Glossary

Tweeter size

Size of the high-frequency speaker(s) included in the speaker design.

Size affects the amount of space required to install the speaker. However, high frequencies do not require large diffusers, so this dimensions is usually small and does not significantly affect the overall dimensions of the speaker system. The only exception is individual high-frequency tweeters (see "Type"), where the overall dimensions of the housing are directly related to the dimensions of the diffuser.

Midrange speaker diameter

The diameter of the midrange speaker(s) provided in the speaker. Midrange in this case may also mean a combined woofer/midrange speaker or an emitter of broadband acoustics (see "Type").

The size of the midrange speaker is often a key parameter that determines the overall dimensions of the acoustics and, accordingly, the requirements for its installation location. Exceptions can only be found among models with separate woofers (see below). But from the point of view of acoustics, a larger size allows you to achieve higher power and richer sound, including on bass.

Woofer size

Size of the low-frequency speaker(s) provided in the speaker system.

This size is specified only for models with separate bass speakers. In such acoustics, it is the LF emitter that is the largest (this is due to the physical characteristics of the bass range). Accordingly, the space occupied by the entire system is determined mainly by the diameter of the LF speaker. And since the power and richness of the bass also directly depends on the size of the emitter, then when choosing, you have to proceed from a compromise between the capabilities of the acoustics and the available space in the car.
