regulator can be twisted at any time without any problems, and even if the speakers are tightly surrounded by foreign objects from the back and sides, the front panel usually remains free. Of the shortcomings, one can only note the moment that not everyone likes the extra handles on the front panel of the speaker — however, this is a purely aesthetic nuance that does not affect convenience.
— Behind. The knob mounted on the rear panel of the speaker is not very convenient for frequent volume changes — you usually have to find it by touch, and some free space around the speaker is required to access it. So on such speakers it is most convenient to initially select a certain optimal sound level, and then, if necessary, adjust the volume through the computer's software settings and not reach out to the regul
...ator once again. Therefore, this option is quite rare. On the other hand, such invisibility has its advantages: acoustics acquires the most accurate appearance, without unnecessary small elements on the outside.
— Sideways. A kind of compromise between the two options described above: the regulator is not as noticeable as the front one, and at the same time it is easier to get to it than the rear one. However there should be enough free space on the corresponding side of the column for this, but this drawback is not particularly critical. So the lateral arrangement is found, although less often than the anterior one, but noticeably more often than the posterior one.
— Above. Pretty specific option. In terms of general specifics, it is similar to the side arrangement described above, however, for a number of reasons it is extremely rare — in speakers of non-standard design, as well as in some sets in which the system control is located on the subwoofer (this component is often installed on the floor, and the top position of the regulator is the most convenient).
— On the signal cable. A regulator placed directly on the wire carrying the audio signal. It is used mainly in inexpensive compact speakers: it is easier and cheaper to install a regulator in this way than to build it into a case, and the dimensions of the case itself can be reduced due to the absence of “extra” parts inside.
— On the amplifier. Option for models with external amplifier (see above). It is the parameters of the amplifier that determine the volume of the sound, so it is more logical to place the volume control on it, and not on one of the speakers. Theoretically, the specific location of the regulator can be different; in fact, this knob (like other controls) is usually mounted on the front panel. Note that such equipment is often supplemented by a regulator on the remote control (see below) — the amplifier is not always conveniently located, for frequent adjustments it is more convenient to use the remote control.
— On the remote control. The controller mounted on the remote control — this can be either a wired or wireless accessory (see "Remote control"). Actually, the presence of a remote control is almost guaranteed to mean the presence of a volume control in it, exceptions are extremely rare; and if there are two such consoles (wired and wireless), then the regulators are often installed in both. Also note that volume control from the remote control can be supplemented by a knob located in any of the places described above (except for the signal cable).
