How would one build an amplified (electronic) megaphone?
Sup guys. Im trying to start buildign an electronic megaphone, but i dont know where to ger started. I've looked online enough on building and amp, but dont know if using a microphone requires a preamp on it. So far, i have a plastic cone for the physical part, and a 4 ohm 10W mid-tweet speaker to project the sound. All i need is to know if a pocket amp is sufficient to amp a passive mic loud enough over a crowd. I need need any superb audio quality, just something that you can actually hear what is being said. I would appreciate any plans and help. TY
