tweeter

In the case of loudspeakers, a distinction is made between tweeters ( HT), midrange drivers( MT) and woofers(TT) in terms of frequency characteristics. In loudspeaker cabinets, tweeters are combined with woofers to form a two-way system and with midrange and woofers to form three-way systems.

Tweeters, tweeter, are designed for higher frequencies between 2 kHz and 4 kHz up to the highest audio frequencies at 20 kHz. To prevent them from being damaged or causing distortion due to high signal levels from low-frequency signals, crossovers with high-passfilters are placed in front of the tweeters. The air gap of tweeters is often filled with ferrofluid, an oily magnetic fluid.

In terms of loudspeaker technology, neodymium tweeters, dome loudspeakers, pressure chamber loudspeakers and funnel loudspeakers are used as tweeters, as are dynamic moving coil loudspeakers, ribbon loudspeakers and ion loudspeakers, or the less expensive piezo loudspeakers.

In sound reinforcement systems, the funnel loudspeaker is preferred over other tweeter loudspeakers because of its good efficiency, low distortion and defined dispersion characteristics.
