Comparison Sven MC-10 vs Sven SPS-701

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.

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.

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.

— 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.

— mini-Jack (3.5 mm). The 3.5 mm jack is used as a standard analog audio output on almost all modern PCs and laptops. Additionally, it's installed in most smartphones, tablets, and portable players, and is quite common in many other types of equipment. In light of this, the mini-jack plug is equipped on most contemporary computer speakers (except perhaps for Bluetooth models). It can be a plug on a non-removable or removable cable, or an adapter from another connector — for example, "2 RCA — mini-jack".

— RCA. The RCA connector, also colloquially known as "tulip," is used here as a line input for receiving an analog audio signal, similar to the 3.5 mm mini-jack. The differences lie in several important aspects. Firstly, RCA operates on the "one connector per channel" principle, and the number of such connectors will depend on the sound format. For instance, stereo acoustics will require a set of two such connectors, a 5.1 system — six, and so on. Secondly, RCA is quite popular in traditional audio equipment but is relatively uncommon among computers. Therefore, in computer acoustics, this input is relatively rare — mainly found in rather advanced models (including solutions with an external amplifier). Moreover, note that in sets with a subwoofer, an RCA connector may also be provided in the main satellite for connecting the "sub," playing the role of an output in this case.

— USB-A.... Sound transmission from a PC, laptop, monitor, or another device is carried out through a standard USB connector of the USB-A format. In this case, the sound is transmitted digitally, reducing the speakers' dependency on the computer's sound card quality.

— USB-C. Sound is transmitted via the USB-C port, through which the speakers receive a digital audio signal from a compatible device. This format is particularly well-suited for modern electronics, where USB-C has already become one of the main connection interfaces. In practice, this makes the speakers more convenient for new laptops, tablets, and other devices without a separate analog output.

— Optical input. A digital input for transmitting high-quality sound, including multichannel. This connection is notable for being completely immune to electrical interference; however, the fiber optic cable is not well-suited to bends and strong pressure.

— Coaxial input. An input for transmitting sound in digital form, allowing for multichannel sound transmission. It uses the RCA connector (known colloquially as "tulip"), though it is incompatible with the RCA interface described above. Unlike optical connections, coaxial connections are susceptible to electromagnetic interference, but they don't require special delicacy in handling the cable.

— Microphone input. An input for connecting an external microphone, located directly on the speakers' body. The purpose of this function is similar to the headphone output described above: connecting a microphone to a speaker placed on the table is often more convenient than connecting it directly to the system unit. Generally, speakers with this feature have an additional plug connected to the sound card's microphone input.

— Subwoofer output. The availability of a connector for connecting a subwoofer allows further enhancement of the system's lower frequency sound. Naturally, the subwoofer is purchased separately, and the output serves as an option to expand the acoustics as needed.

— Headphone output. An output for connecting headphones, located directly on the body of one of the speakers. This connector is particularly convenient when using headphones with a traditional desktop PC: attaching the headphones to a speaker body located on the table is noticeably more convenient than stretching the cord to the system unit. As a rule, the role of this output is played by a standard mini-Jack 3.5 mm socket, which is exactly what most modern headphones (both for computers and general use) are designed for.

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.

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.

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.

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 speaker 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).
