Megaphones

SupplyApp's megaphones will ensure that people hear you. Select horns with diameters ranging from 7.5" to 14" and power ratings ranging from 10W to 45W. Up to 1-3/8 miles, the higher-powered battery-operated megaphones attract attention. The microphones on some speakers can be detached. There's also a storage case for megaphones here. SupplyApp double-checks that you're prepared.
