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.

Sensitivity

Sensitivity determines the loudness of the subwoofer when a signal of a certain power is connected to it: with equal signal power and impedance (see below), the subwoofer with the higher sensitivity will sound louder.

Impedance

The electrical resistance of a subwoofer when a signal is applied to it. This parameter is important primarily for selecting a subwoofer-amplifier pair: at a lower impedance than that of the amplifier, the subwoofer will distort the sound, at a higher impedance the sound will be too quiet.

For dual voice coil models (see above), the impedance is specified for one of the voice coils.

Phase control

The ability to change the phase of the sound coming from the subwoofer, in other words, the ability to adjust the sound from the subwoofer to lead or lag relative to the main speakers. This need may be due to the fact that the sound from the main speakers and from the subwoofer can reach the listener with different delays — due to the location of the speakers and the features of the electronics — which negatively affects the sound quality. Adjusting the phases allows you to harmonize this sound. This feature is usually found in active subwoofers.

Subsonic filter

The presence in the subwoofer of an infra-low frequency filter (Finch), also referred to as Subsonic. This filter "cuts" subsonic frequencies, preventing the subwoofer from reproducing them. Often this filter has a frequency control. This feature serves several purposes. Firstly, the human ear is no longer able to recognize such vibrations, and there is no point in reproducing them — this only leads to useless expenditure of energy. Secondly, intense infrasound can adversely affect well-being (both physical and mental). Thirdly, working with infra-low frequencies at high power can damage the subwoofer itself: figuratively speaking, the coil “blows” off the speaker.

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.
