The Tesla fiberglass street loudspeaker from the 1980s stands as a symbol of public sound systems in socialist Czechoslovakia. This durable speaker, often mounted on streetlight poles, broadcasted municipal announcements, signature jingles, and urgent messages.
Its sturdy fiberglass construction resisted rain, frost, and heat, while the internal electroacoustic system ensured powerful and clear sound. It was a familiar fixture in streets, squares, and factories, delivering both ideological slogans and popular folk and contemporary songs.
