The AmpliVox S601 Piezo Dynamic Megaphone is an incredibly lightweight and energy efficient megaphone with a surprisingly loud voice.
The Piezo Dynamic Technology means solid state circuitry which produces superior efficiency in a featherlight package. This is accomplished through full-sized diaphragms and ceramic wafers. By eliminating traditional megaphone magnets, the weight is eliminated and the full-frequency response and loudness of voice coils remains.
