Megaphones

Piezo Dynamic Technology is a revolutionary technique that allows megaphones to operate more efficiently and with less weight than ever before. The technology utilizes full-sized diaphragms and ceramic wafers to create the full-frequency response and loudness of voice coil speakers, without the use of heavy, cumbersome magnets as in conventional megaphones, significantly reducing weight and current draw. Our megaphones are less than half the weight of competitors and give 3 to 4 times the battery life!
