Comparison JBL PartyBox 710 vs JBL PartyBox 110

The total sound power provided by the audio system at maximum volume, in other words, the total power of all the speakers provided by the device (including the subwoofer).

The higher the power, the louder the system will sound and the larger the area it can cover. On the other hand, high power significantly affects the price, dimensions, weight and power consumption of the device. In addition, when evaluating and comparing according to this indicator, it is worth considering some nuances. Firstly, some manufacturers go to the trick and give in the characteristics not the average, but the peak sound power; such numbers can be quite impressive, but they have very little to do with real loudness. So if it seems to you that the claimed power is too high, it's ok to clarify what exactly is meant in this case. Secondly, when comparing, it is worth considering the presence of a subwoofer — it plays an auxiliary role, but it can account for more than half of the total system power. Because of this, for equal total power, a device with a subwoofer may be quieter than a model without a subwoofer: for example, a 2.0 40W system will have 20W per main channel, while a 2.1 40W model may have 20W per subwoofer, and only 10 watts for the main speakers.

The total frequency range reproduced by the acoustics of an audio system. Measured from the lower threshold of the lowest frequency speaker to the upper threshold of the highest frequency: for example, in a 2.1 system with main speakers at 100 – 22000 Hz and a subwoofer at 20 – 150 Hz, the total value will be 20 – 22000 Hz.

In general, the wider the frequency range, the fuller the reproduced sound will be, the less low and high frequencies will be lost due to insufficient acoustic capabilities. On the other hand, do not forget that the actual sound quality also depends on a number of other parameters — primarily the frequency response. In addition, human audible frequencies range from 16 Hz to 22 kHz; deviations from these values are very small, and the upper limit also decreases with age. Therefore, from a practical point of view, it does not make sense to provide too large a frequency range; and impressive performances like 10 – 50000 Hz, found in top-class models, are usually more of a kind of "side effect" of high-quality speakers (and at the same time — a marketing ploy) than a really significant moment.

The phase inverter is a tube installed in the column housing and having an outlet to the surrounding space. The length of the tube is chosen so that a signal comes out of the outlet, inverted in phase relative to the signal from the front of the diffuser. This enhances the sound pressure and improves the sound of the speakers, including at low frequencies. Note that such audio systems should be placed at a certain distance from walls, furniture, etc. — otherwise, a hum may occur due to the movement of air through the phase inverter tube.

A similar function in some models is performed by a passive radiator (see below).

- AirPlay. AirPlay technology was developed by Apple. It is based on Wi-Fi and is used to wirelessly broadcast content from Apple devices to external audio systems. Thus, this function is useful for tech who want to connect an iPhone or iPod touch to the audio system, but do not want to bother with wires; However, it is possible to connect other devices via AirPlay - for example, a PC with iTunes and a Wi-Fi module installed.

- AirPlay 2. The second generation of the AirPlay technology described above, introduced in 2018. Among the main innovations of this version is support for the multiroom format, that is, the simultaneous broadcast of several audio signals to different compatible devices installed in different places. In this way, you can, for example, turn on a radio broadcast of a news program in the living room, relaxing music in the bedroom, etc. In addition, AirPlay 2 received a number of other improvements - improved buffering, the ability to stream to stereo speakers, as well as support for voice control via Siri.

- Chromecast. Original name: Google Cast. Technology for broadcasting content to external devices, developed by Google. Allows you to transmit an audio signal from a PC or mobile device to the audio system; the broadcast is usually carried out via Wi-Fi, while the receiver and the signal source must be on the same Wi-Fi networ...k (with the exception of Chromecast media players). Note that in signal sources (smartphones, tablets, PCs, etc.) Chromecast is implemented at the level of individual applications. For example, at the time of its creation, this feature was available, in particular, in the YouTube and Netflix applications for Android and iOS, as well as in the web versions of these applications for Chrome. Thanks to this format, this technology is extremely widespread these days, and the ability to connect a particular gadget to an audio system with Chromecast is usually limited to the ability to install appropriate applications on this gadget.

- DLNA. DLNA (Digital Living Network Alliance) is a standard that allows you to combine various types of home electronics and household appliances into a single network for content exchange and control. In the case of audio systems, DLNA can be used, for example, to play music from the disk of a computer connected to such a network, broadcast sound to a device installed in another room (for example, an amplifier), etc. Connecting to DLNA can be done either wired or wirelessly (using the Wi-Fi standard), and device compatibility does not depend on their manufacturers - the only condition is compliance with the DLNA standard.

- LAN. Standard interface for wired communication to local computer networks based on the RJ-45 connector. Its presence allows you to use various network functions, such as Internet radio (see "Advanced") or DLNA (see above). Compared to another network interface - Wi-Fi - LAN is less convenient due to the presence of wires, but is more reliable and provides a higher actual data transfer speed.

- Wi-Fi. The presence of a Wi-Fi wireless communication module in the audio system design. This technology is used both in computer networks and for directly connecting various devices to each other; its “range” is sufficient to work within residential premises, even through walls. In this case, Wi-Fi can be used to work with network functions such as Internet radio or DLNA(see above). Moreover, this option is more convenient than a wired LAN due to the absence of actual wires. In addition, support for this technology is a prerequisite for using the AirPlay and Chromecast functions (see above); and in some devices, Wi-Fi even allows you to connect smartphones, tablets and other gadgets as remote controls.

One of the most modern and fastest standards of this wireless communication technology is Wi-Fi 5. The 802.11ac version uses the 5 GHz band (less congested and more noise-resistant than 2.4 GHz), providing speeds of up to 1.69 Gbps per antenna and up to 6.77 Gbps with multiple antennas.

— Bluetooth. Direct wireless communication technology between various devices. One of the most popular ways to use Bluetooth in audio systems is to work with an audio signal, primarily broadcasting sound to wireless headphones or speakers; and some models also provide the ability to connect a smartphone, tablet or other device and use the audio system as an external Bluetooth speaker. However, it is worth considering that initially Bluetooth is noticeably inferior to a wired communication in terms of sound quality; however, in our time, this disadvantage is often compensated by the use of one or another version of the aptX codec(see below).
In addition, other options for using Bluetooth may be provided - for example, exchanging files between the built-in memory and the same smartphone, or remote control via an application. They are not mandatory for modern audio systems, but with the development of technology they are becoming increasingly widespread.

In modern audio systems, the Bluetooth v 5 standard is most often used. Its important innovation is the expansion of the capabilities of the BLE (Bluetooth Low Energy) mode: if necessary, the device can increase the range by reducing the speed, or speed up transmission at the cost of reducing the range. In addition, a number of improvements have been introduced regarding simultaneous work with multiple connected devices.

- aptX support. The audio system supports aptX, a codec designed to improve the quality of sound transmitted via Bluetooth. Accordingly, this function automatically means the presence of a built-in Bluetooth module (see above). The need to use special technologies is due to the fact that in the original Bluetooth format the audio signal is very highly compressed, which significantly affects the final sound quality. The aptX technology is designed to correct the situation: according to the creators, it provides sound purity “comparable to Audio CD (16-bit/44.1kHz)” and almost as good as a wired communication. This is often enough even for comfortable listening to lossless formats, not to mention MP3 and other popular compressed formats. Of course, to use aptX, the signal source must also support it.

- aptX HD support. Audio system support for the aptX HD codec - an improved and updated version of the aptX described above. This version claims sound purity comparable to Hi-Res audio materials (24-bit/48kHz); this allows you to comfortably listen not only to MP3, but also to lossless formats and even uncompressed audio materials. On the other hand, aptX HD support is quite expensive, and its advantages over the original aptX only become noticeable on very high-quality audio materials, for which consumer audio systems are rarely used. Therefore, this function is not particularly widespread.

- A.A.C. A codec used primarily in Apple portable devices to improve sound transmitted via Bluetooth. In this sense, it is similar to aptX (see the corresponding paragraphs), but is noticeably inferior to it in terms of capabilities: if the sound of aptX is compared with Audio CD, then AAC is at the level of an average quality MP3 file. However, for listening to the same MP3s, this is quite enough; the difference becomes noticeable only on more advanced formats.

-LDAC. Sony's proprietary Bluetooth codec. It surpasses even aptX HD in terms of bandwidth and potential sound quality, providing performance at the Hi-Res level of 24-bit/96kHz audio; there is even an opinion that this is the maximum quality that it makes sense to provide in wireless headphones - further improvement will simply be imperceptible to the human ear.

— Network streaming audio. The ability of the audio system to work with network streaming audio services such as Deezer, Spotify, Tidal, etc. Such services are designed to broadcast content (in this case, mainly music) over the Internet; in this case, the played files are not saved in the audio system, but are played directly from the corresponding resource on the World Wide Web. Nowadays, there are many streaming services that differ in the range of music and access conditions; The specific list of supported services should be clarified separately. However, in any case, the main advantages of online streaming include an extensive selection of content and almost instant access to the desired composition; Some services can also work like a radio, automatically selecting music according to the producer's preferences.

- Speakerphone. Possibility of using the device as a hands-free system for a mobile phone. In this mode, the audio system connects to the device, most often using Bluetooth (see above), and the voice of the subscriber on the other end of the line is output not to the phone, but to the speakers of the audio system. This is often more convenient than holding the phone to your ear; In addition, speakerphone is useful if several people need to participate in a conversation.

— NFC chip. NFC is a short-range wireless technology (about 10 cm). In audio systems, NFC is used primarily to facilitate communication via Wi-Fi or Bluetooth (see above). With this chip, you can simply bring an external NFC-compatible device to the audio system and confirm the communication - it's easier than manually adjusting settings.

— Omnidirectional sound. As the name suggests, audio systems with this feature emit sound evenly in all directions, covering a 360° space. Thus, the device can be installed in the center of the room and evenly “fill” it with sound, which will be clearly perceived at any point. On the other hand, an omnidirectional system usually sounds in 1.0 format (mono); the design may include various tricks to ensure surround sound, but such systems still fall short of full-fledged stereo in most cases.

— Voice assistant. Support of the audio system of the voice assistant. The most popular assistants nowadays are:

• Google Assistant
• Apple Siri
• Amazon Alexa

However, other solutions can also be used. In any case, it is worth noting that we are not talking about the function of the audio system itself, but about compatibility with smartphones, tablets and other gadgets that have their own voice assistants. Thus, to use the voice assistant, you will have to connect the audio system to an external device. On the other hand, the capabilities of such assistants are usually more extensive than those of built-in voice control systems (see below); advanced functions are often supported, such as natural speech recognition with complex queries (“Play the latest album of the band ... that I listened to”), voicing the weather forecast, sports results, etc. Of course, the specific set of supported commands and languages may vary - depending on the voice assistant and its version.

— Voice control. A function that is practically mandatory for smart speakers (see “Purpose”) and is almost never found in other types of audio systems. As the name suggests, this control allows you to control the device using voice commands. It differs from the voice assistant (see the corresponding section) in that in this case we are talking about the simplest commands related to the main functionality of the audio system - for example, “Stop”, “Continue”, “Next track”, etc. It is worth keeping in mind that voice control almost certainly supports English, but the ability to recognize other languages should be clarified separately.

— Mobile application. The ability to control the audio system from a smartphone, tablet or other gadget with a special application installed on it. As a rule, the connection is via Wi-Fi (see "Interfaces"). The convenience of this function is not only that the system can be controlled remotely - the application is often more convenient and provides more options than the controls on the radio itself.

— Multiroom support. The device supports Multiroom technology. This technology allows you to create a single wireless network in your home from several speakers placed in different rooms, and simultaneously play music in all of these rooms. The specific features of such networks may be different in different models, they should be clarified separately. So, some devices use a Bluetooth connection, others - via Wi-Fi (directly or via a local network). In some cases, the control speaker broadcasts sound to all the others, and the same music plays throughout the house, in others, the speakers are "equal", and different tracks can be played simultaneously in different rooms. Some audio systems require an external sound source (smartphone, tablet, etc.), others are capable of playing the role of a player themselves, including for streaming Internet services.

— Karaoke.... A popular entertainment that allows users to sing their favorite songs to a backing track (musical accompaniment with the original vocals cut out) — so that the vocals superimposed on the backing track are reproduced through the acoustics of the audio system. This function requires at least one microphone input.

— Karaoke Mix. An extended version of karaoke (see above), providing various additional options — for example, assessment of performance skills in points, singing competitions, etc. As a rule, it allows you to connect two microphones.

— Internet radio. The ability to listen to Internet radio stations on the audio system. In general, such broadcasting is similar to conventional broadcasting, but it is carried out not via radio, but via the World Wide Web, which provides some additional opportunities. Thus, Internet broadcasting has no restrictions on range and range, allows you to listen to programs from any country and in any language; and the list of broadcasters is extremely extensive, among them there are both traditional radio stations duplicating their broadcasts on the Internet, and specific, purely network projects. The presence of this function assumes support for at least one network interface - Wi-Fi or LAN (see "Interfaces").

— Recording to a USB drive. The ability to operate the audio system in recording mode to an external USB device, such as a flash drive. This allows you to record your favorite radio programs from a regular tuner or Internet station (see above), copy music from optical discs, etc.; specific USB recording capabilities depend on the audio system model.

— Clock. A regular clock is a device for displaying time, most often in the form of numbers on a display. Sometimes it is precisely such a clock that turns out to be the most convenient. In addition, this function is necessary for some other features — primarily an alarm clock (see below).

— Alarm clock. A classic alarm clock that gives a signal at a set time. It can be useful not only for waking up, but also in other cases when it is necessary to warn the user about the onset of a certain time. The peculiarity of this function in audio systems is that the signal can be the switching on of a certain radio station or musical composition.

Type of independent power sourceused in the audio system. Such power is usually not the only option — it only complements the ability to work from the network.

— AA batteries. Replaceable elements of a standard size, colloquially known as "finger". Available in a variety of options, varying in quality and price, available not only as disposable batteries, but also as rechargeable batteries; sold almost everywhere. The main advantage of all replaceable cells is the ability to quickly change dead batteries for fresh ones (of course, if there is a reserve), while the original battery has to be charged — and this takes time and an external power source. As for AA, they have a relatively low power and capacity. These characteristics are sufficient for relatively compact devices; however, for models that need to power mechanical drives (for example, for CDs) and/or provide high sound power, “AA” batteries are poorly suited, and therefore are rarely used in them.

— AAA batteries. Replaceable elements, known as "mini-finger" or "little fingers". In general, they are similar to the AAs described above and differ from them only in small sizes and, as a result, less power. Because of this, such power is used only in the most compact models of audio systems, which do not require high power, but small sizes are crucial.

— Batteries C. Replaceable cells known as "Baby". The features of replaceable cells are generally d...escribed in AA Batteries above; here we note that C batteries have a cylindrical shape and are similar in length to “finger-type” batteries, but are much thicker, due to which they are distinguished by higher power and can be used in rather “gluttonous” systems.

— D batteries. Replacement cells, the largest variety of standard cylindrical batteries used in modern audio systems. Used in the most powerful models that require a large amount of energy.

— Batteries. This parameter is indicated in our catalog in two cases: if the device uses standard replaceable elements that do not belong to any of the standard sizes described above, or if the battery size is not indicated in the manufacturer's official data.

— Accumulator. Powered by its own original battery, which is not related to standard sizes, and in some models is also non-removable. On the one hand, this option eliminates the need to constantly buy replacement batteries (or significantly spend money once on rechargeable batteries), moreover, the battery is usually supplied as a kit. However, when the charge is exhausted, in most cases the only option is to charge from an external power source — and this requires not only the presence of such a source, but also a fairly large amount of time.
