Medium (loudspeaker)

A medium is a Haut-parleur with a rather broad membrane making it possible to reproduce sounds located in the average zone of the audio frequencies, i.e. between the serious S and the acute S.

According to the quality and the complexity of manufacture, a loudspeaker medium speaks in a beach about frequency included/understood:

between 500 Hz and 5000 Hz for standard médiums;
between 150 Hz and 3000 Hz for top-of-the-range médiums;
between 100 Hz and 10 Khz for médiums broad band.

In the construction of an enclosure high-fidelity, the quality of the loudspeaker medium is paramount because the sounds which it is supposed to reproduce find in the beach of the Fréquence S to which the human Oreille is most sensitive. The human voice as well as the majority of the musical instruments (besides some exceptions like the Piano, the Organ or the Piccolo) produces usually frequencies ranging between 100 Hz and 4000 Hz. This is why in the stereo mini-chains and the sound equipment minimalists, the sound enclosure simplest will be made up only of one loudspeaker and it will be a medium.

Generally, good a pregnant high-fidelity consists of three loudspeakers: a boomer for the low registers, a medium and a Tweeter for the acute ones.

Paradoxically, in wiring for sound, the loudspeaker medium is seldom used. One substitutes to him the trumpet medium using a room with compression and allowing thus more power by projecting the sound ahead, with the inevitable detriment of sound quality.
