Size

The size (diameter) of the main subwoofer speaker. In all types of subwoofers, this parameter primarily affects the power and depth of sound: the larger the speaker, the louder it is and the deeper the bass it can provide (ceteris paribus). However with an increase in the size and dimensions, they increase accordingly, which determines the installation possibilities. The latter is especially true in Free Air subwoofers (see "Execution"): some cars are initially equipped with "seats" for a certain size, and it is difficult to install models with other dimensions there.

Now on the market there are subwoofers with such popular sizes: 5" (13 cm), 6" (15.25 cm), 6.3" (16 cm), 6.5" (16.5 cm), 6.75" (17 cm), 8" (20 cm ), 8.25"(21cm) , 9" (23cm ), 10" (25cm ), 11" (27cm), 12"(30cm) , 13" (33cm), 15"(38cm) , 16 " (40 cm), 18" (46 cm).

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.

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.

Woofer Diameter

Subwoofer main speaker size. The diameter of the woofer determines the size of the device (see above).
