Body shape

Case Box. Literally "box". The simplest type of case, in fact, is a box of medium dimensions, designed for installation in the boot.

— Compact. This option means rather than the shape, but the size of the case — as the name implies, it includes devices that have small dimensions. Such subwoofers are as simple as possible to install, some models can be installed directly under the seat. At the same time, their sound quality and power are usually lower than those of full-size ones.

— Tube. The case is in the form of a pipe, on one of the ends of which a speaker is displayed. This form does not significantly affect the sound characteristics, it plays mainly an aesthetic role — subwoofers-pipes look quite stylish.

Rated power

The average (root mean square — RMS) power of the input signal, at which the subwoofer is able to work continuously without negative consequences (damage, failure) for at least an hour. The rated power of the subwoofer must be greater than the power of the amplifier connected to it — in order to avoid overloads.

Max. power

The maximum signal power that the subwoofer is able to withstand for a short time (up to several seconds) without any negative consequences. When selecting an amplifier-subwoofer pair, it is recommended to take a subwoofer with a maximum power of at least twice the maximum power of the amplifier. In general, the higher the maximum power, the more resistant the subwoofer is to overloads.

Frequency range

The range of audio frequencies reproduced by the subwoofer. It is believed that the human ear is capable of perceiving a frequency range of the order of 16 – 20,000 Hz, but in this case note that the subwoofer is designed to reproduce the lower frequency band (up to 200 Hz). Accordingly, in the case of the lower limit of the range, everything is simple: “the lower, the better”; the upper one should not be lower than the lower limit of the main car audio — otherwise there will be "gaps" in the frequencies, which will affect the sound quality.

High voltage input

The presence of a high-voltage input at the active (see "Type") subwoofer. Such an input greatly expands the possibilities for connection. Usually active subwoofers are connected via a linear (low-voltage) input directly to the radio. The high-voltage input allows you to connect the speaker to a separate power amplifier, like a passive subwoofer.

Protective grille

The presence of protective devices in front of the main speaker of the subwoofer — this can be the grill itself, metal rods, plastic elements, etc. Such devices protect the device from foreign objects to a certain extent, and they can also play an aesthetic role.

Material

— MDF. Abbreviation for medium density fiberboard, i.e. medium density fibreboard. This material is inexpensive, easy to process and has a uniform structure, which is important for speaker cabinets. As a result, most modern cabinet subwoofers are made from MDF.

— Resin. It is used in cases where a complex shape is needed, which is difficult to reproduce when using MDF, as well as in compact models (see "Body shape"). In addition, it has no significant advantages over MDF, and therefore is used very rarely.

— Aluminium. Aluminium is light, homogeneous, and also conducts heat well, which allows you to install powerful speakers in such cases without fear of overheating. In addition, it has an elegant appearance. On the other hand, such cases cost accordingly.

— Plastic. Relatively inexpensive and easy to process material, which, at the same time, is available in different grades and may have different properties. Due to this, plastic enclosures are found in both relatively inexpensive and fairly advanced subwoofers; the sound quality of such a subwoofer depends mainly on its general price category.
