Comparison Divoom Voombox-Party (2 Gen) vs Divoom Voombox-Outdoor (2 Gen)

— Mono. The simplest type of acoustics is a single-channel audio system equipped with one speaker. Of course, there is no question of any volume of sound.

— Stereo. Acoustic system equipped with 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 system of two stereo speakers that create a minimal illusion of "surround" sound, and a subwoofer that provides powerful and rich sound at low and ultra-low frequencies.

A band is a specific part of the frequency range reproduced by an acoustic system. In single-way acoustics, only universal speakers are used that are responsible for the entire operating range. The presence of several bands means the use of specialized speakers, “tailored” to certain frequencies: for example, in two-way speakers, separate high-frequency “tweeters” are most often provided, and in three-way speakers the frequencies are divided into low, medium and high.

For different frequencies, the optimal speaker design will also be different; thus, the multi-band design allows for better sound quality. On the other hand, single-way speakers are lighter, more compact and less expensive. This is exactly what most portable speakers are, since Hi-Fi sound is not alien to them.

The total power of all channels of the speaker system. The higher the power, the larger the size of the room in which the audio system can be used, however, more powerful portable speakers usually have larger dimensions and weight.

The range of audio frequencies reproduced by the audio system. The wider the range, the richer the sound, the more details the speakers can convey, especially in the low and high frequencies. At the same time, we note that the average human ear is able to hear sounds in the range of about 16 – 20,000 Hz, and it makes no sense to provide a wider range in speakers — a person simply will not hear it. Also note that a wide frequency range alone does not guarantee good sound quality.

Theoretically, a higher capacity allows to achieve greater battery life, but in fact, the operating time also depends on the power consumption of acoustics — and it can be very different, depending on the characteristics and design features. So this parameter is secondary, and when choosing it is worth paying attention not so much to the battery capacity, but to the directly claimed operating time (see below).

Operating time of a portable audio system without connecting to an external power source (network or USB port, depending on the capabilities). Note that manufacturers tend to indicate battery life in their specifications under optimal conditions for energy saving: at low volume, without using additional functions, etc. Therefore, in fact, this indicator may be noticeably lower than the claimed one, and speakers with a long operating time will not sound at full volume for the specified hours.

Ability to work portable acoustics in power bank mode. This mode is only found in models with their own batteries (see "Power type"): it allows you to use this battery to power a smartphone or other external gadget. Thus, acoustics can play the role of an additional external battery, which is important in situations where it is not possible to charge a portable device in time.

Note that Power Bank speakers may only be compatible with certain phone models; this point should be clarified before buying.

The main material used in the construction of the hull.

— Plastic. Inexpensive and at the same time very convenient material for portable acoustics. Plastic easily accepts a variety of colours and complex shapes; the latter not only gives space to designers, creating speakers of unusual design, but also allows you to apply various tricks to improve sound quality. In addition, this material is not afraid of moisture. It is believed that the strength of plastic is not very high, but this disadvantage is easily compensated by the large thickness of the material or the use of special impact-resistant grades. Therefore, plastic is found in all categories of speakers, from low-cost to high-end and from "home" to extreme, designed for an active lifestyle and frequent outdoor use.

— Metal. The metal gives the speakers a solid and expensive appearance, and on the practical side, this material is remarkable primarily for its high strength. At the same time, it is much more expensive than plastic — also due to the fact that manufacturers have to use shock-absorbing inserts and other tricks to avoid an unpleasant "metallic" coloration of the sound; and the mentioned strength is most often not critical. Therefore, metal cases are much less common than plastic cases, mainly in rather expensive portable acoustics.

— Silicone. Relatively soft and elastic mate...rial, not afraid of moisture. Suitable for creating dust, moisture and shock-proof speakers; in addition, it is convenient for models with suction cups (see above) — the part of the body that has the appropriate shape can play the role of a suction cup directly. At the same time, silicone has no other noticeable advantages over plastic, so its use is limited to specific models of portable acoustics.

— Rubber. For a number of reasons, rubber is considered well suited for models with dust and water protection, almost all speakers made of this material are protected. In addition, due to the softness of the rubber provides good shockproof properties.

— Wood. Wood is considered the optimal material for speaker cabinets in terms of acoustics. However, the specificity of portable speakers is such that this moment is not decisive in this case, and the main advantage of wooden cases over others (primarily plastic ones) is their aesthetic appearance, with characteristic colours and patterns. In addition, many consider wood a more pleasant to the touch and “natural” material. But this option does not have any special practical advantages, despite the fact that it is quite expensive. As a result, portable speakers with wooden cases are rare — they are mostly designer models created based on the original design.
