Frequency range
The total audio frequency range reproduced by all speaker speakers.
Obviously, this range should not be too narrow, so that the acoustics do not cut off the lower and/or upper frequency limits of the reproduced sound. At the same time, the human ear perceives sound within 16 Hz - 22 kHz, and it simply does not make sense to provide speakers with a wider frequency range. We also recall that in
mid-frequency acoustics and tweeters, reproducible frequencies are limited due to specialization (for more details, see "Type"). And the overall sound quality will depend not only on this indicator, but also on a number of other features.
Tweeter diameter
The diameter of the tweeter (speakers) provided in the design of the speaker.
The diameter affects the amount of space needed to install the speaker. However, large cones are not needed for high frequencies, so this dimensions is usually small and does not really affect the overall dimensions of the speaker. The only exception is separate tweeter tweeters (see "Type"), where the overall dimensions of the cabinet are directly related to the dimensions of the cone.
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.
