Array system of exponential loudspeakers 50 W. Array of exponential loudspeakers for message diffusion more than 600 m away (against the usual 300 m of a conventional exponential). The most common areas of application are airports, ski slopes, factories, theme parks and, in general, the sounding of large populated areas in case of catastrophes, such as populations near nuclear power stations or areas affected by earthquakes.
