Talking to big crowds takes a massive voice. Using a Bull Horn is usually the best and most efficient way to go. Our trigger talk bullhorns are made out of high impact plastic with a built in microphone and are weather proof. With differing ranges up to 1,000 yards, you can make sure you are heard, loud and clear, no matter how far away you are to your audience.
DID YOU KNOW? The initial inventor of the "speaking trumpet" is a subject of historical controversy, as both Samuel Morland and Athanasius Kircher lay claim to the device. Morland, in a work published in 1655, wrote about his experimentation with different horns and his most successful variant. This loudest horn was made of over 20 feet of copper and could supposedly project vocalizations as far as a mile and a half. Twenty years earlier, Kircher described a device that could be used for both broadcasting on one end and “overhearing” on the other. His coiled horn would be wedged into the side of a building, connecting a speaker or listener inside with the surrounding environment. The term "megaphone" or "bullhorn" were not used until the late 19th century.
