Check out this video from YouTube of a bullhorn megaphone demonstration!
Pretty powerful stuff here. He is reviewing the Fanon MV20s Bullhorn Megaphone that I have also reviewed here in the past.
About
We set up this site, Bullhorn Megaphone, to provide accurate and realistic information about megaphones and other loudspeaker systems. There is a surprising lack of information on the net about these devices, so we think of this site as their little home!
