What are the components inside the loudspeaker?

The task of the loudspeaker is to convert the electronic signals of the audio system into sound energy that can be perceived by human beings. In the vast majority of cases, the closer the output is to the input, the better the result (that is, high fidelity).

It is also important to understand that no matter how good a speaker you are using, a substandard input source will always detract from sound quality.

Professional speakers usually contain multiple units (components) in a single speaker. The most common design is called a "two divider", with two components providing output together.

A two-tone design usually includes a tapered bass unit with a 15 - or 12-inch diameter, a small (1 - to 1.5 - inch) treble unit, and a horn that provides a specified coverage Angle.

A general overview of a typical two-frequency speaker assembly: horn units, dividers, and tapered woofers are found in wooden speakers or in more and more polycompound speakers.

For bass units that reproduce low frequencies, the box provides a surface that radiates the output directly into the surrounding environment.

In contrast, if the high frequencies of unit processing are sent directly into the coverage area, it is almost impossible to hear them. The unit must therefore be matched to the horn in order to extend the sound from the unit into the surrounding environment at a specified frequency and diffusion Angle.

As a result, the horn/unit installation greatly improves efficiency, providing the loudness of the entire room with only a few watts of input.

Inside the loudspeaker, the input signal is distributed through a passive frequency division network to two units, commonly called dividers, which directly distribute the low frequencies to the bass units and the high frequencies to the treble units.
