This series of speakers are weatherproof outdoor column speakers with a 70V/100V transformer built in. The 70V/100V transmission is realized in a high-voltage, low-current mode, which makes longer distance transmission and parallel connection of multiple loudspeakers possible. It can be applied to outdoor occasions vary in area sizes and background noises, such as station, park, school, square, military camp, industrial park, beach, etc.
