Comparison Dali Zensor 5 set 5.1 vs Monitor Audio Bronze 5

— Outdoor. As the name implies, these speakers are designed for installation on the floor and have a corresponding design: for example, in most models, the cabinet has a large height, selected in such a way that the speakers are at the optimum height when placed on the floor. In addition, floor acoustics are designed with the calculation of the influence of the floor itself on the sound; this allows you to achieve evenness and good depth of low frequencies. Floorstanding speakers in general have the highest power among all types and are usually designed for large rooms.

— Shelf. Shelf speakers are relatively small in size and are designed to be placed on shelves or stands of a different kind, at a significant elevation from the floor (the optimal height is considered to approximately correspond to the location of the listener's head). The advantage of this placement is smooth sound at all frequencies. In addition, such models usually have less power than floor standing ones and are well suited for small spaces — besides, the shelves can be mounted on the wall like a wall speaker.

— Floor / shelf. This type includes multi-channel (see "Intended use") systems in which one part of the speakers is designed for floor installation, the other for shelf installation. The former usually include front an...d, sometimes, rear speakers, as well as a subwoofer, while the latter include a centre channel and low-power rear speakers. See above for floor and shelf installation details.

— Embedded. Speakers designed to mount directly into the ceiling or wall. Often such models do not have a case at all — its role is played by niches in which speakers are installed. According to the shape of the case, namely the mounting hole, such acoustics can be round, oval, rectangular and square. The main advantage of embedded systems is that they take up a minimum of space in the room, moreover, they can be made almost invisible, and in general they are easier to fit into the design than any other type. At the same time, built-in speakers are the most difficult to install, require the participation of a qualified specialist, and it is also very difficult to rearrange an unsuccessfully installed speaker.

— Wall. Such speakers are very similar to bookshelf speakers in a number of characteristics (see above): in particular, they are small in size and power and are designed to be installed at the level of the listener's ears. The key difference is its own mounting system, thanks to which wall-mounted models do not require shelves or other supports and are hung directly on the wall during installation. This led to another difference — acoustic characteristics: they are designed for the fact that there will be a blank wall behind the speaker. Because of this, wall models should not be placed on shelves, even if the design allows it — the sound will be far from optimal. In addition to options with a traditional design, wall acoustics also include the so-called "dipole" speakers: These have 2 speakers facing in different directions and are designed to be mounted on the side wall in premium home theater systems for maximum surround sound.

— Suspended. As the name suggests, speakers of this type are suspended from the ceiling or other base on flexible mounts during installation — these can be either cables or their own cables. Most ceiling models are informational (see "Purpose"); this is due to the fact that one of the easiest ways to block a large room is to install an omnidirectional speaker under the ceiling. At the same time, high-end home systems can also be suspended: the fact is that such placement maximally removes the speaker from shelves, walls, etc., and thus minimizes distortion caused by foreign objects (especially since they are not are always made from acoustically optimal materials).

— Landscape. In addition to an unusual appearance for acoustic systems and stylization for elements of landscape design, this type of acoustics also boasts very stable cases. So, speakers, usually, are not afraid of temperature changes, direct sunlight or precipitation. At the same time, they are designed to play music in open space. They can be freely installed in the yard, many manufacturers initially complete their solutions with a special mounting system to protect the acoustic systems from theft.

— Linear array. A line array is an acoustic system in which several speakers are stacked vertically, directly one above the other. Due to this, such a system generates cylindrical sound waves (rather than spherical, as in classical acoustics). Such waves are distinguished by good “range”, the volume of linear arrays does not decrease as the distance increases as much as that of conventional speakers. This allows you to achieve a uniform and loud sound even in large spaces such as stadiums or concert halls. But at short distances (of the order of several metres), such characteristics are not required. Therefore, the main field of application of line arrays is concert acoustics (see "Purpose").

— Active. Acoustic systems equipped with their own built-in power amplifier. A line-level signal (from the preamp) is sufficient for these speakers, making them extremely easy to use. On the other hand, the built-in amplifier requires power, so these speakers have to be plugged into an outlet as well.

— Passive. Speaker systems that do not have a built-in power amplifier. Accordingly, you need to connect such speakers to an external amplifier (or a device that has such an amplifier — for example, an audio receiver), while paying special attention to component compatibility. On the other hand, passive acoustics are considered more suitable for creating high-end audio systems than active ones: it allows you to choose a power amplifier of your choice, moreover, there are no “extra” electronics in the speaker cabinet, which reduces the likelihood of interference.

— Passive / active. Acoustic systems combining passive main speakers with an active subwoofer. For a number of technical reasons, active subwoofers are more convenient than passive ones: in particular, they save the user from having to look for a specialized low-frequency amplifier, and they provide more tuning options (the latter can be useful for “fitting” sound into a particular room). Therefore, many manufacturers produce passive-active kits.

— 1.0. Single-channel(monophonic) audio system. "Alone" such speakers do not provide a sense of surround sound, but can be used as separate components for multi-channel surround sound systems.

— 2.0. Normal stereo sound: two speakers responsible for the left and right channels. Allows you to create a minimal illusion of "surround" sound by simulating the displacement of the sound source in the space in front of the listener.

— 2.1. A dual speaker system that creates a minimal illusion of "surround" sound, and a subwoofer that delivers powerful and rich sound by adding bass and ultra-low frequencies.

— 3.0. System of three speakers(centre and two front). According to some manufacturers, such systems in small rooms are capable, with some tricks, of reproducing full surround sound without rear speakers.

— 5.0. A set of five speakers(two front, centre and two rear), which allows you to reproduce a full surround sound, which is subjectively perceived by the listener not only in front, but also behind him.

— 5.1. A set of five speakers and a subwoofer for low and ultra-low frequencies, allowing you to reproduce a full surround sound, which is subjectively perceived by the listener not only in front, but also behind him. 5.1 systems ar...e one of the most popular multi-channel audio formats, widely used, in particular, in home theaters.

There are also much rarer options due to narrow needs:

— 1.1. Systems in the form of a subwoofer, on which a general range speaker is installed on top. They are found mainly in concert acoustics — it is convenient to assemble systems for powerful and rich sound from such components.

— 2.2. Further development of the idea embodied in systems 1.1 (see above); in fact, these are sets of two identical speakers of 1.1 format. Such sets are produced from the considerations that for concerts, especially in relatively small rooms, it is often enough just a pair of 1.1 speakers; it is more convenient and often cheaper to buy two such speakers at once than to buy them one at a time.

— 3.1. A system of three speakers (centre and two front), as well as a subwoofer for bass and ultra-low frequencies. It is a "stripped down" version of the 5.1 system; according to some manufacturers, such systems are capable of reproducing full surround sound in the absence of rear speakers, due to which they are perfect for installation in small rooms where it is not possible to place full-fledged 5.1 acoustics.

— 4.0. A variation of 4.1 systems (see below), devoid of a subwoofer, otherwise completely similar.

— 4.1. Simplified version of 5.1 format (see above); such systems usually lack either a centre or one of the rear channels. Anyway, other things being equal, they are cheaper than full-length 5.1, but their sound quality is significantly lower.

— 4.2. This category includes mainly concert acoustics (see "Intended use"), which is an extended version of the 2.2 described above. In 4.2 systems, not one, but two total range speakers are installed above each subwoofer. Thus, you can achieve better and richer sound.

— 5.2. A variation of the 5.1 described above, supplemented by a second subwoofer — this has a positive effect on the quality and accuracy of bass reproduction. On the other hand, setting up such systems is somewhat more complicated.

— 6.1. Extended version of 5.1 format: two front speakers, a centre speaker, three rear speakers (left, right and centre) and a subwoofer for bass and extra bass. It is characterized by a more accurate transmission of surround sound in the rear sector, but is quite rare.

— 7.0. Extended version of multi-channel audio with five main channels (eg 5.1). In this case, the five main channels are supplemented with two more, which allows to achieve a more voluminous and reliable sound. Most often, additional channels are located at the back ("rear right" and "rear left"), but depending on the specific sound format, other installation options are possible — for example, on the sides of the user.

— 8.1. Systems providing 8 main sound channels plus 1 low frequency. The specific distribution of the main channels may be different, depending on the model. However, all 8.1 systems differ, on the one hand, in good reliability of surround sound, on the other hand, in high cost and complexity in setting up.

The number of distinct frequency bands into which the sound is divided when played back through the speakers. For each such band, a separate speaker is provided, and sometimes several (for more details, see "Number of speakers").

Among multi-band consumer-level models, the most common options are 2 or 3 bands — LF / HF and LF / MF / HF, respectively. A larger number, usually, indicates a high class of acoustics, because. it is more accurately capable of reproducing the signal and, accordingly, is more complicated. But there are also small satellites with one speaker ( single-way) for the case of an undemanding listener.

Note that, in addition to integers, models are also produced with a fractional number of bands — for example, 2.5 or 3.5. This marking indicates the presence in the design of a speaker that is responsible for two bands at once: for example, model 2.5 has separate speakers for bass and treble plus a combined bass + midrange (similar in design to bass, but also loaded with mid frequencies).

Speaker sensitivity.

This characteristic is indicated on the basis of how loud the acoustics are capable of producing when a signal of a certain standard power is applied to it. Simply put, the higher the sensitivity of the speaker, the louder it will sound at the same output power of the amplifier. Thus, sensitive acoustics can be effectively used even in combination with relatively low-power "amplifiers". On the other hand, low sensitivity also has its advantages: it allows you to achieve a more uniform frequency response and reduces the likelihood of overloading the amplifier. In the least sensitive modern speakers, this indicator does not exceed 84 dB, in the most sensitive it is 95 – 96 dB or more.

Note that in fact, you have to pay attention to this parameter when acoustics are planned to be used with a separately selected power amplifier. Therefore, for active systems (see "Type"), sensitivity is purely a reference value, and, usually, it can be ignored when choosing.

Impedance is the nominal electrical impedance of a speaker system. Nowadays, a set of standard impedance values are used; the most widely used speakers are 4 ohms, 6 ohms, 8 ohms and 16 ohms.

This parameter is of primary importance for passive acoustics (see "Type"). When connecting such speakers to a power amplifier, it is highly desirable that their impedance matches the speaker impedance for which the amplifier is designed; in case of a mismatch, either overload and distortion in sound (if the speaker impedance is below optimal), or a decrease in power (in the opposite case), are possible.

As for active acoustics, here the impedance is mainly of reference value — the speakers in such systems are initially selected for the corresponding amplifiers. However there is an opinion that a higher resistance reduces the level of interference and has a positive effect on the purity of the sound; however, the difference in impedance between different models is usually not so great that this effect is noticeable against the background of other factors that determine sound quality.

The crossover frequency provided in the speaker design.

A crossover is installed exclusively in a multi-band model (see "Number of Bands"). This is an electronic filter that ensures the division of the incoming audio signal into separate frequency ranges and directs each range to "its" set of speakers. And the crossover frequency shows where the boundary between these ranges lies. If there are more than two bands, there will be several such boundaries: for example, for a four-band system it may be specified "0.15 / 0.8 / 2.8 kHz" or "0.12 / 1 / 3.8".

In most cases, this parameter has mainly a reference value: the frequencies of the built-in crossover are selected to match the operating characteristics of the speakers installed in the speaker system.

The highest power rating of an amplifier that the loudspeakers can handle safely. Too much input power can damage the speakers, so when connecting, make sure that the amplifier's characteristics do not exceed the capabilities of the speakers. It is worth noting that this parameter may be slightly higher than the total nominal power of the acoustics (see below), since in this case we are only talking about the safety of the equipment, and not about the absence of distortion in the sound.

The range of audio frequencies that the front speaker can reproduce. See "Total Frequency Range" below for details on this setting.
