At work the other day and cleaning up some stuff and found this giant compression horn. Looks like a replacement for the old base announcement system that we used to have here. If it is then this thing is incredibly loud. the motor is like 7-8 inches across alone. Anyone know who makes these or what kind of power these run? There are no markings on it other than what is on the bottom. Thinking about just selling it on here as I have no need for something that can get as loud as this thing. What is it worth? That is standard 8" by 11" paper next to it so you have a reference for the size of this thing.
