Passive emitter computer speakers

Passive emitter

— a passive radiator can be described as a separate speaker without a coil — the membrane of such a "speaker" vibrates only due to sound from other speakers. Due to this, you can noticeably improve the sound quality, especially at low frequencies. A phase inverter performs a similar function (see the relevant paragraph), however, a passive radiator is not so prone to extraneous noise. In addition, the installation of such a radiator does not increase the depth of the column, but another dimension — usually height; in some cases, this moment also turns out to be an advantage.
